PROBLEM TO BE SOLVED: To minimize an actuating device for a sliding door of a vehicle. SOLUTION: This motor-driven actuating device 10 used for a sliding door of a vehicle is constituted of a sun gear, a few pinion gears 24 rotatably fitted to a planet carrier 26 and arranged to mutually mesh with the sun gear, and a ring gear 28 mutually meshing with the pinion gears 24. The sun gear, the planet carrier 26, and the ring gear 28 are constituted together of a planet gear set 12 rotatable around the shaft A, an electric motor 14 connected to the planet carrier 26 to rotate the planet carrier 26 around the shaft, an electric brake 16 connected to the sun gear to brake the revolution of the sun gear around the shaft, a cable drum 18 rotated by the ring gear 28, and a cable wound up on the cable drum, which is connectable to the sliding door. And hence, the whole dimensions of the acuating device can be reduced. |
