To provide a forward/backward moving device which can move a lock member to a lock position irrespective of the position of a forward/backward member in an axial direction, and can move the forward/backward member to a backward holding position even when the lock member is in the lock position.SOLUTION: A forward/backward moving device 1 comprises a case 2, a forward/backward member 3, an energization member, a cam mechanism C, and a lock member 5. An end part of the forward/backward member 3 on a backward direction D2 side has a protrusion 3a protruding in the backward direction D2 in an axial direction, and a recess 3b which is formed so as to be recessed with respect to the protrusion 3a. The protrusion 3a has an abutment part CT which can abut on an abutted part 5a of the lock member 5 when in the lock position. When the backward member 3 has reached a return position from a forward holding position, the abutment part CT lies at a position which does not face the abutted part 5a in the axial direction. When the backward member 3 is held in a backward holding position, the abutment part CT lies at a position which faces the abutted part 5a in the axial direction.SELECTED DRAWING: Figure 19

    【課題】本発明は、進退部材の軸方向の位置にかかわらず、ロック部材をロック位置に移動させることができ、ロック部材がロック位置に位置している場合でも進退部材を後退保持位置へと移動させることができる進退移動装置の提供を目的とする。【解決手段】進退移動装置1は、ケース2と、進退部材3と、付勢部材と、カム機構Cと、ロック部材5とを備え、進退部材3の後退方向D2側の端部は、軸方向で後退方向D2に突出した凸部3aと、凸部3aに対して凹状に形成された凹部3bとを有し、凸部3aはロック位置にあるロック部材5の被当接部5aと当接可能な当接部CTを有し、進退部材3が前進保持位置から折り返し位置に到達したときには、当接部CTが被当接部5aに対して、軸方向で対向しない位置に位置し、進退部材3が後退保持位置に保持されたときには、当接部CTは被当接部5aに対して、軸方向で対向した位置に位置する。【選択図】図19
