As is clear from the above, in the present invention, since the automatic door opening/closing device and the window regulator device in the door can be efficiently and selectively driven with a single motor, each device can be driven separately. Since there is no need to provide a dedicated motor, the space occupied inside the door is reduced accordingly, making it possible to secure sufficient space inside the door for storing other devices, and reducing the weight of the door. Moreover, it is possible to equalize the power supply to each device, and it is possible to design a balanced design as a whole, which is of great significance.

In addition, in the above-mentioned embodiment, the first output shaft 6
is connected to the rotating shaft 4a of the motor 4 without using a clutch, and is connected to the electromagnetic clutch 24 provided in the reducer 19.
The transmission of the driving force of the first output shaft 6 to the automatic door opening/closing device A is made intermittently.
The speed reducer 19 may not be provided with a clutch, but a clutch similar to the electromagnetic clutch 12 provided on the second output shaft 7 may be provided between the first output shaft 6 and the second gear 11. In this way, the power supply to both devices can be switched simply by operating the clutch in the transmission 5, making handling convenient.
