When the transmission device is operated to be released from the reverse position and the on signal is within a predetermined time, the output of the signal to the motor drive / stop determination circuit 71 is canceled and the motor 62 is not driven. . Further, when the transmission device is operated so as to be released from the reverse position, the reverse switch 92 is turned off, and the off signal is input to the signal determination circuit 73, the signal determination circuit 73 outputs the signal from the reverse switch 92. When the off signal is input, it is determined whether or not the on signal is input from the vehicle speed switch 95, and the vehicle speed switch 9
5 is not input to the signal determination circuit 73 (the vehicle speed switch 95 outputs the OFF signal to the signal determination circuit 73).

When an ON signal is input from the vehicle speed switch 95 to the motor drive / stop circuit 71 via the input circuit 92, the motor drive / stop determination circuit 71 determines the reverse rotation drive of the motor 62 and outputs the signal to the drive circuit 71. Output. As a result, the motor 62 is driven in the reverse direction, and the movable member 3 moves from the use state B to the non-use state A.

Since the forward / reverse driving of the motor 62 and the stopping of the motor 62 by the manual switch 91 are the same as those in the first embodiment, the description thereof will be omitted.

As described above, the drive of the motor 62 is controlled by the duration of the signal from the reverse switch 92 and the vehicle speed when the signal from the reverse switch 92 is input. The movable member 3 can be kept in the used state B by restricting the movement of the certain movable member 3 to the non-used state A. In addition, the movement of the movable member 3 from the non-use state A to the use state B when the transmission device is momentarily operated to the reverse position can be restricted.

Although the control circuit 7 is housed in the case 8 and fixed to the housing 61, it may be fixed inside the vehicle 1. Further, although the motor drive / stop circuit 71 and the signal determination circuit 73 are separately configured, the signal drive circuit 73 may be incorporated into the motor drive / stop circuit 71 by a microcomputer.
