Yes. Therefore, by monitoring the resistance value of the pinch detection sensor 60, it is possible to determine whether the pinch detection sensor 60 is elastically deformed, that is, whether an object is pinched.
The pinch detection sensor 60 is connected to an ECU (control device) by a lead wire (not shown), and its resistance value is constantly monitored by the ECU. When the ECU detects a pinching of an object from a change in the resistance value of the pinching detection sensor 60, the ECU outputs a stop signal to the driving unit 25 of the door moving mechanism 20 and turns on an alarm lamp.

<About opening and closing operation of the glide door 10>
As shown in FIG. 4, when closing the glide door 10 at the entrance / exit opening position, an operation switch (not shown) on the driver's seat is operated in the closing direction. Thereby, first, the drive part 25 of the door moving mechanism 20 operates, and the output shaft 25p rotates right. As a result, the upper and lower main links 21 connected to the output shaft 25p of the drive unit 25 via the connecting link 27 rotate rightward about the support 58 of the entrance 50.

It is drawn into the sideways cutout 34y. The striker 31 is pulled into the lateral cutout 34y of the closed lock mechanism 30 (mechanism main body 32), so that the glide door 10 presses the peripheral edge of the entrance 50, and the weather strip 55 extends over the entire circumference. The entrance / exit 50 is closed in a sealed state by being elastically deformed. Then, when each latch 33 is rotated to the locked position, the glide door 10 is locked at a position where the entrance 50 is closed.
When the glide door 10 is opened from this state, an operation switch (not shown) on the driver's seat is operated in the opening direction. As a result, the closing lock mechanism 30 and the door moving mechanism 20 operate in a procedure reverse to the above-described procedure so that the glide door 10 moves from the position of the entrance 50 to the entrance opening position (see FIG. 4). Become.
Further, in the process of closing the glide door 10, when an object is sandwiched between the glide door 10 and the front column 51 of the entrance 50, the object is hit by the pin detection sensor 60 and the pin detection sensor 60 is elastically deformed. . Thereby, the change in the resistance value of the pinch detection sensor 60 is detected by the ECU, and the ECU operates to stop the drive unit 25 of the door moving mechanism 20. Further, the ECU turns on the alarm lamp.

<Advantages of the closing structure of the glide door 10 according to the present embodiment>
According to the closing structure of the glide door 10 according to the present embodiment, the rotation mechanism 36 of the closing lock mechanism 30 rotates the latch 33 (engagement portion) from the unlocked position to the locked position, and the latch 33 is moved to the striker 31. By the operation of engaging with the (engaged portion), the glide door 10 is pressed against the periphery of the entrance / exit 50 to elastically deform the weather strip 55, and the entrance / exit 50 is closed in a sealed state.
For this reason, unlike the prior art, it is not necessary to move the glide door 10 in the closing direction with the acceleration required for closing the entrance 50 by the door moving mechanism 20. That is, the door moving mechanism 20 only needs to have a minimum force necessary to move the glide door 10 between the position of the entrance / exit 50 and the entrance / exit opening position. For this reason, the output of the door moving mechanism 20 can be reduced as compared with the prior art. Furthermore, since the moving speed of the glide door 10 can be reduced, the glide door 10 can be quickly stopped or reversed when it is detected that an object or the like has been caught.
Further, since a pinch detection sensor 60 is provided at the front edge of the glide door 10, it is possible to grasp at the driver's seat or the like that an object has been pinched when the entrance 50 is closed by the glide door 10. .

<Example of change>
Here, the present invention is not limited to the above-described embodiment, and can be modified without departing from the gist of the present invention. For example, in the present embodiment, the drive unit 25 of the door moving mechanism 20 is configured by a speed reducer including a motor and a gear mechanism. However, the drive unit 25 can also be configured by an air cylinder or the like. . Moreover, although the example using the main link 21 and the auxiliary link 23 for the door moving mechanism 20 has been shown, it is also possible to use a rail or the like for guiding the glide door 10 instead of the main link 21 and the auxiliary link 23.
Moreover, although the example which uses the sensor which changes resistance value by elastically deforming as the pinching detection sensor 60 was used, instead of this, for example, a sensor whose internal pressure changes by elastically deforming is used. It is also possible to adopt a configuration in which pinching is detected by detecting this.
