ROTATION STOPPING-HOLDING SWITCHING DEVICE
PROBLEM TO BE SOLVED: To provide a rotation stopping-holding switching device capable of holding a sure stop of a member, and capable of switching a rotation state and a stop-holding state so as to be rotatable without resistance in rotation.SOLUTION: A rotation stopping-holding switching device 100 comprises a body 1 having a shaft part 1a, a pair of pivotal members 4 and 5 arranged so as to surround the shaft part 1a, a rod member 10 for pivotably journaling the pair of pivotal members 4 and 5, a rotary body 3, energization means 8 arranged between spring seats 4b and 5b provided in an end part of the pair of pivotal members 4 and 5, energizing so that the pair of pivotal members 4 and 5 mutually approach and allowing the pair of pivotal members 4 and 5 to abut on the shaft part 1a thereby and switching means 6 for switching abutment and separation between the pair of pivotal members 4 and 5 and the shaft part 1a, and the pair of pivotal members 4 and 5 are pivotally moved and separated from the shaft part 1a by the switching means 6, so that the rotary body 3 can be smoothly rotated.
【課題】部材の確実な停止を保持することができ、回転時には抵抗無く回転可能であるように、回転状態と停止保持状態を切り換えることができる回転停止保持切換装置を提供する。【解決手段】回転停止保持切換装置１００は、軸部１ａを有する本体１と、軸部１ａを囲繞するように配設される一対の枢動部材４、５と、一対の枢動部材４、５を枢動可能に軸支する棒部材１０と、回転体３と、一対の枢動部材４、５の端部に設けられたバネ座４ｂ、５ｂ間に配設され、一対の枢動部材４、５が互いに近接するように付勢し、それにより、一対の枢動部材４、５を軸部１ａに当接させる付勢手段８と、一対の枢動部材４、５と軸部１ａとの間の当接及び離隔を切り換える切換手段６と、を備え、切換手段６により、一対の枢動部材４、５が枢動して軸部１ａから離隔することにより、回転体３をスムーズに回転させることができる。【選択図】図２
