To provide a forward/backward moving device which is made compact in size in a forward/backward movement direction.SOLUTION: A forward/backward moving device comprises: a housing 10; a forward/backward moving member 20 which can move forward/backward to and from the housing 10; a forward/backward movement position control mechanism 30 which controls forward/backward movement of the forward/backward moving member 20 between a first position Pa1 on a forward movement side and a second position Pa2 on a backward movement position; a slider 40 which can move in the forward/backward movement direction of the forward/backward moving member 20 together with the forward/backward moving member 20; and a restriction mechanism 50 which can restrict the forward/backward movement of the forward/backward moving member 20. The slider 40 has a slider-side engagement part 42 engaging a radially outer side of the forward/backward moving member 20, and the restriction mechanism 50 has an engagement member 51 engaging the slider 40, and a drive part 52 allowing a movement between an engagement position Pb1 where the engagement member 51 engages the slider 40 and a separation position Pb2 where the engagement member separates from the slider 40.SELECTED DRAWING: Figure 1
【課題】進退方向のサイズの小型化が図られた進退移動装置を提供する。【解決手段】ハウジング10と、ハウジング10に対して進退移動可能な進退部材20と、前進側の第一位置Pa1と後退側の第二位置Pa2と間での進退部材20の進退移動を制御する進退位置制御機構30と、進退部材20とともに進退部材20の進退方向に移動可能なスライダ40と、進退部材20の進退移動を規制可能な規制機構50とを備え、スライダ40は、進退部材20の径方向外側と係合するスライダ側係合部42を有し、規制機構50は、スライダ40と係合する係合部材51と、係合部材51がスライダ40に係合する係合位置Pb1とスライダ40から離間した離間位置Pb2との間を移動させる駆動部52と、を有する。【選択図】図1
