To prevent a light receiving portion of a camera or the like from being contaminated.SOLUTION: A cylindrical gear 1 of a drive device has projections 1a on an outer periphery of its cylindrical portion that are arranged in a direction along a first axis C, and in a circumferential direction. The cylindrical gear 1 has a first moving body 2 on one end in the direction of the axis (along the first axis C). A second moving body 3 is arranged outside on the one end where the first moving body 2 is arranged. A conversion mechanism 4 converts the movement of the cylindrical gear 1 in the direction along the first axis C between the first moving body 2 and the second moving body 3, into the movement of the second moving body 3.SELECTED DRAWING: Figure 1

    【課題】本発明は、カメラ等の受光部の汚れを防止することを目的とする。【解決手段】駆動装置の円筒ギア1は、その円筒面の外周に第1の軸線に沿う方向C、および、円周方向の各々に凸部1aを有する。この円筒ギア1は、軸線(第1の軸線に沿う)Cの方向の一端側に第1の移動体2を有する。前記第1の移動体2から前記一端側より外方となる位置には、第2の移動体3が配置されている。変換機構4は、これら第1の移動体2と第2の移動体3との間で前記円筒ギア1の第1の軸線方向Cへの移動を前記第2の移動体3の移動に変換する。【選択図】図1
