Next, when the door 14 is opened, the locking claw 52 of the locking device 51 is removed, and a door opening / closing switch (not shown) is opened to rotate the electric motor 20 in the other direction. It rotates in the direction opposite to the arrow. By this rotation, an operation opposite to the closing operation is performed, the pedestal 8 moves forward, the door 14 moves along a locus opposite to the closing locus, and the linear guide 9 extends, as shown in FIG. In addition, the door 14 is opened in a state of slightly protruding from the outer surface 1a of the vehicle outer plate.
[0040]
In this opening operation, the coil spring 41 of the power assist mechanism 38 tilts forward beyond the dead point, and the support arm 7 swings to assist the force that must lift the load of the door 14 and the like.
[0041]
When the door 14 is opened, this is appropriately detected by a sensor or the like, and the electric motor 20 stops.
When the electric motor 20 stops with the door 14 closed and opened, the brake unit 21 applies the brake.
[0042]
However, when the door 14 is manually opened and closed in the event of an emergency involving a power failure, it is difficult to manually open and close the door if the brake is applied. Therefore, at the time of manual opening and closing, the manual release mechanism 45 is disengaged to disengage the clutch 23, and the association with the brake unit 21 is released to facilitate the manual opening and closing of the door 14.
