, And the door panel 18 is slid toward the front side of the vehicle 14 via the endless belt 36 and the center arm 50.

If foreign matter is present on the slide track of the door panel 18 when the door panel 18 slides forward to fully close the entrance 58, the end (front end) of the door panel 18 in the closing movement direction contacts the foreign matter. To press foreign matter. When the protector 144 and the outer cover 124 are elastically deformed by the pressing reaction force from the foreign matter at this time, the electrode wire 12 in the outer cover 124
8 or the electrode line 132 comes into contact with the electrode line 130 or the electrode line 134 to conduct and short-circuit. As described above, at this time, the current flowing through the electric circuit including the electrode lines 128 to 134 (see FIG. 11) flows without passing through the resistor 136. Therefore, for example, if the current is passed through this circuit at a constant voltage, The value changes, and the outer skin portion 124 detects the change in the current value at this time. When the outer cover 124 detects a change in the current value, the computer 96 operates the slide door driver 94 and the closer driver 110 to reversely drive the slide door motor 28 and the closer motor 104 to move the door panel 18 to the rear side of the vehicle 14. Slide. This can prevent foreign matter from being caught by the door panel 18.

By the way, in the present pressure detecting device 10,
The lead wire 138 is the lead wire accommodating portion 1 of the bracket 160.
64 (housing groove 166), the vehicle 12
The lead wire 138 is hidden (shielded) by the lead wire accommodating portion 164 from the right side of the vehicle. Never touch. The accommodation groove 166 of the lead wire accommodation portion 164 is open to the left of the vehicle 14, but is formed on the left side of the lead wire accommodation portion 164 by a portion near the front end of the inner panel 54 and the outer panel 56. Vehicle 1
The accommodation groove 166 is hidden (shielded) from the left side of FIG. Therefore, when the occupant gets on and off the vehicle from the entrance 58, the body of the occupant is carried by the baggage 1
The lead wire 138 in 66 is not touched, and the lead wire 138 is not broken.

The lead wire 1 of the pressure sensor 120 and the lead wire 1
In the vicinity of the lower end of each of the brackets 38, the cover 1 of the bracket 160
74. Therefore, when an occupant gets on and off from the entrance 58, the lead wires 139 and 140 drawn out from the lower end of the lead wire 138, the electrode wires 128 to 130 drawn out from the lower end of the outer cover 122, and their connection parts The occupant's body and the baggage carried by the occupant do not touch directly.

Further, the cover 174 is opened to the left of the vehicle 14, and the above-mentioned shielding portion 158 is provided on the left side of the cover 174 from the left side of the vehicle 14.
Is shielded. Therefore, when an occupant gets on and off from the entrance 58, the lead wires 139 and 140 drawn out from the lower end of the lead wire 138, the electrode wires 128 to 130 drawn out from the lower end of the outer cover 122, and their connection parts The occupant's body and the baggage carried by the occupant do not touch directly. Therefore, there is no possibility that the electrode wires 128 to 134, the lead wire 138, and their connection portions are disconnected. Moreover, the electrode wire 130 and the electrode wire 13
2 and the connection portions between the electrode wires 128 and 134 and the respective lead wires 139 and 140 of the lead wire 138 are fixed to the bottom of the cover 174 while being insulated from the cover 174 by an adhesive. Since the door panel 18 is supported by the 174, the electrode wires 128 to 128 are generated by inertia force when the door panel 18 slides back and forth, vibration of the running vehicle 18 and the like.
There is no possibility that the wires 134, the lead wires 138, and their connection portions are disconnected.

The pressure sensor 120 is connected to the door panel 18.
When assembling, the mounting groove 1
52, the support portion 168 of the bracket 160 is fitted,
The pressure-sensitive sensor 120 and the bracket 160 are assembled in an assembled state.
Is accommodated in the accommodation groove 166, and the conductors 139 and 140 and the outer sheath 12 drawn out from the lower end of the lead wire 138 are accommodated.
By fixing the respective connection portions of the electrode wires 128 to 130 drawn out from the lower end of the cover 2 to the bottom of the cover 174 with an adhesive, the assembling to the door panel 18 is basically performed by attaching the base 162 to the door panel 18. It is only necessary to fix the lead wires 138 and the electrode wires 12 at the time of assembly.
The application of external force to the doors 8 to 134 can be extremely reduced (that is, the lead wires 138 and the electrode wires 128 to 134 are extremely rarely pulled in order to mount the pressure-sensitive sensor 120 to the door panel 18). For this reason,
Disconnection during assembly work can be prevented.

In the present embodiment, the bracket 160 has the lead wire accommodating portion 164 for accommodating the lead wire (connection means) 138 as a support means. However, when the bracket 160 is considered as a shielding means. In other words, the bracket 160 only needs to shield the lead 138 from the vehicle interior side on the side of the lead 138. Therefore, in this case, the lead wire accommodating portion 164 may not be formed on the bracket 160.

In the present embodiment, a part of the door panel 18 is used as the shielding part 158 and the shielding part 158 is used as the shielding means. However, the configuration of the shielding means is not limited to this. Housing groove 166 of portion 164
May be provided with a long plate-like lid, and this lid may be used as a shielding means.

Next, a second embodiment of the present invention will be described. In the following description of the second embodiment, parts that are basically the same as those in the first embodiment are given the same reference numerals, and descriptions thereof are omitted.

FIG. 13 is a sectional view showing the configuration of a main part of a pressure detecting device 200 according to a second embodiment of the present invention.

As can be seen from a comparison between FIG. 2 and FIG. 13, the outer shape of the lead wire 138 is substantially rectangular in the first embodiment, whereas in the present embodiment, the lead The cross-sectional shape of the outer skin of the line 138 is a trapezoidal shape in which the thickness dimension (that is, the dimension in the direction along the front-rear direction of the vehicle 14) gradually decreases outward in the vehicle width direction.

In the present embodiment, the accommodation groove 204 is formed in the lead wire accommodation section 164. Accommodation groove 204
Is the same as the housing groove 166 in the first embodiment in that the lead wire 138 is housed inside the housing groove 166. However, the housing groove 166 has the same width dimension of the inner bottom and the opening width of the opening end. On the other hand, in the present embodiment, the width of the accommodation groove 204 gradually decreases from the inner bottom to the opening side. The width of the opening at the open end of the housing groove 204 is substantially equal to the width of the outer end of the outer surface of the lead wire 138 on the vehicle left side (that is, when the outer electrode has a trapezoidal cross section, it corresponds to the upper bottom). It is narrower than the width of the right end (that is, when the outer shell has a trapezoidal cross-sectional shape, it corresponds to the lower base).

For this reason, in the present embodiment, the accommodation groove 20
4 accommodates the lead wire 138, the accommodation groove 204
Of the vehicle restricts the movement of the lead wire 138 to the left side of the vehicle. Therefore, in the present embodiment, the lead wire 138
From the inside of the accommodation groove 204 can be prevented.

This embodiment is the same as the first embodiment except that the shape of the housing groove 204 is different from the shape of the housing groove 166 in the first embodiment. Therefore, the same operation as the first embodiment can be achieved, and the same effect can be obtained.

In the present embodiment, the outer shape of the outer surface of the lead wire 138 is formed in a trapezoidal shape in which the upper base is shorter than the lower base, and the width dimension of the accommodation groove 204 is gradually narrowed toward the opening end. For example, as shown in FIG. 14, the outer shape of the lead wire 138 is circular in cross section, and the inner peripheral portion of the accommodation groove 204 is a circle substantially equal to the curvature of the outer peripheral portion of the lead wire 138, as shown in FIG. The configuration may be an arc shape, and the angle of the arc from one end to the other end in the circumferential direction of the lead wire 138 may be larger than 180 degrees. In such a configuration, the opening angle of the opening end around the center of the inner peripheral portion of the accommodation groove 204 is
Since the angle is smaller than 180 degrees, the opening width at the opening end is smaller than the diameter of the lead wire 138. Therefore, even in the modified example shown in FIG. 14, the lead wire 138 can be prevented from coming out of the accommodation groove 204.

Further, in each of the above embodiments, the lead wire 138 is used in which the conductors 139 and 140 are embedded in the outer skin and integrated, but the configuration of the connection means is not limited to this. Absent. For example, wires 139, 140
The conductor 139 and the conductor 140 may be separated from each other without being integrated with an outer sheath or the like, and may be used as connecting means with these. The connection means may have a configuration in which the conducting wires 139 and 140 are inserted inside a sufficiently large hose or the like.

In each of the above embodiments, the inner shape of the housing grooves 166 and 204 of the lead wire housing 164 as the housing corresponds to the outer shape (of the outer skin) of the lead 138. 138 was fitted into the accommodation grooves 166 and 204. That is, in each of the above-described embodiments, the accommodation grooves 166 and 204 hold or can hold the lead wire 138, though the degree is different. However, the housing section may have any configuration as long as it can guide the connecting means, and the housing section does not need to be configured to perform the connecting means. That is, the lead wire 138 (the conductive wires 139 and 14
Conductors 139, 140 when 0 is not covered with outer skin)
May simply be laid in the accommodation groove 166 or the accommodation groove 204 (that is, the accommodation part simply accommodates the connection means).
