  2. Description of the Related Art Conventionally, an electric door opening / closing device that opens and closes openings (such as entrances and exits) formed in a vehicle body by electrically moving a door panel by a driving force of a motor or the like may be mounted on the vehicle. The electric door opening and closing device includes a foreign object for detecting a foreign object existing between the peripheral part of the opening and the door panel in order to detect the foreign object sandwiched between the peripheral part of the opening and the door panel.

  By the way, in a state where the opening of the vehicle body is closed by the door panel, there is a minute gap between the periphery of the opening of the vehicle body facing the holding member or the periphery of the door panel and the holding member. When the air temperature drops with water droplets entering the minute gap, the water droplets may freeze between the peripheral edge of the opening of the vehicle body facing the holding member or the peripheral edge of the door panel and the holding member. Then, the holding member and the peripheral portion of the opening of the vehicle body or the peripheral portion of the door panel facing the holding member may be connected by the frozen water droplets. When the door panel is opened in this state, a force in the direction of peeling the holding member from the bracket acts on the foreign matter detection sensor, and the foreign matter detection sensor may be peeled off from both longitudinal ends of the holding member.

  Therefore, in order to prevent the foreign object detection sensor from being peeled off from the bracket, it is conceivable that the both ends of the holding member in the longitudinal direction of the foreign object detection sensor are locked to the bracket. However, since the holding member is an elastic material, when the holding member is fixed to the bracket with an adhesive member, the holding member expands and contracts in the longitudinal direction. In addition, since the holding member has a long shape, an attachment error tends to occur in the longitudinal direction of the holding member when the holding member is fixed to the bracket. Therefore, there has been a problem that it is difficult to determine the position of the end of the holding member in the longitudinal direction with respect to the bracket. As a result, it has been difficult to lock the both end portions of the holding member in the foreign matter detection sensor in the longitudinal direction to the bracket.

  The present invention has been made in order to solve the above-mentioned problems, and the object thereof is to fix a foreign matter detection sensor capable of easily preventing peeling of both end portions in the longitudinal direction of a holding member from brackets, and An object of the present invention is to provide a fixing structure for a foreign matter detection sensor.

  A foreign object detection sensor fixing method that solves the above-described problem is a foreign object detection sensor that fixes an elongated foreign object detection sensor that detects an external object to an elongated bracket by being elastically deformed by receiving external force from the foreign object. A fixing method, wherein the foreign matter detection sensor has a sticking surface provided along a longitudinal direction, and holds a plurality of electrode wires that are in contact with each other when an external force from the foreign matter is transmitted to the inside.

A bracket side reference that is aligned in a direction, and an engagement portion that is provided at both ends in the longitudinal direction of the bracket and that engages with the mounting engagement portion, and the sensor side reference and the A reference alignment step for aligning the racket side reference with the longitudinal direction of the bracket, an engagement step for engaging the attachment engagement portion with the engagement portion, and after the reference alignment step, A fixing step of sequentially fixing the holding member to the bracket from the bracket side reference toward the engagement portion by an adhesive member interposed between the bracket and the engagement step. At least one of the attachment engaging portions is movable relative to the engaged engaging portion in the longitudinal direction of the bracket.

  According to this method, in the reference alignment step, by aligning the sensor side reference and the bracket side reference, a part in the longitudinal direction of the bracket and a part in the longitudinal direction of the foreign object detection sensor are aligned with each other in the longitudinal direction. Can be aligned. Further, by performing the fixing step, the holding member can be fixed to the bracket by the adhesive member in order from the sensor side reference to the engaging portion. Then, at least one of the attachment engaging portions is movable relative to the engaged engaging portion in the longitudinal direction of the bracket, and thus occurs when the holding member is fixed to the bracket with the adhesive member. A mounting error in the longitudinal direction of the holding member can be absorbed. Therefore, the both ends of the holding member in the foreign matter detection sensor in the longitudinal direction can be easily locked to the bracket. Furthermore, in order to engage the mounting engagement portions provided at both ends in the longitudinal direction of the holding member with the engagement portions provided at both ends in the longitudinal direction of the bracket, the holding member in the foreign matter detection sensor fixed to the bracket It is possible to easily prevent peeling of both end portions in the longitudinal direction from the bracket.

In the fixing method of the foreign matter detection sensor, it is preferable that the fixing step is performed after the engaging step.
According to this fixing method, the holding member is not fixed to the bracket by the adhesive member at the time of the engaging step, as compared with the case where the fixing step is performed before the engaging step. The degree of freedom of handling is high. Thereby, the assembly | attachment property with respect to the engaging part of an attachment engaging part can be improved.

In the fixing method of the foreign matter detection sensor, it is preferable that the attachment engaging portion and the engaging portion are elastically engaged in the engaging step performed after the fixing step.
According to this fixing method, since the fixing step of fixing the holding member to the bracket by the adhesive member is performed in a state where the attachment engaging portion and the engaging portion before the engaging step are not engaged, the holding member is bonded. The degree of freedom when fixing with a member can be maintained. Therefore, when the bracket is not a simple shape such as a straight line but a complicated shape having a plurality of curved portions, the assembling property of the holding member can be effectively improved. In addition, since the holding member is fixed before the engagement step, the mounting engagement portion is restricted to some extent in the engagement step, but the attachment engagement portion and the engagement portion are elastically engaged. Therefore, it is possible to easily assemble the attachment engagement portion and the engagement portion.

  Preferably, the foreign matter detection sensor fixing method includes an attachment engagement portion fixing step of fixing the attachment engagement portion and the engagement portion immovably after the engagement step and the fixation step.

  According to this configuration, when fixing the foreign object detection sensor to the bracket, by aligning the sensor side reference and the bracket side reference, a part in the longitudinal direction of the bracket and a part in the longitudinal direction of the foreign object detection sensor are obtained. They can be aligned in the longitudinal direction of each other. Moreover, since the holding member is fixed to the bracket by the adhesive member in order from the bracket side reference toward the mounting engagement portion, the holding member can be firmly fixed to the bracket. Then, at least one of the attachment engaging portions is movable relative to the engaged engaging portion in the longitudinal direction of the bracket, and thus occurs when the holding member is fixed to the bracket with the adhesive member. A mounting error in the longitudinal direction of the holding member can be absorbed. Therefore, the both ends of the holding member in the foreign matter detection sensor in the longitudinal direction can be easily locked to the bracket. Furthermore, the brackets at both ends in the longitudinal direction of the holding member are engaged by engaging the mounting engaging portions provided at both ends in the longitudinal direction of the holding member with the engaging portions provided at both ends in the longitudinal direction of the bracket. Peeling from can be easily prevented.

  According to this configuration, when fixing the foreign object detection sensor to the bracket, by aligning the sensor side reference and the bracket side reference, a part in the longitudinal direction of the bracket and a part in the longitudinal direction of the foreign object detection sensor are obtained. They can be aligned in the longitudinal direction of each other. Moreover, since the holding member is fixed to the bracket by the adhesive member in order from the bracket side reference toward the mounting engagement portion, the holding member can be firmly fixed to the bracket. Then, at least one of the engaging portions at both ends of the bracket has a shape that allows movement of the engaged mounting engaging portion in the longitudinal direction of the bracket, and thus the holding member is fixed to the bracket with an adhesive member. A mounting error in the longitudinal direction of the holding member that sometimes occurs can be absorbed. Therefore, the both ends of the holding member in the foreign matter detection sensor in the longitudinal direction can be easily locked to the bracket. Furthermore, the brackets at both ends in the longitudinal direction of the holding member are engaged by engaging the mounting engaging portions provided at both ends in the longitudinal direction of the holding member with the engaging portions provided at both ends in the longitudinal direction of the bracket. Peeling from can be easily prevented.

It is a joint. Therefore, it is not necessary to separately provide the sensor side reference for the foreign matter detection sensor or separately provide the bracket side reference for the bracket. Therefore, it can suppress that the structure of a foreign material detection sensor and a bracket is complicated. Further, the sensor side reference is aligned with the bracket side reference by engaging one attachment engagement portion that is the sensor side reference with one engagement portion that is the bracket side reference. Accordingly, the step of aligning the sensor side reference and the bracket side reference and the step of engaging one mounting engagement portion with one engagement portion are performed at the same time. Can be fixed to the bracket.

  In the fixing structure of the foreign matter detection sensor, the foreign matter detection sensor has a lead wire connected to the electrode wire on either one end side of both end portions in the longitudinal direction of the holding member, and the sensor side It is preferable that one of the attachment engaging portions serving as a reference is provided at an end portion on the side where the lead wire is connected to the electrode wire among both end portions in the longitudinal direction of the holding member.

  According to this configuration, since the mounting engagement portion provided at the longitudinal end of the holding member on the side where the lead wire is connected to the electrode wire is the sensor side reference, the mounting engagement portion is The position in the longitudinal direction with respect to the bracket is determined by being engaged with the reference engaging portion. Therefore, the end of the lead wire on the side connected to the electrode wire is easily positioned. Therefore, since it is difficult for an error to occur in the position of the lead wire, it is easy to arrange the lead wire connected to the electrode wire and to connect the end portion of the lead wire opposite to the electrode wire. In addition, since it is difficult for an error to occur in the position of the lead wire, the design for the lead wire becomes easy.

Generally, when fixing a holding member to a bracket with an adhesive member, the holding member is likely to be displaced in the longitudinal direction with respect to the bracket as the bracket is curved. Therefore, by providing a bracket-side reference in the curved portion and fixing the holding member in order from the bracket-side reference toward the engaging portions on both sides, it is possible to suppress a mounting error in the longitudinal direction of the holding member with respect to the bracket. it can. Therefore, the amount of movement of the bracket in the longitudinal direction relative to the engaging portion of the attachment engaging portion due to the attachment error in the longitudinal direction of the holding member can be reduced. As a result, the length of the bracket in the longitudinal direction at the engaging portion can be shortened.

  In the foreign matter detection sensor fixing structure, it is preferable that the sensor-side reference and the bracket-side reference are engaged with each other and fixed so as not to be relatively movable in the longitudinal direction of the bracket.

That is, it can suppress that the attachment error of the holding member with respect to the bracket in the longitudinal direction is biased toward one of the two attachment engagement portions. Therefore, the amount of movement of the bracket in the longitudinal direction with respect to the engagement portion of each attachment engagement portion due to the attachment error in the longitudinal direction of the holding member can be reduced. As a result, the length of the bracket in the longitudinal direction at each engaging portion can be shortened.

That is, the engaging portion of the bracket is formed in a shape that more effectively allows the mounting engaging portion to move in the longitudinal direction of the bracket, and thereby the holding member is fixed to the bracket by the adhesive member. The attachment error in the longitudinal direction of the holding member generated in the above can be suitably absorbed.

In the fixing structure of the foreign matter detection sensor, it is preferable that the sticking surface is provided at a position different from the attachment engagement portion in the longitudinal direction of the holding member.
According to this configuration, the attachment engagement portion and the engagement portion can be easily engaged, which can contribute to an improvement in assembling property.

Further, in each bracket 81, a portion adjacent to the positioning convex portion 84 and the width direction of the bracket 81 is an adhesive surface 85 to which the hollow insulator 22 is fixed.

  Further, as shown in FIG. 7A, a first engagement portion 86 is formed at one end portion in the longitudinal direction of each bracket 81 (an end portion on the upper side of the vehicle 1), and the length of each bracket 81 is long. A second engagement portion 87 is formed at the other end portion in the direction (the end portion on the lower side of the vehicle 1). In FIG. 7A, in accordance with FIG. 1, one end portion in the longitudinal direction of the bracket 81 (the end portion on the upper end side of the door panel 5) is shown on the lower side, and the other end in the longitudinal direction of the bracket 81. The part (the end part which becomes the lower end side of the door panel 5) is illustrated on the upper side.

  The first engaging portion 86 has a slit shape that is cut from one end of the bracket 81 in the longitudinal direction toward the center portion of the bracket 81 in the longitudinal direction. The first engaging portion 86 is formed at a substantially central portion in the width direction of the bracket 81 at one end portion in the longitudinal direction of the bracket 81.

That is, the first engaging portion 86 has a slit shape that is cut from one end portion in the longitudinal direction of the bracket 81 toward the central portion in the longitudinal direction.

  As shown in FIGS. 10A and 10B, the longitudinal length of the bracket 81 in the first engaging portion 86 is the same as the longitudinal direction of the sensor portion 21 in the first mounting engaging portion. It is formed longer than the length. Thus, a gap S is formed between the first engagement portion 86 on the bracket 81 side and the first attachment engagement portion 42 on the sensor side. That is, the first attachment engagement portion 42 is engaged with the first engagement portion 86 in a loosely fitted state with a margin in the longitudinal direction. Further, the width of the first engagement portion 86 is the width of the portion of the first attachment engagement portion 42 where the first engagement recess 42a is provided (the width between the bottom surfaces 42b of the pair of first engagement recesses 42a). Are formed approximately equal.

  As shown in FIG. 7A, the second engaging portion 87 has a slit shape that is cut from the other end in the longitudinal direction of the bracket 81 toward the central portion in the longitudinal direction of the bracket 81. The second engaging portion 87 is formed at a substantially central portion in the width direction of the bracket 81 at the other end portion in the longitudinal direction of the bracket 81. Further, the second engaging portion 87 penetrates the bracket 81 in the thickness direction and opens to the opposite side to the central portion in the longitudinal direction of the bracket 81. As shown in FIGS. 9A and 9B, the length of the bracket 81 in the longitudinal direction of the second engagement portion 87 is the same as the length of the sensor portion 21 in the second attachment engagement portion 72 in the longitudinal direction. Are equally formed. Furthermore, the width of the second engagement portion 87 is the width of the portion of the second attachment engagement portion 72 where the second engagement recess 72a is provided (the width between the bottom surfaces 72b of the pair of second engagement recesses 72a). It is formed approximately equally.

  The foreign object detection sensor 13 is fixed to the bracket 81 in a state where the first attachment engagement portion 42 and the second attachment engagement portion 72 are engaged with the bracket 81. The second attachment engaging portion 72 is connected to the second engagement portion 87 between the pair of second engagement recesses 72a in the second attachment engagement portion 72 (that is, the bottom surfaces 72b of the pair of second engagement recesses 72a). The intermediate portion is engaged with the bracket 81 by being inserted. Furthermore, the portions of the bracket 81 on both sides of the second engagement portion 87 are inserted into the pair of second engagement recesses 72a. Accordingly, since the second mounting engagement portion 72 is locked to the bracket 81 in the direction orthogonal to the attaching surface 22a, the second end of the hollow insulator 22 provided with the second mounting engagement portion 72 is provided. The portion 22f is locked to the bracket 81 in a direction orthogonal to the attaching surface 22a. The second attachment engagement portion 72 is in contact with the bottom surface 87 a of the second engagement portion 87 and is positioned in the longitudinal direction with respect to the bracket 81. That is, the second mounting engagement portion 72 is a sensor side reference provided in the foreign object detection sensor 13 as much as a reference for positioning the hollow insulator 22 and the bracket 81 in the longitudinal direction. The second engagement portion 87 is a bracket side reference that is aligned with the sensor side reference in the longitudinal direction. Further, as shown in FIGS. 10A and 10B, the first attachment engagement portion 42 is connected to the first engagement portion 86 with a pair of first engagements in the first attachment engagement portion 42. The portion between the concave portions 42a (that is, the portion between the bottom surfaces 42b of the pair of first engaging concave portions 42a) is inserted to be engaged with the bracket 81. Furthermore, the portions of the bracket 81 on both sides of the first engagement portion 86 are inserted into the pair of first engagement recesses 42a, respectively. Accordingly, since the first attachment engaging portion 42 is locked to the bracket 81 in a direction orthogonal to the attaching surface 22a, the first end of the hollow insulator 22 provided with the first attachment engaging portion 42 is provided. The part 22e is locked to the bracket 81 in a direction orthogonal to the sticking surface 22a. Since the first engagement portion 86 is formed longer than the length of the sensor portion 21 in the longitudinal direction of the first attachment engagement portion 42, the first attachment engagement portion 42 is the first engagement portion 86. While being engaged, the first engaging portion 86 can be moved in the longitudinal direction of the bracket 81 while being guided by the first engaging portion 86. Then, the foreign matter detection sensor 13 has a double-sided tape 91 (adhesion) interposed between the adhering surface 22a and the adhering surface 85 while the one abutting portion 22b of the hollow insulator 22 is in contact with the positioning convex portion 84. The member 81 is attached to the bracket 81. As described above, the foreign matter detection sensor 13 is fixed to the bracket 81 with the double-sided tape 91.

  As shown in FIGS. 1, 9A, and 9B, the two lead wires 61, 62 extending from the second attachment engaging portion 72 of the second sealing member 54 have a first end. After extending in parallel with the sensor portion 21 toward the portion 22e (left side in FIG. 9), it is drawn into the door panel 5. As shown in FIG. 2, one of the two lead wires 61 and 62 drawn into the door panel 5 is electrically connected to the energization detection unit 14 inside the door panel 5. . Further, of the two lead wires 61 and 62, the other lead wire 62 is connected to the ground GND inside the door panel 5 (that is, grounded to the vehicle body 3).

  As shown in FIGS. 1 and 2, the energization detection unit 14 is disposed inside the door panel 5. The energization detection unit 14 supplies current to the electrode wire 23. In a normal state in which an external force such as a pressing force is not applied to the sensor unit 21, the current supplied from the energization detection unit 14 to the electrode wire 23 flows to the electrode wire 24 through the resistor 35. On the other hand, when an external force that crushes the sensor unit 21 is applied, the hollow insulator 22 in the portion where the external force is applied is elastically deformed, and the electrode wires 23 and 24 are bent along with the elastic deformation of the hollow insulator 22. Then, the electrode wire 23 and the electrode wire 24 come into contact with each other and are short-circuited. Then, the current supplied from the energization detection unit 14 to the electrode wire 23 flows to the electrode wire 24 without passing through the resistor 35. Therefore, for example, when a current is supplied to the electrode wire 23 at a constant voltage, the current value changes. Therefore, the energization detection unit 14 detects the change in the current value at this time, thereby detecting the sensor unit. The foreign matter that has come into contact with 21 is detected. And when the electricity supply detection part 14 detects the change of this electric current value, ie, detects the foreign material which contacted the foreign material detection sensor 13, it will output a foreign material detection signal to the door ECU101 mentioned later. In addition, when the external force with respect to the sensor part 21 is removed, the hollow insulator 22 will be restored, and the electrode wires 23 and 24 will also be restored and become non-conductive.

  The electric back door device 2 includes a door ECU 101 that controls the opening / closing operation of the door panel 5 by the actuator 6 inside the door panel 5. The door ECU 101 includes a ROM (Read only Memory), a RAM (Random access Memory), and the like and has a function as a microcomputer, and is supplied with power from a battery (not shown) of the vehicle 1. Further, the door ECU 101 supplies a current to the energization detection unit 14 that is electrically connected to the door ECU 101. The door ECU 101 controls the actuator 6 based on various signals input from the operation switch 9, the position detection device 8, the energization detection unit 14, and the like.

Next, the operation of the electric back door device 2 configured as described above will be comprehensively described.
When an open signal is input from the operation switch 9, the door ECU 101 drives the actuator 6 to open the door panel 5. The door ECU 101 recognizes the rotational position of the door panel 5 based on the position detection signal input from the position detection device 8. In the present embodiment, the door ECU 101 counts the number of pulses of the position detection signal, and recognizes the rotational position of the door panel 5 based on the count value. When the door panel 5 is disposed at the fully closed position, the door ECU 101 stops the actuator 6.

  On the other hand, when a close signal is input from the operation switch 9, the door ECU 101 drives the actuator 6 to close the door panel 5. When the door panel 5 is disposed at the fully closed position, the door ECU 101 stops the actuator 6. In addition, during the closing operation of the door panel 5, if a foreign object comes into contact with the sensor unit 21 of the foreign object detection sensor 13 and an external force is applied to the sensor unit 21, the hollow insulator 22 is elastically deformed in the foreign object detection sensor 13. As a result, the electrode wire 23 and the electrode wire 24 come into contact with each other and are short-circuited. As a result, since the current value of the current supplied to the electrode wire 23 changes, the energization detection unit 14 outputs a foreign object detection signal to the door ECU 101. When the foreign object detection signal is input, the door ECU 101 reverses the actuator 6 to open the door panel 5 by a predetermined amount and then stops the actuator 6.

Next, a fixing method of the foreign object detection sensor 13 for fixing the foreign object detection sensor 13 configured as described above to the bracket 81 will be described together with the operation of the fixing structure of the foreign object detection sensor 13.

As shown in FIGS. 9A and 9B, in this reference matching step, the sensor side reference provided in the foreign matter detection sensor 13, that is, the second mounting engagement portion 72 and the bracket 81 are provided. Positioning is performed by engaging the bracket side reference, that is, the second engaging portion 87. Specifically, the portion between the pair of second engagement recesses 72 a in the second attachment engagement portion 72 (that is, the portion between the bottom surfaces 72 b of the pair of second engagement recesses 72 a) is replaced with the bracket 81 in the second engagement portion 87. The second mounting engagement portion 72 is engaged with the other end portion of the bracket 81 in the longitudinal direction by being inserted into the second engagement portion 87 through the opening facing the opposite side of the central portion in the longitudinal direction. At this time, portions on both sides of the second engaging portion 87 of the bracket 81 are inserted into the pair of second engaging recesses 72a. Accordingly, since the second mounting engagement portion 72 is locked to the bracket 81 in the direction orthogonal to the attaching surface 22a, the second end of the hollow insulator 22 provided with the second mounting engagement portion 72 is provided. The portion 22f is locked to the bracket 81 in a direction orthogonal to the sticking surface 22a. Then, the second attachment engagement portion 72 is positioned in the longitudinal direction with respect to the bracket 81 by bringing the second attachment engagement portion 72 into contact with the bottom surface 87 a of the second engagement portion 87. A double-sided tape 91 is attached to the attachment surface 22 a of the hollow insulator 22. A release paper is attached to a surface of the double-sided tape 91 opposite to the sticking surface 22a, and the double-sided tape 91 is not stuck to the bracket 81 or the like in the reference matching step.

  Next, an engaging step of engaging the first attachment engaging portion 42 with the first engaging portion 86 is performed. In this engagement step, as shown in FIGS. 10A and 10B, a portion between the pair of first engagement recesses 42a in the first attachment engagement portion 42 (that is, the pair of first engagement recesses). The first attachment portion 86 is inserted into the first engagement portion 86 through the opening facing the opposite side of the central portion in the longitudinal direction of the bracket 81 in the first engagement portion 86. The engaging portion 42 is engaged with the other end portion of the bracket 81 in the longitudinal direction. At this time, the portions on both sides of the first engaging portion 86 of the bracket 81 are inserted into the pair of first engaging recesses 42a, respectively. Accordingly, since the first attachment engaging portion 42 is locked to the bracket 81 in a direction orthogonal to the attaching surface 22a, the first end of the hollow insulator 22 provided with the first attachment engaging portion 42 is provided. The portion 22e is locked to the bracket 81 in a direction orthogonal to the sticking surface 22a. Since the first engagement portion 86 is formed longer than the length of the sensor portion 21 in the longitudinal direction of the first attachment engagement portion 42, the first attachment engagement portion 42 is the first engagement portion 86. While being engaged, the first engaging portion 86 can be moved in the longitudinal direction of the bracket 81 while being guided by the first engaging portion 86. In the present embodiment, the reference matching step is a step of engaging the second attachment engagement portion 72 with the second engagement portion 87, and thus also serves as an engagement step.

  Next, a fixing step of fixing the hollow insulator 22 to the bracket 81 with the double-sided tape 91 is performed. In this fixing step, from the second engagement portion 87 which is the bracket side reference toward the first engagement portion 86 (that is, from the second attachment engagement portion 72 side which is the sensor side reference to the first attachment engagement portion 42). The hollow insulator 22 is sequentially attached to the adhesive surface 85 of the bracket 81 by the double-sided tape 91 interposed between the attachment surface 22a and the bracket 81 while peeling the release paper. At this time, as shown in FIG. 8, a double-sided tape is used while positioning the hollow insulator 22 in the width direction with respect to the bracket 81 by bringing one abutment portion 22b of the hollow insulator 22 into contact with the positioning convex portion 84. 91 is adhered to the adhesive surface 85. Then, the double-sided tape 91 attached to the hollow insulator 22 is attached to the adhesive surface 85 over the entire length from the second attachment engagement portion 72 side to the first attachment engagement portion 42 side along the longitudinal direction. This completes the fixing process. Thereby, the hollow insulator 22 is fixed to the bracket 81 by the double-sided tape 91.

  In this fixing step, the bracket with respect to the first engagement portion 86 remains in a state where the first attachment engagement portion 42 is engaged with the first engagement portion 86 according to the attachment error in the longitudinal direction of the hollow insulator 22. 81 moves in the longitudinal direction. That is, the attachment error in the longitudinal direction of the hollow insulator 22 is absorbed by the first attachment engagement portion 42 moving in the longitudinal direction of the bracket 81 with respect to the first engagement portion 86. Therefore, due to the mounting error in the longitudinal direction of the hollow insulator 22, the first mounting engaging portion 42 and the second mounting engaging portion 72 provided at both ends of the hollow insulating body 22 are changed into the first engaging portion 86 and the second engaging portion 72. It is suppressed that it becomes difficult to be engaged with the engaging portion 87 and the end portion in the longitudinal direction of the hollow insulator 22 is difficult to be fixed to the bracket 81.

As described above, the present embodiment has the following effects.
(1) When fixing the foreign matter detection sensor 13 to the bracket 81, by aligning the sensor side reference and the bracket side reference, a part in the longitudinal direction of the bracket 81 and a part in the longitudinal direction of the foreign matter detection sensor 13 Can be aligned in the longitudinal direction of each other. And the 1st attachment engaging part 42 and the 2nd attachment engaging part 72 which were provided in the both ends of the longitudinal direction of the hollow insulator 22 are made into the 1st engaging part provided in the both ends of the longitudinal direction of the bracket 81. 86 and the second engaging portion 87 are engaged. Thereafter, the hollow insulator 22 can be fixed to the bracket 81 with the double-sided tape 91 in order from the second engagement portion 87 which is the bracket side reference toward the first engagement portion 86. At this time, the first attachment engagement portion 42 that is movable in the longitudinal direction of the bracket 81 with respect to the engaged first engagement portion 86 is engaged with the second engagement portion 87 that is the bracket side reference. In accordance with the attachment error in the longitudinal direction of the hollow insulator 22 that occurs when the hollow insulator 22 is fixed to the bracket 81 with the double-sided tape 91 in order toward the first engaging portion 86, the first engagement is achieved. It moves in the longitudinal direction of the bracket 81 with respect to the joint portion 86. Therefore, the longitudinal mounting error that occurs when the hollow insulator 22 is fixed to the bracket 81 can be absorbed by the movement of the first mounting engaging portion 42 relative to the first engaging portion 86. Therefore, both ends of the hollow insulator 22 in the longitudinal direction of the foreign object detection sensor 13 can be easily locked to the bracket 81. Furthermore, the first attachment engaging portions 42 and the second attachment engaging portions 72 provided at both ends in the longitudinal direction of the hollow insulator 22 are replaced with first engagement portions 86 provided at both ends in the longitudinal direction of the bracket 81. Further, by engaging with the second engaging portion 87, it is possible to easily prevent the both ends in the longitudinal direction of the hollow insulator 22 from being peeled off from the bracket 81.

  Moreover, in this embodiment, an engagement process is performed before a fixing process. For this reason, since the hollow insulator 22 is not fixed to the bracket 81 by the double-sided tape 91 at the time of the engagement step, compared to the case where the fixing step is performed before the engagement step, the first attachment member in the engagement step The degree of freedom of handling of the joint unit 42 (first terminal processing unit 31) is high. Thereby, the assembly | attachment property with respect to the 1st engagement part 86 of the 1st attachment engagement part 42 can be improved.

  (2) The sensor side reference is one of the two attachment engaging portions 42 and 72, and the bracket side reference is the second attachment engaging portion 72 which is the sensor side reference. It is the 2nd engaging part 87 engaged. Therefore, it is not necessary to separately provide the sensor side reference to the foreign matter detection sensor 13 or to separately provide the bracket side reference to the bracket 81. Therefore, it can suppress that the structure of the foreign material detection sensor 13 and the bracket 81 is complicated. Further, by engaging the second attachment engagement portion 72 that is the sensor side reference with the second engagement portion 87 that is the bracket side reference, the sensor side reference is aligned with the bracket side reference. Accordingly, the step of aligning the sensor side reference and the bracket side reference and the step of engaging the second mounting engagement portion 72 with the second engagement portion 87 are performed at the same time. The detection sensor 13 can be fixed to the bracket 81.

  (3) Since the second mounting engagement portion 72 provided at the second end 22f of the hollow insulator 22 on the side where the lead wires 61 and 62 are connected to the electrode wires 23 and 24 is the sensor side reference, The second attachment engagement portion 72 is engaged with a second engagement portion 87 that is a bracket side reference, so that the position in the longitudinal direction with respect to the bracket 81 is determined. Therefore, the end portions of the lead wires 61 and 62 on the side connected to the electrode wires 23 and 24 are easily positioned. Accordingly, since errors in the positions of the lead wires 61 and 62 are less likely to occur, the arrangement of the lead wires 61 and 62 connected to the electrode wires 23 and 24 and the energization of the end portion of the lead wire 61 opposite to the electrode wire 23 are prevented. It becomes easy to connect to the detection unit 14 and to the ground GND at the end of the lead wire 62 opposite to the electrode line 24. Further, since it is difficult for errors to occur in the positions of the lead wires 61 and 62, the design for the lead wires 61 and 62 is facilitated.

  (4) The first engaging portion 86 and the second engaging portion 87 have a slit shape that opens to the opposite side of the central portion of the bracket 81 in the longitudinal direction. In other words, the first engaging portion 86 and the second engaging portion 87 have a slit shape cut from the longitudinal end portion of the bracket 81 toward the longitudinal central portion, and are thereby engaged. The first and second mounting engagement portions 42 and 72 are allowed to move in the longitudinal direction. Accordingly, by inserting the first attachment engagement portion 42 into the first engagement portion 86 from the opening portion opened to the opposite side of the central portion in the longitudinal direction of the bracket 81 in the first engagement portion 86, the first attachment portion 86 is provided. The engaging portion 42 can be easily engaged with the first engaging portion 86. Similarly, by inserting the second attachment engagement portion 72 into the second engagement portion 87 from the opening portion opened to the opposite side to the central portion in the longitudinal direction of the bracket 81 in the second engagement portion 87, The attachment engagement portion 72 can be easily engaged with the second engagement portion 87. In addition, on the second end 22f side of the hollow insulator 22 provided with the second attachment engaging portion 72, lead wires 61 and 62 are connected to the electrode wires 23 and 24, and the lead wires 61 and 62 are The second mounting engagement portion 72 is pulled out. Furthermore, since the lead wires 61 and 62 are drawn into the door panel 5, the lead wires 61 and 62 are routed toward the surface opposite to the adhesive surface 85 to which the hollow insulator 22 is fixed in the bracket 81. Accordingly, when the second engaging portion 87 is opened on the opposite side to the central portion in the longitudinal direction of the bracket 81, the opening opened on the opposite side to the central portion in the longitudinal direction of the bracket 81 in the second engaging portion 87. The lead wires 61 and 62 can be easily routed from the portion toward the surface of the bracket 81 opposite to the bonding surface 85.

  (5) In the engaged state, a gap S is provided between the first attachment engaging portion 42 and the first engaging portion 86 in the longitudinal direction. That is, the first engaging portion 86 of the bracket 81 is formed in a shape that allows the movement of the first mounting engaging portion 42 in the longitudinal direction more effectively. An attachment error in the longitudinal direction of the hollow insulator 22 that occurs when it is fixed to the bracket 81 can be suitably absorbed.

  (6) Since the sticking surface 22a is provided at a position different from the first attachment engagement portion 42 in the longitudinal direction of the hollow insulator 22, the first attachment engagement portion 42 and the first engagement portion 86 are provided. It can be easily engaged, and can contribute to the improvement of assembly.

In addition, you may change the said embodiment as follows.
In the above embodiment, the engaging step is performed after the reference matching step. However, the reference alignment process may be performed after the engagement process. Moreover, you may perform a reference | standard adjustment process and an engagement process simultaneously.

  -The shape of the 1st attachment engagement part 42 and the 2nd attachment engagement part 72 is not restricted to the shape of the said embodiment. The 1st attachment engaging part 42 should just be a shape engaged with the 1st engaging part 86 and latched in the direction orthogonal to the sticking surface 22a with respect to the bracket 81. FIG. Moreover, the 2nd attachment engagement part 72 should just be a shape engaged with the 2nd engagement part 87 and latched in the direction orthogonal to the sticking surface 22a with respect to the bracket 81.

In the example illustrated in FIG. 11, the first sealing member 111 that constitutes the first terminal processing unit 31 includes a first terminal covering portion 41 and a first attachment engagement portion 112 that can be elastically deformed. The first attachment engaging portion 112 is integrally formed on the side surface of the first terminal covering portion 41 facing the bracket 81 in the thickness direction of the bracket 81. The first attachment engagement portion 112 includes an engagement shaft 112a extending from the side surface of the first terminal covering portion 41 facing the bracket 81 in the thickness direction of the bracket 81, and the engagement shaft 112 extending from the distal end of the engagement shaft 112a. It is comprised from the latching | locking part 112b extended toward the base end side of 112a. The engagement shaft 112a has a hollow shape. In addition, the engagement shaft 112a has the thickness of the thickest portion substantially equal to the width of the first engagement portion 86 when viewed from the longitudinal direction of the hollow insulator 22 (that is, in the state shown in FIG. 11). Further, the length of the engagement shaft 112 a is longer than the thickness of the bracket 81. The engaging portions 112b are provided on both sides in the width direction of the sticking surface 22a of the engagement shaft 112a (both sides in the left-right direction in FIG. 11), and are directed from the distal end of the engagement shaft 112a to the proximal end side. Accordingly, the width of the first attachment engaging portion 112 (the width in the same direction as the width direction of the sticking surface 22a) is increased. In such a first attachment engagement portion 112, the engagement shaft 112a is inserted into the first engagement portion 86, and the engagement shaft 112a penetrates the first engagement portion 86 in the thickness direction of the bracket 81. Is engaged with the first engaging portion 86. And the front-end | tip part of the latching | locking part 112b is the width direction of the 1st engaging part 86 in the bracket 81 on the opposite side to the side in which the 1st terminal coating | coated part 41 is arrange | positioned among the both sides of the thickness direction of the bracket 81. Touch the parts on both sides. Furthermore, the both sides in the width direction of the first engaging portion 86 in the bracket 81 are sandwiched between the locking portion 112 b and the first terminal covering portion 41. Accordingly, the first attachment engaging portion 112 is locked to the bracket 81 in a direction orthogonal to the attaching surface 22a. Further, the first attachment engaging portion 112 is movable in the longitudinal direction of the bracket 81 with respect to the bracket 81 while being engaged with the first engaging portion 86. In addition, you may change into the shape similar to the 1st attachment engagement part 112 shown in FIG. 11 also about the 2nd attachment engagement part 72 of the said 1st Embodiment.

  In the above embodiment, each of the first engaging portion 86 and the second engaging portion 87 has a slit shape that opens to the opposite side to the central portion in the longitudinal direction of the bracket 81. However, the shapes of the first engaging portion 86 and the second engaging portion 87 are not limited to this. The first engaging portion 86 locks the engaged first mounting engaging portion 42 in a direction orthogonal to the attaching surface 22a, and the hollow insulating body 22 provided with the first mounting engaging portion 42 is provided. Any shape can be used as long as the first end 22e can be locked to the bracket 81 in a direction orthogonal to the attaching surface 22a. Similarly, the second engagement portion 87 locks the engaged second attachment engagement portion 72 in a direction orthogonal to the sticking surface 22a, and is a hollow insulation provided with the second attachment engagement portion 72. What is necessary is just the shape which can latch the 2nd end part 22f of the body 22 with respect to the bracket 81 in the direction orthogonal to the sticking surface 22a. However, at least one of the first engagement portion 86 and the second engagement portion 87 can move the engaged first attachment engagement portion 42 and second attachment engagement portion 72 in the longitudinal direction of the bracket 81. .

  For example, the first engaging portion and the second engaging portion may be as illustrated in FIGS. 12 and 13. In FIG. 12 and FIG. 13, the same reference numerals are given to the same components as those in the above embodiment. As shown in FIG. 12A, the first sealing member 121 constituting the first terminal processing unit 31 is composed of a first terminal covering portion 41 and an elastically deformable first attachment engaging portion 122. ing. The first attachment engaging portion 122 is integrally formed on the side surface of the first terminal covering portion 41 facing the bracket 81 in the thickness direction of the bracket 81. The first attachment engagement portion 122 is provided integrally with the engagement shaft 122a extending from the side surface of the first terminal covering portion 41 facing the bracket 81 in the thickness direction of the bracket 81, and the distal end portion of the engagement shaft 122a. It is comprised from the latching | locking part 122b made. The engagement shaft 122a has a cylindrical shape and is longer than the thickness of the bracket 81. The locking portion 122b has an umbrella shape. And the outer peripheral surface of the latching | locking part 122b has comprised the cone shape from which the diameter becomes large as it approaches the base end side of the engagement shaft 122a from the front-end | tip part of the engagement shaft 122a.

  As shown in FIGS. 12A and 12B, the first engagement portion 131 with which the first attachment engagement portion 122 is engaged is one end portion in the longitudinal direction of the bracket 81 (the upper end side of the door panel 5). Are the holes formed at the end). The first engagement portion 131 penetrates the bracket 81 in the thickness direction, and the shape of the first engagement portion 131 viewed from the thickness direction of the bracket 81 is circular. Further, the diameter of the first engaging portion 131 is formed substantially equal to the diameter of the engaging shaft 122a. The first attachment engagement portion 122 is inserted into the first engagement portion 131 from the adhesive surface 85 side until the locking portion 122b penetrates the first engagement portion 131. Then, the engagement shaft 122a engages with the first engagement portion 131 in the longitudinal direction of the bracket 81. Further, the locking portion 122 b contacts the peripheral edge portion of the first engaging portion 131 in the bracket 81 on the side opposite to the first terminal covering portion 41. Therefore, the first sealing member 121 is locked to the bracket 81 in the direction orthogonal to the sticking surface 22 a by the first attachment engaging portion 122. As a result, the first end 22e of the hollow insulator 22 provided with the first attachment engaging portion 122 is locked to the bracket 81 in a direction perpendicular to the attaching surface 22a. In this example, the first attachment engagement portion 122 is a sensor side reference, and the first engagement portion 131 is a bracket side reference.

  Moreover, as shown to Fig.13 (a), the 2nd sealing member 141 which comprises the 2nd terminal process part 51 is from the 2nd terminal coating | coated part 71 and the 2nd attachment engagement part 142 which can be elastically deformed. It is configured. The second attachment engaging portion 142 is integrally formed on the side surface of the second terminal covering portion 71 facing the bracket 81 in the thickness direction of the bracket 81. The second attachment engagement portion 142 has the same shape as the first attachment engagement portion 122, and includes an engagement shaft 122a and a locking portion 122b.

  As shown in FIGS. 13A and 13B, the second engagement portion 132 with which the second attachment engagement portion 142 is engaged is the other end portion in the longitudinal direction of the bracket 81 (the lower end of the door panel 5). It is a long hole formed in the end portion on the side. The second engaging portion 132 has a groove shape that penetrates the bracket 81 in the thickness direction and extends in the longitudinal direction of the bracket 81. The width of the second engagement portion 132 (width in the short direction) is formed to be substantially equal to the diameter of the engagement shaft 122a, and the length of the second engagement portion 132 in the longitudinal direction is the engagement shaft. It is formed longer than the diameter of 122a. Thus, a gap S is formed between the second engagement portion 132 on the bracket 81 side and the second attachment engagement portion 142 (engagement shaft 122a) on the sensor side. The second attachment engagement portion 142 is inserted into the second engagement portion 132 from the adhesive surface 85 side until the locking portion 122b penetrates the second engagement portion 132. Then, the engagement shaft 122 a engages with the second engagement portion 132 in the longitudinal direction of the bracket 81. Further, the locking portion 122 b contacts the portions on both sides in the width direction of the second engaging portion 132 in the bracket 81 on the side opposite to the second terminal covering portion 71. Therefore, the second sealing member 141 is locked to the bracket 81 in the direction orthogonal to the sticking surface 22 a by the second attachment engaging portion 142. As a result, the second end 22f of the hollow insulator 22 provided with the second attachment engagement portion 142 is locked to the bracket 81 in a direction orthogonal to the attaching surface 22a. Further, the second attachment engaging portion 142 is movable in the longitudinal direction of the bracket 81 with respect to the second engaging portion 132 while being engaged with the second engaging portion 132.

  In the above embodiment, the sensor-side reference is the two attachment engagement portions (that is, the first attachment engagement portion 42 and the second attachment engagement portion 72) provided at both ends in the longitudinal direction of the hollow insulator 22. Of these, one second mounting engagement portion 72 is provided. And the bracket side reference | standard becomes the 2nd engagement part 87 with which the 2nd attachment engagement part 72 which is a sensor side reference | standard engages. However, the sensor side reference and the bracket side reference are not limited thereto. The sensor side reference only needs to be a position reference in the longitudinal direction with respect to the bracket 81 provided in the foreign object detection sensor 13. The bracket side reference only needs to be provided on the bracket 81 and aligned with the sensor side reference in the longitudinal direction.

  For example, in the example shown in FIG. 14, the bracket side reference is provided in the first bending portion 82 of the bracket 81. The bracket side reference is a locking hole 151 provided in the first bending portion 82. The locking hole 151 is provided in the central portion in the circumferential direction of the first curved portion 82 that is curved in an arc shape. The locking hole 151 is a hole penetrating the bracket 81 in the thickness direction, and the shape of the bracket 81 viewed from the thickness direction is circular.

  As shown in FIGS. 14 and 16B, in the bracket 81, the second engaging portion formed at the other end portion in the longitudinal direction of the bracket 81 (the end portion which becomes the lower end side of the door panel 5). 152 has the same shape as the first engaging portion 86 and is formed longer in the longitudinal direction of the bracket 81 than the second mounting engaging portion 72.

  As shown in FIG. 15, the sensor-side reference that is aligned with the locking hole 151 that is the bracket-side reference is a portion that is disposed on the first bending portion 82 in the hollow insulator 22 that constitutes the foreign object detection sensor 13. Is formed. The sensor-side reference is a reference locking portion 153 that is integrally formed on the sticking surface 22 a of the portion disposed on the first bending portion 82 in the hollow insulator 22. The reference locking portion 153 can be elastically deformed. The reference locking portion 153 includes an engagement shaft 153a extending perpendicularly from the bonding surface 22a to the bonding surface 22a, and a locking portion 153b provided at the tip of the engagement shaft 153a. ing. The engagement shaft 153 a has a columnar shape, and the diameter thereof is substantially equal to the diameter of the locking hole 151. Further, the length of the engagement shaft 153 a is formed to be slightly longer than the thickness of the bracket 81. The locking portion 153b has a conical shape whose outer diameter increases from the distal end side of the engagement shaft 153a toward the proximal end side of the engagement shaft 153a. The maximum diameter of the locking portion 153 b is larger than the diameter of the locking hole 151.

  As shown in FIGS. 14 and 15, when fixing such a foreign matter detection sensor 13 to the bracket 81, first, a reference alignment process is performed, and a reference locking portion 153 that is a sensor side reference is set on the bracket side reference. The sensor side reference and the bracket side reference are aligned in the longitudinal direction of the bracket 81 by being inserted into a certain locking hole 151 and engaged. The reference locking part 153 is inserted into the locking hole 151 from the adhesive surface 85 side until the locking part 153b penetrates the locking hole 151. Then, the engagement shaft 153 a engages with the locking hole 151 in the longitudinal direction of the bracket 81. That is, the reference locking portion 153 that is the sensor side reference and the locking hole 151 that is the bracket side reference are engaged with each other in the longitudinal direction of the bracket 81 so as not to move relative to each other and are fixed to each other. Further, the locking portion 153 b contacts the peripheral edge portion of the locking hole 151 in the bracket 81 on the side opposite to the hollow insulator 22. Then, the hollow insulator 22 is locked to the bracket 81 in a direction orthogonal to the sticking surface 22a by the reference locking portion 153. Next, an engagement step is performed to engage the first attachment engagement portion 42 with the first engagement portion 86 and engage the second attachment engagement portion 72 with the second engagement portion 152. Thereby, the first end 22e of the hollow insulator 22 provided with the first attachment engaging portion 42 is locked to the bracket 81 in a direction orthogonal to the attaching surface 22a. Furthermore, the second end 22 f of the hollow insulator 22 provided with the second attachment engaging portion 72 is locked to the bracket 81 in a direction orthogonal to the sticking surface 22 a. Further, the first attachment engagement portion 42 can move in the longitudinal direction of the bracket 81 with respect to the first engagement portion 86 while being engaged with the first engagement portion 86, and the second attachment engagement. The portion 72 is movable in the longitudinal direction of the bracket 81 with respect to the second engaging portion 152 while being engaged with the second engaging portion 152. Next, a fixing step is performed, and the gap between the attachment surface 22a and the bracket 81 is directed from the bracket side reference toward the first engagement portion 86 and from the bracket side reference toward the second engagement portion 152. The hollow insulator 22 is sequentially fixed to the bracket 81 by the interposed double-sided tape 91. At this time, similarly to the above-described embodiment, the first engagement portion 42 remains engaged with the first engagement portion 86 according to the attachment error in the longitudinal direction of the hollow insulator 22. It moves in the longitudinal direction of the bracket 81 with respect to 86. In addition, as shown in FIGS. 16A and 16B, the second attachment engagement portion 72 is engaged with the second engagement portion 152 in accordance with the attachment error in the longitudinal direction of the hollow insulator 22. The bracket 81 is moved in the longitudinal direction with respect to the second engaging portion 152 as it is.

  Even if it does in this way, the effect similar to (1) and (4) of the said embodiment can be acquired. In this example, the bracket side reference is provided in the first bending portion 82. In general, when the hollow insulator 22 is fixed to the bracket 81 with the double-sided tape 91, the portion where the bracket 81 is curved tends to be displaced in the longitudinal direction with respect to the bracket 81. Therefore, by providing a bracket side reference to the first bending portion 82 and fixing the hollow insulator 22 sequentially from the bracket side reference toward the first engagement portion 86 and the second engagement portion 152 on both sides, A mounting error in the longitudinal direction of the hollow insulator 22 with respect to the bracket 81 can be suppressed small. Therefore, the amount of movement of the bracket 81 in the longitudinal direction relative to the first engagement portion 86 of the first attachment engagement portion 42 due to the attachment error in the longitudinal direction of the hollow insulator 22, and the first due to the attachment error in the longitudinal direction of the hollow insulator 22. 2 The amount of movement of the bracket 81 in the longitudinal direction relative to the second engagement portion 152 of the attachment engagement portion 72 can be reduced. As a result, the length in the longitudinal direction of the bracket 81 in the first engaging portion 86 and the second engaging portion 152 can be shortened. Further, in this example, the sensor side reference is easily aligned with the bracket side reference by engaging and fixing the reference locking portion 153 that is the sensor side reference and the locking hole 151 that is the bracket side reference. be able to.

  In the examples shown in FIGS. 14 to 16, the engaging step may be performed before the reference matching step. Moreover, you may perform a reference | standard adjustment process and an engagement process simultaneously. Further, a locking hole 151 as a bracket side reference is provided in the second bending portion 83 of the bracket 81, and a reference locking portion 153 as a sensor side reference is disposed on the second bending portion 83 in the hollow insulator 22. You may form in.

  In addition, the sensor-side reference may be provided in the middle portion of the hollow insulator 22 in the longitudinal direction, and the bracket-side reference may be provided in the middle portion of the bracket 81 in the longitudinal direction. In this case, the sensor side reference is, for example, the reference locking portion 153 shown in FIG. 15, and the bracket side reference is, for example, the locking hole 151 shown in FIG. Then, the first attachment engagement portion 42 engaged with the first engagement portion 86 is in the longitudinal direction of the bracket 81 with respect to the first engagement portion 86 while being engaged with the first engagement portion 86. The second attachment engagement portion 72 that is movable and engaged with the second engagement portion 152 remains in a state in which the second attachment engagement portion 152 is engaged with the second engagement portion 152 in the longitudinal direction of the bracket 81. It can be moved in the direction.

  In this way, when the hollow insulator 22 is fixed in order from the bracket side reference toward the first engagement portion 86 and the second engagement portion 152 provided at both ends in the longitudinal direction of the hollow insulator 22, A portion from the reference locking portion 153 that is the sensor side reference in the hollow insulator 22 to the first first mounting engagement portion 42, and the other one from the reference locking portion 153 that is the sensor side reference in the hollow insulator 22. 2 It is difficult to make a difference in the amount of attachment error in the longitudinal direction from the portion up to the attachment engagement portion 72. As a result, it is difficult for one first attachment engagement portion 42 and the other second attachment engagement portion 72 to differ in the amount of movement in the longitudinal direction with respect to the bracket 81. That is, the attachment error in the longitudinal direction of the hollow insulator 22 with respect to the bracket 81 is biased toward one of the first attachment engagement portion 42 and the second attachment engagement portion 72. Can be suppressed. Therefore, the amount of movement of the bracket 81 in the longitudinal direction relative to the first engagement portion 86 of the first attachment engagement portion 42 due to the attachment error in the longitudinal direction of the hollow insulator 22, and the first due to the attachment error in the longitudinal direction of the hollow insulator 22. 2 The amount of movement of the bracket 81 in the longitudinal direction relative to the second engagement portion 152 of the attachment engagement portion 72 can be reduced. As a result, the length in the longitudinal direction of the bracket 81 in the first engaging portion 86 and the second engaging portion 152 can be shortened.

  The sensor-side reference and the bracket-side reference are not limited to being engaged. The sensor side reference is a mark provided on the foreign object detection sensor 13, and the bracket side reference is the bracket 81 so that the mark provided on the foreign object detection sensor 13 as the sensor side reference is aligned in the longitudinal direction of the bracket 81. It may be a mark provided.

  When the bracket 81 has a plurality of curved portions that are curved, the bracket-side reference may be provided between the curved portions adjacent to each other in the longitudinal direction of the bracket 81. For example, in the case where the two bending portions 82 and 83 are provided as in the bracket 81 of the above embodiment, the bracket side reference is provided between the first bending portion 82 and the second bending portion 83. The foreign matter detection sensor 13 is a sensor that is aligned with the bracket-side reference and the longitudinal direction of the bracket 81 at a portion of the hollow insulator 22 that is fixed between the first bending portion 82 and the second bending portion 83. Set a side reference. Further, the first attachment engaging portion 42 can be moved in the longitudinal direction of the bracket 81 with respect to the first engaging portion 86 while being engaged with the first engaging portion 86, and the second engaging portion 87. The second attachment engagement portion 72 engaged with the second engagement portion 87 is configured to be movable in the longitudinal direction of the bracket 81 with respect to the second engagement portion 87. In this way, the following effects can be obtained. In general, when the hollow insulator 22 is fixed to the bracket 81 with the double-sided tape 91, the portion where the bracket 81 is curved tends to be displaced in the longitudinal direction with respect to the bracket 81. When the bracket side reference is provided between the first bending portion 82 and the second bending portion 83 adjacent to each other in the longitudinal direction of the bracket 81, the bracket side reference is provided at a position close to the two bending portions 82 and 83. It will be. For these reasons, a bracket side reference is provided between the first bending portion 82 and the second bending portion 83 adjacent to each other in the longitudinal direction of the bracket 81, and the first engagement portion 86 and the second engagement portion 86 on both sides from the bracket side reference are provided. By fixing the hollow insulator 22 in order toward the engaging portion 87, an attachment error in the longitudinal direction of the hollow insulator 22 with respect to the bracket 81 can be suppressed small. Therefore, the amount of movement of the bracket 81 in the longitudinal direction relative to the first engagement portion 86 of the first attachment engagement portion 42 due to the attachment error in the longitudinal direction of the hollow insulator 22 and the first due to the attachment error in the longitudinal direction of the hollow insulator 22. 2 The amount of movement of the bracket 81 in the longitudinal direction relative to the second engagement portion 87 of the attachment engagement portion 72 can be reduced. As a result, the length in the longitudinal direction of the bracket 81 at the first engaging portion 86 and the second engaging portion 87 can be shortened.

  In the above embodiment, the bracket 81 has two curved portions (the first curved portion 82 and the second curved portion 83). However, the number of curved portions of the bracket 81 may be one or may be three or more. In addition, the bracket 81 does not necessarily have a curved portion.

  In the above embodiment, the second attachment engagement portion 72 that is the sensor side reference is the second end portion that is the end portion of the hollow insulator 22 on the side where the lead wires 61 and 62 are connected to the electrode wires 23 and 24. 22f. However, the first attachment engagement portion 42 provided at the first end 22e of the hollow insulator 22 may be used as the sensor side reference. In this case, the first engagement portion 86 with which the first attachment engagement portion 42 is engaged is a bracket side reference that is aligned with the sensor side reference in the longitudinal direction of the bracket 81. The first attachment engagement portion 42 engaged with the first engagement portion 86 is positioned in the longitudinal direction of the first engagement portion 86 and the bracket 81 by contacting the bottom surface of the first engagement portion 86. To be combined. Further, the second attachment engagement portion 72 is movable in the longitudinal direction of the bracket 81 with respect to the second engagement portion 87 while being engaged with the second engagement portion 87.

  In the above embodiment, the holding member that holds the electrode wires 23 and 24 is configured by the hollow insulator 22. However, the holding member that holds the electrode wires 23 and 24 is not limited to the configuration of the above embodiment. For example, the holding member may be as shown in FIGS. In FIGS. 17 and 18, the same reference numerals are given to the same configurations as those in the above embodiment. The holding member 162 constituting the foreign object detection sensor 161 shown in FIGS. 17 and 18 includes a hollow insulator 22 and a protector 163 that holds the hollow insulator 22 inside. The protector 163 is made of an elastic material (rubber, elastomer, etc.) and has a long shape. The length of the protector 163 in the longitudinal direction is substantially equal to the length of the hollow insulator 22 in the longitudinal direction. The protector 163 has a cylindrical shape, and the sensor unit 21 is inserted therein. That is, the protector 163 holds the sensor part 21 inside, and thus holds the electrode wires 23 and 24 that are in contact with each other when the external force from the foreign substance is transmitted, together with the hollow insulator 22. Further, on the outer peripheral surface of the protector 163, a band-shaped sticking surface 163a extending in the longitudinal direction is formed. Further, as shown in FIG. 17, a first attachment engagement portion 164 is formed at one end portion of the protector 163 in the longitudinal direction (end portion on the first end portion 22 e side). The first attachment engaging portion 164 has a substantially bowl-like shape that extends from the sticking surface 163a perpendicularly to the sticking surface 163a at one end in the longitudinal direction of the protector 163 and then extends to the other end in the longitudinal direction of the protector 163. Yes. A portion on the distal end side of the first attachment engaging portion 164 extends in parallel with the attachment surface 163a, and a first engagement is provided between the portion on the distal end side of the first attachment engagement portion 164 and the attachment surface 163a. A concavity 164a is formed. As shown in FIG. 18, a second attachment engagement portion 165 is formed at the other end portion in the longitudinal direction of the protector 163 (the end portion on the second end portion 22 f side). The second attachment engagement portion 165 has a substantially bowl-like shape that extends from the sticking surface 163a perpendicularly to the sticking surface 163a at the other end in the longitudinal direction of the protector 163 and then extends to one end in the longitudinal direction of the protector 163. Yes. A portion on the distal end side of the second attachment engaging portion 165 extends in parallel with the attachment surface 163a, and a second engagement is provided between the portion on the distal end side of the second attachment engagement portion 165 and the attachment surface 163a. A concavity 165a is formed.

  The bracket 171 is formed with an adhesive surface 172 having a strip shape extending in the longitudinal direction. And as shown in FIG. 17, the 1st engaging part 173 is formed in the one end part (end part used as the upper end side of the door panel 5) of the longitudinal direction of this bracket 171. As shown in FIG. The first engaging portion 173 protrudes from the longitudinal end of the bracket 171 in the longitudinal direction of the bracket 171. The first engaging portion 173 is formed so as to extend the adhesive surface 172 in the longitudinal direction of the bracket 171. Furthermore, the length in the longitudinal direction of the bracket 171 in the first engaging portion 173 is formed longer than the depth of the first engaging recess 164a. As shown in FIG. 18, a second engagement portion 174 is formed at the other end portion in the longitudinal direction of the bracket 171 (the end portion on the lower end side of the door panel 5). The second engagement portion 174 protrudes in the longitudinal direction of the bracket 171 from the other end portion in the longitudinal direction of the bracket 171. The second engaging portion 174 is formed so as to extend the adhesive surface 172 in the longitudinal direction of the bracket 171.

  As shown in FIG. 17, such a foreign matter detection sensor 161 first performs a reference alignment process and inserts the first engagement portion 173 into the first engagement recess 164 a of the first attachment engagement portion 164. The first attachment engagement portion 164 is engaged with the first engagement portion 173. At this time, the end of the first engagement portion 173 is brought into contact with the bottom surface of the first engagement recess 164a, so that one end in the longitudinal direction of the protector 163 and one end in the longitudinal direction of the bracket 171 are connected to the bracket 171. Aligned in the longitudinal direction. That is, the first attachment engagement portion 164 is used as the sensor side reference, and the first engagement portion 173 is used as the bracket side reference. Note that the reference matching process of this example includes a part of the engagement process. Next, as shown in FIG. 18, the second attachment engagement portion 165 is performed by performing an engagement process and inserting the second engagement portion 174 into the second engagement recess 165 a of the second attachment engagement portion 165. Is engaged with the second engagement portion 174. The second attachment engagement portion 165 is movable in the longitudinal direction of the bracket 171 (left and right in FIG. 18) with respect to the second engagement portion 174 while being engaged with the second engagement portion 174. . Next, a fixing process is performed, and the protector is provided by the double-sided tape 91 interposed between the sticking surface 163a and the bracket 171 from the first engaging portion 173 which is the bracket side reference toward the second engaging portion 174. 163 is fixed to the bracket 171 in order. At this time, the second attachment engagement portion 165 moves in the longitudinal direction of the bracket 81 with respect to the second engagement portion 174 in accordance with the attachment error in the longitudinal direction of the protector 163. Even if it does in this way, the effect similar to (1) and (2) of the said embodiment can be acquired.

  -It may replace with the double-sided tape 91 of the said embodiment, and may use the double-sided tape 181 shown to Fig.19 (a). As shown in FIG. 19A, the double-sided tape 181 has a band shape, and its width is slightly narrower than the width of the sticking surface 22a. The double-sided tape 181 has a plurality of cut portions 182 at both ends in the width direction. Each cut portion 182 has a shape cut from an end portion in the width direction of the double-sided tape 181 toward a center portion in the width direction, and penetrates the double-sided tape 181 in the thickness direction. Further, each cut portion 182 has a width of the cut portion 182 (the length of the cut portion 182 in the direction along the longitudinal direction of the double-sided tape 181) narrows toward the center portion in the width direction of the double-sided tape 181. It has a triangular shape. In addition, at both ends of the double-sided tape 181 in the width direction, the plurality of cut portions 182 are formed at regular intervals along the longitudinal direction of the double-sided tape 181. Furthermore, the plurality of cut portions 182 formed at one end in the width direction of the double-sided tape 181 and the plurality of cut portions 182 formed at the other end in the width direction of the double-sided tape 181 are the same It is formed alternately along the longitudinal direction of the tape 181.

  In this way, as shown in FIG. 19B, when the hollow insulator 22 is curved according to the shape of the bonding surface 85 of the bracket 81, the double-sided tape 181 is accompanied by the curvature of the hollow insulator 22. By opening or closing the cut portion 182 in the longitudinal direction of the hollow insulator 22, it becomes easier to follow the curvature of the hollow insulator 22. In addition, since the double-sided tape 181 has the cut portion 182, the deformation of the double-sided tape 181 accompanying the curvature of the hollow insulator 22 is suppressed from being concentrated locally on the double-sided tape 181. Therefore, it is suppressed that the double-sided tape 181 peels from the sticking surface 22a or the double-sided tape 181 is wrinkled. Therefore, the double-sided tape 181 can stably adhere to both the sticking surface 22a and the adhesive surface 85. As a result, the hollow insulator 22 can be fixed to the bracket 81 more stably.

  Note that the cut portions 182 are not necessarily provided at a plurality of locations in the longitudinal direction of the double-sided tape 181. Further, the shape of the cut portion 182 is not limited to a triangular shape. The cut part 182 may be cut in the width direction at at least one place in the longitudinal direction of the double-sided tape 181. Even if it does in this way, the effect similar to the example shown in FIG. 19 can be acquired.

  In the above embodiment, the adhesive member that fixes the hollow insulator 22 interposed between the attachment surface 22 a and the bracket 81 to the bracket 81 is the double-sided tape 91. However, this adhesive member is not limited to the double-sided tape 91 but may be an adhesive or the like.

  In the above embodiment, the two electrode wires 23 and 24 are held inside the hollow insulator 22. However, the number of electrode wires held inside the hollow insulator 22 is not limited to this, and may be a plurality. For example, as illustrated in FIG. 20, the hollow insulator 22 may hold four electrode wires 191 to 194. These four electrode lines 191 to 194 are composed of a center electrode 25 and a conductive coating layer 26 in the same manner as the electrode lines 23 and 24 of the above embodiment. In the example shown in FIG. 20, the four electrode wires 191 to 194 extend spirally in the longitudinal direction of the hollow insulator 22 while being separated in the circumferential direction. Of the four electrode wires 191 to 194, two electrode wires 191 and 193 are electrically connected on the first end 22e side of the hollow insulator 22, and the remaining two electrode wires 192 are connected. , 194 are electrically connected on the first end 22e side of the hollow insulator 22. Furthermore, the electrode wire 192 and the electrode wire 193 are connected via a resistor 35 on the second end 22 f side of the hollow insulator 22. The electrode wire 191 is connected to the lead wire 61 on the second end portion 22f side of the hollow insulator 22, and the electrode wire 194 is connected to the lead wire 62 on the second end portion 22f side of the hollow insulator 22. Is done.

  In the above embodiment, the first attachment engagement portion 42 on the sensor side may be fixed so as not to move with respect to the first engagement portion 86 on the bracket 81 side. For example, in the example shown in FIG. 21, the first attachment engagement portion 42 and the first engagement portion 86 are fixed by the adhesive B. The step of fixing the first attachment engagement portion 42 (attachment engagement portion fixing step) includes an engagement step of engaging the first attachment engagement portion 42 with the first engagement portion 86, and the hollow insulator 22. This is performed after the fixing step of fixing to the bracket 81. For this reason, during the fixing step of fixing the hollow insulator 22 to the bracket 81, the first attachment engaging portion 42 can move in the longitudinal direction of the bracket 81 while being engaged with the first engaging portion 86. A mounting error in the longitudinal direction of the hollow insulator 22 can be absorbed by the movement of the first mounting engaging portion 42. According to this configuration, rattling that occurs between the first attachment engagement portion 42 and the first engagement portion 86 can be suppressed, whereby the first attachment engagement portion 42 and the vibration due to vehicle vibration or the like can be suppressed. Occurrence of abnormal noise generated in the first engagement portion 86 can be suppressed. Note that the second attachment engagement portion 72 and the second engagement portion 87 may also be fixed to each other with an adhesive or the like.

  In the above embodiment, the length of the first mounting engagement portion 42 is configured to be shorter than the length of the first engagement portion 86 in the longitudinal direction of the bracket 81, but is not particularly limited thereto. As shown in FIG. 22, the length of the first attachment engagement portion 42 may be configured to be longer than the length of the first engagement portion 86. In this configuration, the first attachment engagement portion 42 protrudes outward in the longitudinal direction from the first engagement portion 86, but the first engagement portion 86 is outside in the longitudinal direction (the side opposite to the longitudinal center portion of the bracket 81). ) In the longitudinal direction of the bracket 81 while being engaged with the first engagement portion 86. Therefore, the mounting error in the longitudinal direction of the hollow insulator 22 during the fixing process can be absorbed by the movement of the first mounting engaging portion 42.

  In the above embodiment, the hollow insulator 22 is fixed to the bracket 81 after the engaging step of engaging the first and second attachment engaging portions 42 and 72 with the first and second engaging portions 86 and 87, respectively. Although the fixing process is performed, the present invention is not limited to this. For example, in the configuration shown in FIGS. 12 and 13, after the hollow insulator 22 is fixed to the bracket 81 with the double-sided tape 91, the second attachment engagement portion 142 is inserted into the second engagement portion 132 to perform the second attachment. The engaging portion 142 and the second engaging portion 132 may be elastically engaged (see FIG. 23). At this time, since the second engagement portion 132 has a shape that allows the second attachment engagement portion 142 to move in the longitudinal direction, the second attachment engagement portion 142 can be engaged with the second engagement portion 132. The range is wide in the longitudinal direction. For this reason, also in the assembly procedure in which the engaging step is performed after the fixing step, the longitudinal mounting error caused when the hollow insulator 22 is fixed to the bracket 81 with the double-sided tape 91 is caused by the second mounting engaging portion. 142 and the second engaging portion 132 can absorb the water.

  Further, according to the above procedure, the fixing step of fixing the hollow insulator 22 to the bracket 81 with the double-sided tape 91 is engaged with the second mounting engaging portion 142 and the second engaging portion 132 before the engaging step. Therefore, the degree of freedom in fixing the hollow insulator 22 with the double-sided tape 91 can be maintained. Therefore, when the bracket 81 is not a simple shape such as a straight line but a complicated shape having a plurality of curved portions, the assembling property of the hollow insulator 22 can be effectively improved. Further, since the hollow insulator 22 is fixed before the engagement step, the handling of the second attachment engagement portion 142 (second terminal processing portion 51) in the engagement step is limited to some extent, but the flexibility is reduced. Since the second mounting engagement portion 142 having elastic deformation is elastically engaged with the second engagement portion 132, the second mounting engagement portion 142 and the second engagement portion 132 can be easily assembled. It becomes possible to do.

  In the example shown in FIG. 23, only the second attachment engaging portion 142 of the second attachment engaging portion 142 and the second engaging portion 132 is configured to be flexible and elastically deformable. However, you may comprise only the 2nd engaging part 132, or both so that elastic deformation is possible.

  In the above embodiment, in the fixing step, the double-sided tape 91 is adhered to the adhesive surface 85 across the entire length from the second attachment engagement portion 72 side to the first attachment engagement portion 42 side along the longitudinal direction. In addition to this, for example, the double-sided tape may have an intermittent configuration in the longitudinal direction (that is, a configuration in which the bonding surface 22a is also intermittent). That is, you may stick with the some double-sided tape arranged along a longitudinal direction.

  -In above-mentioned embodiment, although the sticking surface 22a of the sensor part 21 was provided in the hollow insulator 22, it is not specifically limited to this. For example, when providing an interposition member for offsetting the height of the sensor unit 21 (the height in the direction perpendicular to the adhesive surface 85 of the bracket 81) between the hollow insulator 22 and the adhesive surface 85 of the bracket 81, The interposed member and the hollow insulator 22 are fixed to each other with, for example, a double-sided tape or an adhesive, and constitute a holding member of the sensor unit 21. Then, the interposition member is fixed to the adhesive surface 85 of the bracket 81 with the double-sided tape 91. In this way, the sticking surface that is fixed to the adhesive surface 85 by the double-sided tape 91 may be provided on the interposed member that constitutes the holding member with the hollow insulator 22.

  In the above embodiment, each of the electrode wires 23 and 24 is formed by twisting conductive thin wires and has a flexible center electrode 25 and a cylindrical shape that has conductivity and elasticity and covers the outer periphery of the center electrode 25. And a conductive coating layer 26. However, each of the electrode wires 23 and 24 may be a single metal wire having flexibility.

  In the above embodiment, the foreign object detection sensor 13 is disposed on the peripheral edge of the door panel 5. However, the foreign matter detection sensor 13 may be disposed on the peripheral edge of the rear opening 4 facing the peripheral edge of the door panel 5. The foreign matter detection sensor 13 is not limited to the foreign matter detection device 11 provided in the electric back door device 2, and the foreign matter provided in the electric slide door device that opens and closes the entrance / exit provided on the side surface of the vehicle by sliding the door panel. It may be used in a detection device. The foreign matter detection sensor 13 is used in a device for detecting contact of foreign matter, in addition to being used in a foreign matter detection device provided in a door opening and closing device that is opened and closed by moving a door panel by a driving force such as a motor. May be.
