  For example, the foreign object detection device described in Patent Document 1 includes a long foreign object detection sensor that detects the foreign object by being elastically deformed by an external force applied from the foreign object. The foreign object detection sensor is held by a long protector made of a rubber material.

However, since the protector described in Patent Document 1 has a complicated shape such as embedding a cored bar in a rubber material, there is a problem that the manufacturing cost increases.
On the other hand, if the foreign object detection sensor is attached to the door panel using a double-sided tape instead of the protector, the manufacturing cost can be kept low. However, the attachment location (that is, the peripheral edge of the door panel, etc.) where the foreign object detection sensor is attached in the vehicle may be non-linear, such as curved. If the foreign object detection sensor is bent according to the shape of the installation location, the double-sided tape cannot follow the curvature of the foreign object detection sensor, and the double-sided tape may be peeled off from the foreign object detection sensor, or the double-sided tape may be wrinkled. There was a problem to do. Therefore, it has been difficult to stably attach the foreign object detection sensor to the door panel.

This makes it easier to follow the curvature of the foreign object detection sensor. Moreover, since the double-sided tape has a cut portion, the deformation of the double-sided tape accompanying the curvature of the foreign matter detection sensor is suppressed from being concentrated locally on the double-sided tape. Therefore, since the double-sided tape is prevented from peeling off from the sticking surface or the double-sided tape is wrinkled, the first adhesive surface is stable on the sticking surface and the second adhesive surface is stable on the mounting surface. It can adhere. For these reasons, the foreign object detection sensor can be attached to the installation location stably and inexpensively.

Further, the width of the mounting recess 22 is constant along the longitudinal direction of the mounting recess 22. The bottom surface of the mounting recess 22 is a band-shaped mounting surface 23 extending along the longitudinal direction of the bracket 21. Since the mounting recess 22 is non-linear, the mounting surface 23 is also non-linear like the mounting recess 22. In addition, the inner side surface (the inner side surface on the right side in FIG. 3) far from the peripheral edge of the door panel 5 among the two inner side surfaces in the width direction of the mounting recess 22 is a positioning surface 24 that is perpendicular to the mounting surface 23. The positioning surface 24 is formed to have a longer length from the mounting surface 23 than the inner side surface (the inner side surface on the left side in FIG. 3) closer to the peripheral edge of the door panel 5 among the both inner side surfaces in the width direction of the mounting recess 22. ing.

  As shown in FIGS. 3 and 4, the foreign object detection sensor 31 has a long string shape. The long hollow insulator 32 constituting the foreign object detection sensor 31 is formed of an elastically deformable insulator (soft resin material, elastomer, or the like).

  On the outer peripheral surface of the hollow insulator 32, a band-like sticking surface 32a extending along the longitudinal direction of the hollow insulator 32 is formed. The sticking surface 32a is linear in a cross section orthogonal to the longitudinal direction of the hollow insulator 32 (ie, the cross section shown in FIG. 3). Further, the sticking surface 32 a is formed to be slightly narrower than the mounting surface 23 and is formed to have a constant width along the longitudinal direction of the hollow insulator 32. A pair of side surfaces 32b and 32c that are parallel to each other are formed on both sides of the outer peripheral surface of the hollow insulator 32 in the width direction of the sticking surface 32a. The side surfaces 32 b and 32 c are perpendicular to the sticking surface 32 a and extend along the longitudinal direction of the hollow insulator 32. Further, on the outer peripheral surface of the hollow insulator 32, an arcuate arc surface 32d is formed at a portion opposite to the attaching surface 32a with the pair of side surfaces 32b and 32c interposed therebetween. The circular arc surface 32d is formed so as to protrude to the opposite side of the sticking surface 32a and to connect the one side surface 32b and the other side surface 32c.

  Further, a hollow hole 32 e extending along the longitudinal direction of the hollow insulator 32 is formed inside the hollow insulator 32. By having the hollow hole 32e, the hollow insulator 32 has a hollow shape. In addition, four electrode wires 33 to 36 held by the hollow insulator 32 are arranged to be spaced apart from each other inside the hollow insulator 32. Each of the electrode wires 33 to 36 includes a flexible central electrode 37 formed by twisting conductive thin wires, and a cylindrical conductive coating layer 38 that has conductivity and elasticity and covers the outer periphery of the central electrode 37. It is composed of The electrode lines 33 to 36 are arranged at equal angular intervals in the circumferential direction (90 ° intervals in the present embodiment) inside the hollow insulator 32 and between the electrode lines 33 to 36 adjacent in the circumferential direction. While maintaining a constant interval, the hollow insulator 32 extends in a spiral shape in the longitudinal direction. Further, each of the electrode wires 33 to 36 is held by the hollow insulator 32 by being partially embedded in the hollow insulator 32 inside the hollow insulator 32.

  As shown in FIG. 2, the electrode wire 33 and the electrode wire 35 are electrically connected to each other at one end in the longitudinal direction (the left end in FIG. 2), and the electrode wire 34 and the electrode wire 36 are also connected to one end in the longitudinal direction. (Left end in FIG. 2) are connected to each other and conducted. The other ends of the electrode wire 35 and the electrode wire 36 in the longitudinal direction are electrically connected via a resistor 39. Furthermore, the other end of the electrode wire 33 in the longitudinal direction is electrically connected to the energization detection unit 41, and the other end of the electrode wire 34 is connected to the ground GND (that is, grounded to the vehicle body 3).

  As shown in FIG. 3, the foreign matter detection sensor 31 as described above is attached to the bracket 21 with a double-sided tape 51. As shown in FIG. 1, the attachment position of the foreign object detection sensor 31 of the present embodiment is a bracket 21 fixed to the peripheral portion of the door panel 5, and the foreign object detection sensor 31 is connected to the door panel 5 via the bracket 21. It is fixed to the peripheral part.

  As shown in FIGS. 3 and 5 (a), the double-sided tape 51 has a band shape, and its width is slightly narrower than the width of the sticking surface 32a. 3 and 5, fine dots are attached to the double-sided tape 51 in order to make the shape of the double-sided tape 51 easy to understand. The double-sided tape 51 has a plurality of cut portions 52 at both ends in the width direction. Each cut portion 52 has a shape that is cut from the end portion in the width direction of the double-sided tape 51 toward the center portion in the width direction, and penetrates the double-sided tape 51 in the thickness direction. In addition, each cut portion 52 becomes narrower in width toward the center in the width direction of the double-sided tape 51 (the length of the cut portion 52 in the direction along the longitudinal direction of the double-sided tape 51). It has a triangular shape. Further, at both ends in the width direction of the double-sided tape 51, the plurality of cut portions 52 are formed at regular intervals along the longitudinal direction of the double-sided tape 51 from one end to the other end in the longitudinal direction of the double-sided tape 51. Furthermore, the plurality of cut portions 52 formed at one end in the width direction of the double-sided tape 51 and the plurality of cut portions 52 formed at the other end in the width direction of the double-sided tape 51 are the same It is formed alternately along the longitudinal direction of the tape 51. In this double-sided tape 51, one surface in the thickness direction (upper surface in FIG. 3) is a first adhesive surface 51a, and the other surface in the thickness direction (lower surface in FIG. 3) is a second adhesive surface 51b. .

Here, the operation of the attachment structure of the foreign matter detection sensor 31 of the present embodiment will be described together with the procedure for attaching the foreign matter detection sensor 31 to the bracket 21.
When attaching the foreign object detection sensor 31 to the bracket 21, first, the first adhesive surface 51 a of the double-sided tape 51 is attached to the attachment surface 32 a of the hollow insulator 32. At this time, the double-sided tape 51 is stuck to the sticking surface 32 a so that the longitudinal direction thereof is along the longitudinal direction of the hollow insulator 32. Thereafter, the second adhesive surface 51 b of the double-sided tape 51 is attached to the attachment surface 23 of the bracket 21, whereby the foreign object detection sensor 31 is attached to the bracket 21 by the double-sided tape 51. At this time, the foreign object detection sensor 31 positions the mounting surface 23 in the width direction with respect to the bracket 21 by bringing the side surface 32 b of the hollow insulator 32 into contact with the positioning surface 24 of the bracket 21. The foreign matter detection sensor 31 is attached to the bracket 21 with a double-sided tape 51 while being partially curved according to the shape of the non-linear mounting surface 23. As shown in FIG. 5B, when the foreign object detection sensor 31 is curved according to the shape of the mounting surface 23 provided on the bracket 21, the double-sided tape 51 is cut into the cut portion along with the curvature of the foreign object detection sensor 31. 52 opens or closes in the longitudinal direction of the foreign object detection sensor 31 to follow the curvature of the foreign object detection sensor 31. In addition, each portion between the cut portion 52 and the cut portion 52 of the double-sided tape 51 can be slightly deformed. Therefore, the deformation of the double-sided tape 51 caused by bending the foreign object detection sensor 31 is suppressed from being concentrated on the local area of the double-sided tape 51. Therefore, even if the foreign object detection sensor 31 is curved, it is possible to prevent the double-sided tape 51 from being peeled off from the sticking surface 32a or causing wrinkles on the double-sided tape 51.

  As shown in FIG. 2, the energization detection unit 41 is provided at the other end in the longitudinal direction of the foreign object detection sensor 31 (the end on the right side in FIG. 2 where the resistor 39 is provided). At the same time, a current is supplied to the electrode wire 33. As shown in FIGS. 2 and 3, in a normal state where an external force such as a pressing force is not applied to the foreign object detection sensor 31, the current supplied from the energization detection unit 41 to the electrode wire 33 is the electrode wire 35. And flows to the electrode wires 36 and 34 via the resistor 39. On the other hand, as shown in FIGS. 2 and 6, when an external force (see arrow α in FIG. 6) that crushes the foreign object detection sensor 31 is applied, the hollow insulator 32 at the site where the external force is applied is elastically deformed. As the hollow insulator 32 is elastically deformed, the electrode wires 33 to 36 are bent, and at least one of the electrode wires 33 and 35 and at least one of the electrode wires 34 and 36 are in contact with each other. Shorted. Then, the current supplied from the energization detection unit 41 to the electrode wire 33 flows through the electrode wires 36 and 34 without passing through the resistor 39. Therefore, for example, when a current is supplied to the electrode wire 33 at a constant voltage, the current value changes. Therefore, the energization detection unit 41 detects the foreign object by detecting the change in the current value at this time. A foreign object that has contacted the sensor 31 is detected. And if the electricity supply detection part 41 detects the change of this electric current value, ie, detects the foreign material which contacted the foreign material detection sensor 31, it will output a foreign material detection signal to the door ECU61 mentioned later. In addition, when the external force with respect to the foreign material detection sensor 31 is removed, the hollow insulator 32 is restored, and the electrode wires 33 to 36 are also restored to be in a non-conductive state.

  As shown in FIGS. 1 and 2, the electric back door device 2 includes a door ECU 61 that controls an opening / closing operation of the door panel 5 by the actuator 6 inside the door panel 5. The door ECU 61 includes a ROM (Read only Memory), a RAM (Random access Memory), and the like, has a function as a microcomputer, and is supplied with power from a battery (not shown) of the vehicle 1. The door ECU 61 supplies a current to the energization detection unit 41 that is electrically connected to the door ECU 61. The door ECU 61 controls the actuator 6 based on various signals input from the operation switch 9, the position detection device 8, the energization detection unit 41, and the like.

Next, the operation of the electric back door device 2 configured as described above will be comprehensively described with reference to FIGS. 1 and 2.
When an open signal is input from the operation switch 9, the door ECU 61 drives the actuator 6 to open the door panel 5. The door ECU 61 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 61 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 open position, the door ECU 61 stops the actuator 6.

  On the other hand, when a close signal is input from the operation switch 9, the door ECU 61 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 61 stops the actuator 6. When a foreign object comes into contact with the foreign object detection sensor 31 and an external force is applied to the foreign object detection sensor 31 during the closing operation of the door panel 5, the hollow insulator 32 is elastically deformed in the foreign object detection sensor 31, thereby At least one of the electrode wires 33 and 35 and at least one of the electrode wires 34 and 36 are brought into contact with each other and are short-circuited. As a result, since the current value of the current supplied to the electrode wire 33 changes, the energization detection unit 41 outputs a foreign object detection signal to the door ECU 61. When the foreign object detection signal is input, the door ECU 61 reverses the actuator 6 to open the door panel 5 by a predetermined amount and then stops the actuator 6.

As described above, the present embodiment has the following effects.
(1) The foreign matter detection sensor 31 is attached to the bracket 21 fixed to the peripheral portion of the door panel 5 with a double-sided tape 51 that is cheaper than the protector without using a protector as in the prior art. When the foreign object detection sensor 31 is curved in accordance with the shape of the mounting surface 23 provided on the bracket 21, the double-sided tape 51 has a cut portion 52 in the longitudinal direction of the foreign object detection sensor 31 along with the curvature of the foreign object detection sensor 31. By opening or closing in the direction, it becomes easier to follow the curvature of the foreign object detection sensor 31. In addition, since the double-sided tape 51 has the cut portion 52, the deformation of the double-sided tape 51 accompanying the curvature of the foreign object detection sensor 31 is suppressed from being concentrated on the local area of the double-sided tape 51. Therefore, since the double-sided tape 51 is prevented from peeling off from the sticking surface 32a or wrinkles are generated on the double-sided tape 51, the first adhesive surface 51a is attached to the sticking surface 32a and the second adhesive surface 51b is attached. Each can be stably adhered to the surface 23. Therefore, the foreign object detection sensor 31 can be attached to the bracket 21 fixed to the peripheral edge of the door panel 5 at a low cost and stably.

  (2) The cut portion 52 corresponds to a portion of the double-sided tape 51 corresponding to a portion where the foreign object detection sensor 31 is curved according to the shape of the mounting surface 23, that is, a portion where the foreign object detection sensor 31 is attached linearly. The double-sided tape 51 is also formed in a portion where the double-sided tape 51 is greatly pulled or contracted compared to the portion. Therefore, it is possible to effectively suppress the double-sided tape 51 from being peeled off from the sticking surface 32a or the double-sided tape 51 being wrinkled at the portion where the foreign object detection sensor 31 is curved. Therefore, the first adhesive surface 51a can be more stably adhered to the attachment surface 32a and the second adhesive surface 51b can be more stably adhered to the attachment surface 23, and the foreign object detection sensor 31 can be more stably attached to the bracket 21. it can.

  (3) The hollow insulator 32 on which the sticking surface 32 a is formed has a hollow shape, and the four electrode wires 33 to 36 provided inside the hollow insulator 32 are arranged in the longitudinal direction of the hollow insulator 32. It extends in a spiral. Therefore, the foreign object detection sensor 31 is configured to be easily bent. Accordingly, the foreign object detection sensor 31 is stably attached to the bracket 21 by the double-sided tape 51 in a curved state.

  (4) Since the foreign object detection sensor 31 can be attached to the bracket 21 at a low cost, the manufacturing cost of the foreign object detection device 11 can be reduced. Further, since the foreign object detection sensor 31 is stably attached to the bracket 21 by the double-sided tape 51, when an external force is applied to the foreign object detection sensor 31 from the foreign object, it can be stably elastically deformed. Accordingly, it is possible to suppress a decrease in foreign matter detection sensitivity.

  (5) Conventionally, since the mounting surface at the mounting location is curved with a large curvature, the double-sided tape cannot follow the curvature of the foreign matter detection sensor, and a plurality of portions are avoided so as to avoid a curved portion with a large curvature on the mounting surface. It is possible to configure a single foreign object detection sensor that has been divided and attached to a book. And when attaching one foreign substance detection sensor 31 over the whole attachment surface, a manufacturing cost can be reduced compared with the case where multiple foreign substance detection sensors 31 are attached. Furthermore, since the foreign object detection sensor 31 is also disposed in a portion where the mounting surface is curved with a large curvature, contact of the foreign material can be detected even in a portion where the mounting surface is curved with a large curvature. .

In addition, you may change embodiment of this invention as follows.
In the above embodiment, the foreign object detector 11 is provided in the electric back door device 2 that electrically opens and closes the door panel 5 that opens and closes the rear opening 4 provided in the rear portion of the vehicle 1.

  In the above embodiment, the foreign object detection sensor 31 is attached to the peripheral edge of the door panel 5 that faces the peripheral edge of the rear opening 4 via the bracket 21. However, the foreign object detection sensor 31 may be attached to a portion of the peripheral edge of the rear opening 4 that faces the peripheral edge of the door panel 5. In this case, the part facing the peripheral part of the door panel 5 in the peripheral part of the rear opening 4 becomes an attachment place, and the attachment surface is provided in this part.

  In the above embodiment, the energization detection unit 41 supplies a current to the electrode wire 33 at a constant voltage, and outputs a foreign object detection signal when detecting a change in current value caused by the contact between the electrode wires 33 to 36. However, the energization detection unit 41 may be configured to output a foreign object detection signal when detecting a change in voltage value caused by contact between the electrode wires 33 to 36.

  In the above embodiment, the plurality of cut portions 52 formed at one end portion in the width direction of the double-sided tape 51 and the plurality of cut portions 52 formed at the other end portion in the width direction of the double-sided tape 51 Are formed alternately along the longitudinal direction of the double-sided tape 51. However, as shown in FIG. 7A, the plurality of cut portions 52 formed at one end in the width direction of the double-sided tape 51 and the other end in the width direction of the double-sided tape 51 are formed. The plurality of notches 52 may be formed adjacent to each other in the width direction of the double-sided tape 51. Even if it does in this way, as shown in FIG.7 (b), when the foreign material detection sensor 31 is curved according to the shape of the attachment surface 23, the double-sided tape 51 will be cut | disconnected by the curvature of the foreign material detection sensor 31. 52 opens or closes in the longitudinal direction of the foreign object detection sensor 31 to follow the curvature of the foreign object detection sensor 31. In addition, each portion between the cut portion 52 and the cut portion 52 of the double-sided tape 51 can be slightly deformed. Therefore, the same effect as the above embodiment can be obtained.

  -The shape and number of the notch | incision part formed in the double-sided tape 51 are not restricted to the shape and number of the said embodiment. The cut portion only needs to be cut in the width direction of the double-sided tape 51 at least at one place in the longitudinal direction of the double-sided tape 51. For example, in the example shown in FIG. 8A, the plurality of cut portions 53 formed at both end portions in the width direction of the double-sided tape 51 are directed from the end portions in the width direction of the double-sided tape 51 toward the center portion in the width direction. It has a cut shape and penetrates the double-sided tape 51 in the thickness direction. Each cut portion 53 has a rectangular shape as viewed from the thickness direction of the double-sided tape 51. Further, at both ends in the width direction of the double-sided tape 51, the plurality of cut portions 53 are formed at regular intervals along the longitudinal direction of the double-sided tape 51 from one end to the other end in the longitudinal direction of the double-sided tape 51. Furthermore, the plurality of cut portions 53 formed at one end in the width direction of the double-sided tape 51 and the plurality of cut portions 53 formed at the other end in the width direction of the double-sided tape 51 are the same It is formed alternately along the longitudinal direction of the tape 51.

  Even if it does in this way, as shown in FIG.8 (b), when the foreign material detection sensor 31 is curved according to the shape of the attachment surface 23, the double-sided tape 51 will be cut | disconnected in accordance with the curvature of the foreign material detection sensor 31. When 53 is opened or closed in the longitudinal direction of the foreign object detection sensor 31, it follows the curvature of the foreign object detection sensor 31. In addition, each portion between the cut portion 54 and the cut portion 54 of the double-sided tape 51 can be slightly deformed. Therefore, the deformation of the double-sided tape 51 caused by bending the foreign object detection sensor 31 is suppressed from being concentrated on the local area of the double-sided tape 51. Therefore, even if the foreign object detection sensor 31 is curved, it is possible to prevent the double-sided tape 51 from being peeled off from the sticking surface 32a or causing wrinkles on the double-sided tape 51. Therefore, the same effect as the above embodiment can be obtained. As shown in FIG. 9, a plurality of cuts 53 formed at one end of the double-sided tape 51 in the width direction and a plurality of cuts formed at the other end of the double-sided tape 51 in the width direction. The part 53 may be formed so as to be adjacent to each other in the width direction of the double-sided tape 51.

  In the example shown in FIG. 10, the cut portion 54 is formed only in a portion of the double-sided tape 51 corresponding to (attached to) the portion where the foreign object detection sensor 31 is curved according to the shape of the mounting surface 23. ing. A plurality of cut portions 54 (four in the example shown in FIG. 10) are formed in a portion corresponding to a portion where the foreign object detection sensor 31 is curved in the double-sided tape 51. Each notch 54 crosses the double-sided tape 51 in the width direction of the double-sided tape 51 and divides the double-sided tape 51 in the longitudinal direction. Even if it does in this way, the effect similar to the effect of the said embodiment can be acquired. Furthermore, since the cut portion 54 is formed only in a portion of the double-sided tape 51 corresponding to a portion where the foreign matter detection sensor 31 is curved according to the shape of the mounting surface 23, the foreign matter detection sensor 31 in the double-sided tape 51. The cut portion 54 is not formed in a portion corresponding to the portion to which is attached linearly. Therefore, in the portion where the foreign object detection sensor 31 is attached in a straight line, the sticking surface 32a, the attachment surface 23, and the double-sided tape 51 are bonded in a wider area, so that the foreign object detection sensor 31 is more stably attached to the bracket 21. Can be attached. Moreover, since the cut portion 54 crosses the double-sided tape 51 in the width direction of the double-sided tape 51 and divides the double-sided tape 51 in the longitudinal direction, the foreign matter detection sensor 31 can be curved in any direction. It can suppress that double-sided tape 51 peels from the sticking surface 32a, or a wrinkle arises in double-sided tape 51. FIG. Furthermore, compared with the case where the cut portion does not divide the double-sided tape 51 in the longitudinal direction, the double-sided tape 51 may be peeled off from the sticking surface 32a or the double-sided tape 51 may be wrinkled even if the foreign object detection sensor 31 is curved more greatly. It is hard to do.

  Moreover, in the example shown to Fig.11 (a), the notch part 55 corresponds to the part in which the foreign material detection sensor 31 is curved according to the shape of the attachment surface 23 in the double-sided tape 51 (it sticks). Only formed. A plurality of cut portions 55 (four in the example shown in FIG. 11A) are formed in a portion corresponding to a portion where the foreign object detection sensor 31 is curved in the double-sided tape 51. Further, each cut portion 55 crosses the double-sided tape 51 in the width direction of the double-sided tape 51 and divides the double-sided tape 51 in the longitudinal direction. Further, each cut portion 55 has a width (in the longitudinal direction of the double-sided tape 51) as it goes from the outer portion to the inner portion of the curved portion of the foreign matter detection sensor 31 when the foreign matter detection sensor 31 is curved. The width of the cut portion 55 in the extending direction is widened.

  Even if it does in this way, as shown in FIG.11 (b), when the foreign material detection sensor 31 is curved according to the shape of the attachment surface 23, the double-sided tape 51 will be cut | disconnected in accordance with the curvature of the foreign material detection sensor 31. 52 opens or closes in the longitudinal direction of the foreign object detection sensor 31 to follow the curvature of the foreign object detection sensor 31. In addition, each portion between the cut portion 55 and the cut portion 55 of the double-sided tape 51 can be slightly deformed. Therefore, the deformation of the double-sided tape 51 caused by bending the foreign object detection sensor 31 is suppressed from being concentrated on the local area of the double-sided tape 51. Therefore, even if the foreign object detection sensor 31 is curved, it is possible to prevent the double-sided tape 51 from being peeled off from the sticking surface 32a or causing wrinkles on the double-sided tape 51. Therefore, the same effect as that of the above embodiment can be obtained. Moreover, the same effect as the example shown in FIG. 10 can be acquired. Furthermore, in the curved portion where the foreign object detection sensor 31 is curved, the deformation amount of the double-sided tape 51 at the end portion closer to the inside of the curved portion of both ends in the width direction of the double-sided tape 51 can be further reduced. Accordingly, it is possible to further suppress wrinkling of the double-sided tape 51 at the curved portion where the foreign object detection sensor 31 is curved.

  In the example shown in FIGS. 10 and 11, the cut portions 54 and 55 may be formed at predetermined intervals along the longitudinal direction of the double-sided tape 51 from one end to the other end in the longitudinal direction of the double-sided tape 51.

  In the above embodiment, at both ends in the width direction of the double-sided tape 51, the plurality of cut portions 52 are formed at regular intervals along the longitudinal direction of the double-sided tape 51 from one end to the other end in the longitudinal direction of the double-sided tape 51. Has been. However, the cut portion 52 may be formed only in a portion of the double-sided tape 51 corresponding to (attached to) the portion where the foreign object detection sensor 31 is curved according to the shape of the mounting surface 23. In this way, in the part where the foreign object detection sensor 31 is attached in a straight line, the sticking surface 32a, the attachment surface 23, and the double-sided tape 51 are bonded in a wider area, so the foreign object detection sensor 31 is further attached to the bracket 21. Can be attached stably.

  -As long as the sticking surface 32a is formed in the outer peripheral surface of the hollow insulator 32, the shape of parts other than the sticking surface 32a is not restricted to the shape of the said embodiment. For example, the outer peripheral surface of the hollow insulator 32 may be formed in a polygonal cylindrical shape.

  In the above embodiment, the foreign object detection sensor 31 is attached to the peripheral edge portion of the door panel 5 via the bracket 21. However, the foreign matter detection sensor 31 may be directly attached to the peripheral portion of the door panel 5 with the double-sided tape 51. In this case, the peripheral portion of the door panel 5 is a place where the foreign object detection sensor 31 is attached, and an attachment surface is provided on the peripheral portion of the door panel 5.

  In the above embodiment, the foreign object detection sensor 31 includes four electrode wires 33 to 36. However, it is sufficient that at least two electrode wires are provided in the foreign object detection sensor 31, and for example, six electrode wires may be provided. Further, the electrode wires 33 to 36 do not necessarily have to be spiral as long as they are spaced apart from each other inside the hollow insulator 32.

The electrode wires 33 to 36 may be single wires made of annealed copper. Further, the electrode lines 33 to 36 may be strip-shaped.
The foreign object detection sensor 31 may be configured not only to detect a foreign object in contact with the foreign object detection sensor 31 by elastic deformation but also to detect a capacitance between adjacent foreign objects. In this case, the foreign object detection device 11 detects a foreign object close to the foreign object detection sensor 31 based on the capacitance detected using the foreign object detection sensor 31.
