Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a door driving device for a vehicle capable of reducing the number of components and simplifying a structure.SOLUTION: The door driving device for a vehicle includes a planetary gear mechanism G1 comprising a sun gear 38d, a ring gear 39b surrounding the sun gear 38d, a planetary gear 41 engaged with the sun gear 38d and the ring gear 39b and a carrier revolving with the planetary gear 41. By turning the sun gear 38d to a drive shaft to be rotationally driven by a motor 22, turning the carrier to a driven shaft and turning the ring gear 39b to a fixed shaft, the driving device decelerates the rotation of the motor 22, transmits it to a drum 23 as an output member to rotate it, and opens/closes a vehicle door. In such a door driving device for a vehicle, by attaching a planetary shaft 42 to a bottom wall part 23a of the drum 23 and supporting the planetary gear 41 on the shaft 42, the bottom wall part 23a is made to function as the carrier.
