ROTARY TELESCOPIC DEVICE
To provide a rotary telescopic device that can suppress twisting of a coil spring when a rod is pushed in and rotated, thereby preventing the malfunctioning of the rod.SOLUTION: This rotary telescopic device 10 has a body member 11, a rod 40, a spring housing space 44 provided in the rod, a coil spring 50 that urges the rod 40, a cam mechanism formed between the rod 40 and a tubular part 15 that causes the rod 40 to move axially and concurrently to rotate, and a spacer 80 positioned between one end of the coil spring 50 and a closed end portion 43. A rotating sliding portion is provided between the spacer 80 and the closed end portion 43, locally contacting the spacer 80 and the closed end portion 43, including a portion located at the axial center C of the coil spring 50.SELECTED DRAWING: Figure 4
【課題】ロッドを押し込んで回転させる際のコイルバネのねじれを抑制して、ロッドの作動不良を抑制できる回転式伸縮装置を提供する。【解決手段】この回転式伸縮装置１０は、本体部材１１と、ロッド４０と、ロッド内に設けられたバネ収容空間４４と、ロッド４０を付勢するコイルバネ５０と、ロッド４０及び筒状部１５間に形成され、ロッド４０を回転させつつ軸方向移動させるカム機構と、コイルバネ５０の一端部と閉塞端部４３との間に配置された、スペーサ８０とを有しており、スペーサ８０と閉塞端部４３との間に、コイルバネ５０の軸心Ｃに位置する部分を含むように、スペーサ８０と閉塞端部４３とを局所的に当接させる、回転摺動部が設けられている。【選択図】図４
