As the switch lever 86 is rotated, the roller support shaft 9 3 and the lock release operation roller 9 4 connected to the support shaft 8 4 via the switch operation disk cam 9 2 also rotate integrally. The roller 9 4 is switched from the previous release position to the lock release position shown by the two-dot chain line in FIG. 11 and FIG. 13. In other words, the above-mentioned lock release operation roller 9 4 presses and operates the operated portion 7 6 b of the bracket 7 6 fixed to the lock switch pin 5 6 from the side plate 5 3 side to force the same pin The pin 5 6 resists the elastic pressure of the compression wire spring 6 2 to retract it to the unlocked position. With this, the restriction of the locking arm 40 is released, and the sliding door 10 is unlocked, so that the passenger can manually open the sliding door 10 to the outside of the vehicle. The consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed the above-mentioned unlocking operation roller 9 4, which is located closer to the rotation center axis, that is, the support shaft 8 4, than the rotating end of the switching handle 86, and the rotation radius is very small. Therefore, for example, by holding the end of the switching handle 86, a large moving force can be applied to the lock release operation roller 94 with a small handle operation force. Therefore, even when the spring pressure of the compression coil spring 62 is large, it is possible to forcefully switch the lock switching pin 5 6 to the unlocked position with sufficient force. On the other hand, at the time point when the above-mentioned lock release operation roller 9 4 is turned to the lock release position, the operation protrusion 9 2 a of the switch operation panel cam 9 2 presses the contact roller 9 6 of the operation release operation detection switch 7 2 This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) " -34- 527463 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5.

When the switch 7 2 is in the ON state, that is, when the switching handle 8 6 is operated to the up position, then Wait until the same handle 86 is returned to the down position (that is, the release operation detection switch 72 is turned off), and then the door driving is started. Thereby, the switch lever 8 6 is switched to the upright position (that is, the lock release operation roller 9 4 is switched to the lock release position), and the normal door driving can be prevented from restarting in advance. In this embodiment, if the sliding door 10 is still open and the switching handle 8 6 is returned to the down position, although the locking switching pin 5 6 will return to the original locked position, the rotating member 3 6 Since it is at an inclined position shown by a two-dot chain line in FIG. 3, the above-mentioned lock switching pin 5 6 cannot be returned to the locked position abutting on the back surface of the rotating member 36. Therefore, although the sliding door 10 is not in the regular fully closed position and becomes locked, the so-called air vibration phenomenon is prevented. Then, if the sliding door 10 is returned to the fully closed position by manual operation or motor drive, the rotating member 36 will return to the solid line position (upright position) in FIG. 3 and the lock switch pin 5 will be locked. 6 protrudes toward the locked position, so the sliding door 1 will automatically lock again. In this embodiment of the device, the cable 1 0 4 can be pulled by operating the operating handle on the outside of the vehicle, and the lock can also be unlocked by the pulling force. 1 0 8 Switch to the unlocked position to forcibly retract the lock switch pin 5 6 to the unlocked position.

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs in the above-mentioned embodiment, the operating piece 7 6 b protruding from the lock switch pin 5 6 in the diameter direction is pushed by the lock release operation roller 9 4 To perform forced lock release, for example, it is also possible to make the protruding portion protrude from the switch lever 86 which is the lock release operation portion, and insert the recess into the groove provided in the lock switch pin 56 to perform the above switching. The handle 8 6 is linked with the lock switching pin 5 6. However, in this case, the driving of the lock switching pin 5 6 usually causes the switch lever 86 to rotate, which may hinder the smooth driving of the lock switching pin 5 6. However, if the above embodiment is adopted, With the pressing operation method, it is possible to prevent the smooth operation of the lock release operation portion from being hindered. In the present invention, the operation detection means is not necessarily required. When a release operation detection means is provided, it is not limited to the structure shown in the figure, for example, an optical switch or an electromagnetic switch may be used. However, by using a switch operating member (switch operation panel cam 9 2) that is turned in one piece with the switching handle 8 6 as shown in the figure, the detection switch is operated, that is, the operation is released. ) A4 specification (210x297 mm) -36- 527463 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5.

In the present invention, the specific shape or structure of the lock switch member is not limited. For example, the lock switch member may be directly engaged with an engagement portion provided on a door of a vehicle to lock the lock switch member. Does not interfere with the construction of the conventional locking device. The rotation position or operation angle of the switching lever 86 can be appropriately set, and the rotation direction is not particularly limited. For example, the switching handle 86 can also be rotated on a horizontal plane. However, if the rotation position of the switching lever 86 is set as shown in the figure, in the normal period, that is, when the lock release operation roller 94 is in the release position, the switching lever 86 is in the down position, so There is no obstruction inside, and when the lock release operation roller 9 4 is switched to the lock release position to forcibly release the lock, the above-mentioned switch lever 8 6 will be in an upright state, so the forced release can be confirmed from the handle position at a glance position. In particular, if the above-mentioned down position is set to the down position, as shown in the figure, the switching lever 86 is installed on the upper side of the door of the vehicle together with the lock device 30 and the opening and closing drive device 20. , Even a shorter person can operate the switching handle 86 without any obstacle, and can provide a more useful structure. The switching lever 86 may be mounted on the vehicle side instead of the frame side. However, by making the switch lever 8 6 rotatably supported on the frame side (support frame 5 4 in the illustration) as in the above embodiment, the switch lever 8 6 and the solenoid coil device 5 8 can be integrated as it is. When assembled into a vehicle, the construction process of the vehicle can be further reduced.
