The pair of pressing parts 43 and the first insertion part 42b folded in this way pass through (through) the through hole 26 while being slightly elastically deformed. Then, as shown in FIG. 5A, the pair of pressing portions 43 is restored in the holding recess 23 and separated from the first insertion portion 42 b, and the contact portions 43 a at the distal ends of the pair of pressing portions 43 are The pressing surfaces 25 on both sides in the width direction of the through hole 26 are in press contact with each other. Further, when the pair of pressing portions 43 passes through the through hole 26, the fitting portion 42a is fitted into the through hole 26, and the outer peripheral surface 32a of the hollow insulator 32 is received on both sides in the width direction of the fitting portion 42a. It contacts the surfaces 27a and 27b. As a result, the pair of pressing portions 43 that press the pressing surface 25 and the hollow insulator 32 of the foreign object detection sensor 31 allow the portion between the receiving surfaces 27a and 27b and the pressing surface 25 in the holding portion 22 to pass through. 26 is sandwiched from both sides in the penetration direction. Accordingly, the foreign object detection sensor 31 is fixed to the bracket 12 by the support portion 41. That is, the sensor wire 13 is fixed to the bracket 12. As described above, the foreign matter detection sensor 31 is configured such that the bracket 12 is sandwiched from both sides in the penetration direction of the through hole 26 by the pair of pressing portions 43 that press the pressing surface 25 and the hollow insulator 32 of the foreign matter detection sensor 31. Is stably fixed to the bracket 12.

  Further, the foreign matter detection sensor 31 fixed to the bracket 12 is exposed to the outside at a range of about 270 ° opposite to the holding portion 22 (receiving surfaces 27a, 27b), and this exposed range is the foreign matter detection sensor. This is a detection range in which a foreign object X (see FIG. 8) in contact with 31 can be detected. In this detection range, in the range where the external force applied to the foreign object detection sensor 31 passes through the radial center of the foreign object detection sensor 31 toward the receiving surface 27a or the receiving surface 27b, the external force is applied to the foreign object detection sensor 31. Can be received by the receiving surface 27a or the receiving surface 27b. Therefore, the foreign object detection sensor 31 is easily deformed by being sandwiched between the foreign object X and the receiving surface 27a or the receiving surface 27b.

  As shown in FIG. 2, the energization detection unit 14 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 5A, in a normal state where no external force such as a pressing force is applied to the foreign object detection sensor 31, the current supplied from the energization detection unit 14 to the electrode wire 33 is It passes through the electrode line 35 and flows through the resistor 39 to the electrode lines 34 and 36. On the other hand, as shown in FIGS. 2 and 8, when an external force that crushes the foreign object detection sensor 31 in the diametrical direction is applied, the hollow insulator 32 at the site where the external force is applied is elastically deformed and the hollow insulator 32 is also deformed. The electrode wires 33 to 36 are bent in accordance with the elastic deformation, and at least one electrode wire of the electrode wires 33 and 35 and at least one electrode wire of the electrode wires 34 and 36 are contacted and short-circuited. Then, the current supplied from the energization detection unit 14 to the electrode wire 33 flows through the electrode wires 34 and 36 without passing through the resistor 39. Therefore, for example, when the current is supplied to the electrode wire 33 at a constant voltage, the current value changes. Therefore, the energization detection unit 14 detects the foreign object by detecting the change in the current value at this time. The foreign object X that has contacted the sensor 31 is detected. And if the electricity supply detection part 14 detects the change of this electric current value, ie, detects the foreign material X which contacted the foreign material detection sensor 31, it will output a foreign material detection signal to the door ECU51 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 and become non-conductive.

  As shown in FIGS. 1 and 2, the electric back door device 2 includes a door ECU 51 that controls the opening / closing operation of the door panel 5 by the actuator 6 inside the door panel 5. The door ECU 51 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 51 supplies a current to the energization detection unit 14 that is electrically connected to the door ECU 51. The door ECU 51 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 with reference to FIGS. 1 and 2.
When an open signal is input from the operation switch 9, the door ECU 51 drives the actuator 6 to open the door panel 5. The door ECU 51 recognizes the rotation 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 51 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 where the rear opening 4 is completely opened, the door ECU 51 stops the actuator 6.

  On the other hand, when a close signal is input from the operation switch 9, the door ECU 51 drives the actuator 6 to close the door panel 5. Then, when the door panel 5 is disposed at the fully closed position where the rear opening 4 is completely closed, the door ECU 51 stops the actuator 6. When the foreign object X 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. At least one of the wires 33 and 35 and at least one of the electrode wires 34 and 36 are in contact with each other and are short-circuited. As a result, since the current value of the current supplied to the electrode wire 33 is changed, the energization detection unit 14 outputs a foreign object detection signal to the door ECU 51. When the foreign object detection signal is input, the door ECU 51 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) Since the bracket 12 is sandwiched from both sides in the penetration direction of the through hole 26 by the foreign matter detection sensor 31 and the pressing portion 43 of the support portion 41 penetrating the through hole 26, the weight is reduced by being formed from resin. The foreign object detection sensor 31 can be stably fixed to the bracket 12. Therefore, the responsiveness of the elastic deformation of the foreign object detection sensor 31 due to the external force applied from the foreign object X can be improved.

  (2) The bracket 12 has receiving surfaces 27 a and 27 b that contact the outer peripheral surface of the foreign object detection sensor 31 (that is, the outer peripheral surface 32 a of the hollow insulator 32) and receive external force via the foreign object detection sensor 31. Since the posture of the foreign object detection sensor 31 is easily stabilized by the receiving surfaces 27a and 27b, the foreign object detection sensor 31 can be more stably fixed to the resin bracket 12. Further, when an external force is applied from the foreign object X to the foreign object detection sensor 31, the external force can also be received by the receiving surfaces 27 a and 27 b via the foreign object detection sensor 31. When the external force applied from the foreign object X is also received by the surfaces 27a and 27b, the foreign object detection sensor 31 may be displaced with respect to the bracket 12 by being supported by the receiving surfaces 27a and 27b. It is suppressed and can be elastically deformed stably at the position fixed to the bracket 12. Furthermore, the foreign object detection sensor 31 is easily elastically deformed by an external force from the foreign object X by being sandwiched between the foreign object X and the receiving surfaces 27a and 27b, so that the detection sensitivity of the foreign object X by the foreign object detection sensor 31 is improved. Can do.

  (3) When the cylindrical outer peripheral surface of the foreign object detection sensor 31 (that is, the outer peripheral surface 32a of the hollow insulator 32) has an arc shape with the same curvature, the receiving surfaces 27a and 27b come into contact with the outer peripheral surface of the foreign object detection sensor 31. The foreign object detection sensor 31 is more stably fixed to the bracket 12. Further, the foreign object detection sensor 31 is further prevented from being displaced with respect to the bracket 12 by an external force applied from the foreign object X. Furthermore, the strength of the bracket 12 in the vicinity of the through hole 26 can be ensured while suppressing an increase in the thickness of the bracket 12.

  (4) The support portion 41 is made of the same material as the hollow insulator 32 and is integrally formed with the hollow insulator 32. Therefore, since the number of parts is reduced, the manufacturing cost is reduced and the parts management is facilitated. Further, the support portion can be formed at the same time when the hollow insulator 32 is formed, and the productivity can be improved by forming the hollow insulator 32 and the support portion 41 at the same time.

  (5) A second insertion portion 42 c that is narrower (thinner) than the width of the through hole 26 is formed at the tip of the support portion 41. When the foreign object detection sensor 31 is fixed to the bracket 12, the support portion 41 can be easily inserted into the through hole 26 by inserting the support portion 41 into the through hole 26 from the second insertion portion 42c. Therefore, the foreign object detection sensor 31 can be easily fixed to the bracket 12. In the present embodiment, when the foreign object detection sensor 31 is fixed to the bracket 12, after the second insertion portion 42 c is inserted into the through hole 26, the second insertion portion 42 c is pulled from the opening 23 a of the holding recess 23. Thus, the through hole 26 can be passed through the support portion 41. In this way, the foreign object detection sensor 31 can be fixed to the bracket 12 without applying a large pressing force to the foreign object detection sensor 31.

  (6) While the first insertion portion 42b and the pressing portion 43 can simultaneously penetrate the through hole 26, the second insertion portion 42c and the pressing portion 43 cannot simultaneously penetrate the through hole 26. Therefore, when fixing the foreign matter detection sensor 31 to the bracket 12, the first insertion portion 42 b and the pressing portion 43 are both inserted into the through hole 26, thereby allowing the through hole 26 to penetrate the support portion 41. it can. On the other hand, when an external force in a direction away from the bracket 12 is applied to the foreign matter detection sensor 31 fixed to the bracket 12, the pressing portion 43 is folded toward the second insertion portion 42c and the second insertion portion 42c. Due to the action of the pressing portion 43, the support portion 41 is prevented from coming out of the through hole 26, and the drop of the foreign object detection sensor 31 from the bracket 12 is suppressed.

  (7) Since the foreign object detection sensor 31 is stably fixed to the bracket 12 that is reduced in weight by being formed of resin, the foreign object detection sensor 31 that receives external force from the foreign object X is easily elastically deformed. Accordingly, it is possible to suppress a decrease in detection sensitivity of the foreign matter X.

(8) The foreign object detection sensor 31 is stably fixed to the peripheral edge of the door panel 5 that opens and closes the rear opening 4 provided at the rear of the vehicle 1 and that faces the peripheral edge of the rear opening 4.
(9) The support portion 41 is continuously formed along the longitudinal direction of the foreign matter detection sensor 31 from one end portion to the other end portion in the longitudinal direction of the foreign matter detection sensor 31 (longitudinal direction of the hollow insulator 32). Accordingly, the bracket 12 can be clamped from both sides of the through-hole 26 by the support part 41 and the foreign matter detection sensor 31 at any part in the longitudinal direction of the long foreign matter detection sensor 31. Can be more stably fixed to the bracket 12. Further, the support portion 41 can be easily formed by extrusion.

(11) In the support part 41 penetrating through the through hole 26, the fitting part 42a is fitted into the through hole 26, so that rattling of the foreign object detection sensor 31 is suppressed.
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. However, in addition to the electric back door device 2, the foreign object detection device 11 may be provided in an electric door opening and closing device that electrically opens and closes an opening and closing body that opens and closes an opening provided in the vehicle 1. For example, the foreign object detection device 11 may be provided in an electric slide door device that electrically slides and moves a door panel (opening / closing body) that opens and closes an opening (alight entrance) provided on the side of the vehicle 1. The foreign object detection device 11 may be provided in a sunroof device that electrically opens and closes a roof panel (opening / closing body) that opens and closes an opening provided on the upper surface of the vehicle 1. In any case, the resin bracket 12 is fixed to the peripheral edge of the opening provided in the vehicle 1 or to the peripheral edge of the opening / closing body that opens and closes the opening. Is done. Even in this case, the foreign object detection sensor 31 is stabilized at the peripheral edge of the opening provided in the vehicle 1 or the peripheral edge of the opening / closing body that faces the peripheral edge of the opening while reducing the weight of the vehicle 1. Fixed.

  In the above embodiment, the bracket 12 is fixed to the peripheral edge of the door panel 5 that faces the peripheral edge of the rear opening 4. However, the bracket 12 may be fixed to a portion of the peripheral edge of the rear opening 4 that faces the peripheral edge of the door panel 5.

  In the above embodiment, the energization detection unit 14 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 contact between the electrode wires 33 to 36. However, the energization detection unit 14 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.

FIG. The support portion 61 is formed integrally with the hollow insulator 32, is continuously formed along the longitudinal direction of the foreign object detection sensor 31, and has a constant cross-sectional shape perpendicular to the longitudinal direction. And inside this support part 61, the hollow part 62 which makes this support part 61 hollow is formed. The hollow portion 62 is formed over almost the entire region in the protruding direction of the support portion 61 from the front end of the support portion 61 to the front end of the support portion 61. Moreover, the support part 61 is provided with a pair of press part 63 which protruded in the both sides of the width direction. As shown in FIG. 10, the pressing portion 63 comes into contact with the pressing surface 25 when the support portion 61 passes through the through hole 26, and the bracket 12 is moved from both sides in the through direction of the through hole 26 together with the foreign matter detection sensor 31. Hold it. In this way, as shown in FIG. 9B, the support portion 61 can be easily elastically deformed so as to narrow the width of the hollow portion 62 when passing through the through hole 26. That is, since the hollow portion 62 is formed inside the support portion 61, the support portion 61 is easily deformed, and thus easily penetrates the through hole 26. Therefore, the foreign object detection sensor 31 can be more easily fixed to the bracket 12. Moreover, the weight reduction of the support part 61 can be achieved. Furthermore, the support part 61 in which the hollow part 62 is formed is easily curved in the longitudinal direction. Therefore, even if the shape of the peripheral edge of the door panel 5 is a non-linear shape, the foreign object detection sensor 31 can be easily fixed along the peripheral edge of the door panel 5.

  Moreover, as shown in FIG. 11, you may form the hollow part 71 which makes this insertion part 42 hollow inside the insertion part 42 of the support part 41 of the said embodiment. Even if it does in this way, the effect similar to the example shown to Fig.9 (a) can be acquired.

  Moreover, the structure provided with the hollow part 83 extended to the inside of the press part 82 protruded on the both sides of the width direction like the support part 81 shown to Fig.12 (a) may be sufficient. Even if it does in this way, the effect similar to the example shown to Fig.9 (a) can be acquired. As shown in FIG. 12B, an introduction portion 84 that is narrower than the width of the through hole 26 may be formed at the distal end portion of the support portion 81. If it does in this way, the same effect as (5) of the above-mentioned embodiment can be acquired.

  Further, like the support portion 91 shown in FIG. 13, the hollow portion 92 may be formed only at the base end side portion of the support portion 91. The support portion 91 includes a pair of pressing portions 93 that protrude from both sides of the support portion 91 in the width direction and press the pressing surface 25. The hollow portion 92 is formed in the support portion 91 from the vicinity of the distal end portion (the portion in contact with the pressing surface 25) of the pressing portion 93 to the vicinity of the proximal end portion of the supporting portion 91. Even if it does in this way, the effect similar to the example shown to Fig.9 (a) can be acquired.

  Moreover, the structure provided with the hollow part 102 opened to the front end side of the support part 101 like the support part 101 shown in FIG. Even if it does in this way, the effect similar to the example shown to Fig.9 (a) can be acquired.

  The hollow portions 62, 71, 83, 92, 102 described above are not limited to those formed continuously along the longitudinal direction of the foreign object detection sensor 31, and are not limited to the support portions 61, 41, 81, 91, 101. It may be provided partially.

  In the above-described embodiment, the pair of pressing portions 43 extend from the boundary portion between the first insertion portion 42b and the second insertion portion 42c on both side surfaces in the width direction of the insertion portion 42 toward the foreign matter detection sensor 31, respectively. . However, the pair of pressing portions 43 may be formed so as to extend toward the foreign object detection sensor 31 from both side surfaces in the width direction of the first insertion portion 42b. Further, the support part 41 does not necessarily include two pressing parts 43. Moreover, in the said embodiment, although the 2nd penetration part 42c and the press part 43 cannot penetrate the through-hole 26 simultaneously, the 2nd penetration part 42c is formed so that the penetration hole 26 can be penetrated simultaneously with the press part 43. May be.

-The support part 41 of the said embodiment does not necessarily need to be provided with the 2nd insertion part 42c (introduction part).
In the above embodiment, the support portion 41 is formed from the same material as the hollow insulator 32. However, as shown in FIG. 15, the support 111 formed of a material harder than the hollow insulator 32 (for example, a resin material harder than the hollow insulator 32, an elastically deformable metal material, etc.) is hollow. It may be fixed to the insulator 32. If it does in this way, wobbling of foreign object detection sensor 31 to bracket 12 can be controlled. The phrase “fixed to the hollow insulator 32” includes those in which the support portion 111 and the hollow insulator 32 are formed by integral molding.

  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.

The electrode wires 33 to 36 may be single wires made of annealed copper.
In the above embodiment, the foreign object detection sensor 31 includes a cylindrical outer peripheral surface by including the cylindrical hollow insulator 32. However, the shape of the outer peripheral surface of the foreign object detection sensor is not limited to a cylindrical shape, and may be a polygonal shape, an elliptical cylindrical shape, or the like. In this case, the shapes of the receiving surfaces 27 a and 27 b that are in contact with the outer peripheral surface of the foreign object detection sensor 31 are desirably shapes corresponding to the outer peripheral surface of the foreign object detection sensor 31.

  If the bracket 12 can be clamped from both sides in the penetration direction of the through hole 26 by the foreign object detection sensor 31 and the support part 41 penetrating the through hole 26, the shapes of the foreign object detection sensor 31, the support part 41, and the bracket 12 are The shape is not limited to the above embodiment. For example, the bracket 12 may be configured without the receiving surfaces 27a and 27b.
