なっている。2. Description of the Related Art A conventional example of this type of apparatus is disclosed in Japanese Patent Publication No. Sho 62-22008. This device connects a vehicle body and a door with a pushing rod whose one end is pivotally attached to the vehicle body, and the other end of the pushing rod is pivotally attached to the inside of the door with a substrate and swings back and forth by a motor. A speed reducer that is connected to the free end of the sector gear and that further reduces the rotation of the motor between the sector gear and the motor and transmits the rotation of the motor to the sector gear. In order to prevent the movement of the reverse direction from being transmitted to the motor, an electromagnetic clutch that is in the disengaged state is provided between the sector gear and the speed reducer, and the electromagnetic clutch is put in the connected state by opening and closing the operation switch provided on the driver's seat. By transmitting the rotation of the motor to the sector gear and pushing and pulling the pushing rod in the longitudinal direction, the door can be opened and closed.
