A fully closed position in which the doorway provided on the side surface of the vehicle body 2 is closed by a manual operation and an electric opening / closing drive device PSD mounted in the rear part of the vehicle body 2 and supported by the doors 2B and 2C. From the outer side of the vehicle body 2 to the fully open position moved backward along the side surface of the vehicle body 2 and vice versa. The drive unit 3 other than that shown in FIG. 1 is for the left door and is disposed in the left side panel of the vehicle body 2.

  The door opening / closing drive device PSD includes a drive unit 3 attached to the vehicle body 2, and an opening cable 10 and a closing cable 11 formed by a Bowden cable or the like for transmitting power output from the drive unit 3 to the door 1. Including.

  As shown in FIGS. 2 and 3, the drive unit 3 includes a synthetic resin first housing 5 fixed to the vehicle body 2 and a synthetic resin second housing 6 formed separately from the first housing 5. The housing 4, a motor 7 capable of rotating in the forward and reverse directions, and a worm wheel 9 that is rotatably supported by a pivot 8 that faces the inside and outside of the vehicle 4 to reduce the rotation of the motor 7 to form a rotatable reduction gear. And a rotary drum 12 that is pivotally supported by a pivot 8 and is wound and connected with an opening cable 10 and a closing cable 11, and a power transmission path between the worm wheel 9 and the rotary drum 12 can be interrupted.
