Abstract:
PROBLEM TO BE SOLVED: To provide a driving gear and a back door opening/closing device capable of moving a follower member by two types of means, namely drive force from a drive part and external force, and also capable of locking the follower member appropriately without complicated control when the follower member comes to a halt.SOLUTION: A driving gear and a back door opening/closing device include: a follower member; a planetary gear mechanism 20 on a drive force transmission path between a drive shaft 2a and the follower member; transmission members 30 and 40 for conveying the drive force of the drive part to the follower member from the planetary gear mechanism; a rotary body 10 rotated by the drive force of the dive part; a coil spring 9; a first regulation member 4; a second regulation member 5; a third regulation member 6; and a movable member 7 capable of moving a first end 9a of the coil spring 9 in a circumferential direction and moving a second end 9b in the circumferential direction. The movable member 7 moves the first end 9a or the second end 9b when the transmission members 30 and 40 or the drive shaft rotates, for fastening release of the rotary body 10 by the coil spring 9.SELECTED DRAWING: Figure 1
