ROTARY RECIPROCATING OPERATION DEVICE, STOPPER OPERATION DEVICE, STOPPER, AND DOOR WITH STOPPER
To provide a rotary reciprocating operation device, a stopper operation device, a stopper, and a door with a stopper capable of temporarily fixing an object to be moved at a desired position.SOLUTION: A rotary reciprocating operation device 30 includes an abutment shaft 19 housed in a cylinder 38 and capable of protruding from the open end of the cylinder 38, an elastic portion 41 that is housed in the cylinder and applies an elastic force to the abutment shaft in a direction protruding from the cylinder, an operating portion 12 that slides the abutment shaft in the cylinder against the elastic force, two rows of guide teeth formed on the cylinder and having convex portions 46 and 47 arranged along the circumferential direction of the cylinder, a peripheral tooth 44 protruding from the body of the abutment shaft between the two rows of guide teeth, slopes 46a, 47a formed on the convex portion and receiving a force from the elastic portion 41 or the operating portion to change the sliding direction of the peripheral teeth that try to slide along the longitudinal direction of the cylinder, and a stopper groove 49 that is provided in the guide tooth on the open end side and is long in the longitudinal direction into which the peripheral tooth 44 is fitted.SELECTED DRAWING: Figure 4
【課題】動こうとする物を所望の位置で一時固定することができる回転往復作動装置、ストッパ操作装置、ストッパ、及びストッパ付扉を提供する。【解決手段】回転往復作動装置３０は、シリンダ３８に収容されてシリンダ３８の開口端から突出可能な突当シャフト１９と、シリンダに収納されて突当シャフトにシリンダから突出する向きに弾性力を付与する弾性部４１と、突当シャフトを弾性力に反してシリンダ内をスライドさせる操作部１２と、シリンダに形成されてシリンダの周方向に沿って凸部４６，４７が並ぶ２列のガイド歯と、２列のガイド歯の間で突当シャフトの胴部から突起する周回歯４４と、凸部に形成されて弾性部４１又は操作部による力を受けてシリンダの長手方向に沿ってスライドしようとする周回歯のスライド方向を変更する斜面４６ａ，４７ａと、開口端側のガイド歯に設けられて周回歯４４を嵌まり込ませる長手方向に長いストッパ溝４９と、を備える。【選択図】図４
