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
【課題】駆動部による動力と、外力との、2種類の手段で従動部材を動かすことができ、さらに、従動部材の停止時に複雑な制御なく適宜なロックを掛けることができる駆動装置、および、バックドア開閉装置を提供すること。【解決手段】従動部材と、駆動軸と従動部材との間の動力伝達経路における遊星ギヤ機構20と、駆動部の動力を遊星ギヤ機構から従動部材に伝達する伝達部材30、40と、駆動部の動力により回転する回転体10と、コイルバネ9と、第1規制部材4と、第2規制部材5と、第3規制部材6と、コイルバネ9の第1端部9aを周方向へ移動させることが可能、且つ、第2端部9bを周方向へ移動させることが可能な可動部材7とを有し、伝達部材30、40または駆動軸2aの回転により、可動部材7が第1端部9aまたは第2端部9bを移動させてコイルバネ9による回転体10の締付解除を行う。【選択図】図1
