Abstract
【解決手段】伸縮装置12は、第1管状体16と、第1管状体16内に移動可能に挿入した第2管状体17と、第2管状体17内に移動可能に挿入した第3管状体18とを備える。伸縮装置12は、第3管状体18の第2管状体17に対する移動を規制する規制手段22を備える。規制手段22は、突出方向への移動により内孔部26から第3管状体18外に突出して外孔部24に入り込む規制体31と、規制体31を突出方向に向けて付勢する付勢体とを有する。伸縮装置12の縮み動作途中で、突出状態の規制体31が第1管状体16の軸方向端部16aに当接すると、その規制体31が、軸方向端部16aによる押圧にて反突出方向に移動した後、第2管状体17の外孔部24の周縁による押圧に基づく反突出方向への更なる移動により外孔部24から脱出する。
