Provided is a reciprocating motion device wherein: a reciprocating member that can move reciprocally with respect to a case is biased with a biasing member to the advanced position side from the retracted position side; one of the case and the reciprocating member is provided with an engaged section and the other is provided with an engaging section; the engaged section is provided in a spiral shape around the axis of the reciprocating member; the engaging section slides with the engaged section due to the restriction of relative movement in the axial direction of the reciprocating member by being engaged with the engaged section; the reciprocating member is provided so as to move relative to the case in the axial direction of the reciprocating member while rotating relative to the case due to the engaged section sliding with the engaging section; the biasing member biases the reciprocating member in one rotational direction when the reciprocating member advances; and the engaged section has a blocking section to block the reciprocating member from retracting by abutting the engaging section when the reciprocating member is pressed in the retracting direction without the engaging section sliding with the engaged section. With this reciprocating motion device, it is possible to prevent the reciprocating member in the advanced position from moving in the retracting direction even if same receives a unidirectional external force to move in the retracting direction due to malicious operation or the like.
通过使用进退移动装置，即使处于前进位置的进退构件因恶意操作等而受到向后退方向移动的一个方向的外力，也能够防止向后退方向的移动，该进退移动装置对能够相对于壳体进退移动的进退构件利用施力构件从后退位置侧向前进位置侧施力，在壳体和进退构件中的一方设置被卡合部，在另一方设置卡合部，被卡合部在绕进退构件的轴的方向上呈螺旋状设置，卡合部通过与被卡合部的卡合而限制进退构件的轴向的相对移动，从而与被卡合部滑动，进退构件以通过被卡合部与卡合部的滑动而相对于壳体一边相对旋转一边在进退构件的轴向上相对移动的方式设置，施力构件在进退构件前进时对进退构件在一个旋转方向上施力，被卡合部具有在进退构件以不伴随卡合部与被卡合部的滑动的方式被向后退方向按压时与卡合部抵接而阻碍进退构件的后退的阻碍部。
