PROBLEM TO BE SOLVED: To provide a handle operation device that makes it possible to easily detach a handle from a rotary shaft while making it possible to eliminate a trouble such as a third person having no key operating an apparatus illegally by enabling only a manager having a key for a locking mechanism to operate the apparatus.SOLUTION: A handle 1 include a central fitting part in a cylindrical shape, the central fitting part being loosely fitted to a central shaft member 2 in a column shape, the central shaft member being fitted to a shaft end 31 of a rotary shaft 3. A fitting member 6 to be operated by a locking mechanism 4 provided in the handle 1 is made to be in a state where the fitting member is fitted into a fitting recess 21 formed on the central shaft member 2. Thereby, a coupled state where the handle 1 is locked with the rotary shaft 3 via the fitting member 6 and central shaft member 2 and a non-coupled state where releasing the fitting state makes the handle 1 be free from the rotary shaft 3 can be selected. The handle 1 can be made to be detached from the rotary shaft 3 by releasing the state where the central shaft member 2 is fitted to the shaft end 31 of the rotary shaft 3.SELECTED DRAWING: Figure 1
【課題】施錠機構のキーを有する管理者だけが機器を操作することができ、キーを有しない第三者が不正に機器を操作するといったトラブルを解消できるようにしながら、ハンドルを回転軸から容易に取り外すことができるようにしたハンドル操作装置を提供すること。【解決手段】回転軸３の軸端部３１に嵌合する円柱形状の中心軸部材２に、ハンドル１の円筒形状の中心嵌合部を遊嵌し、中心軸部材２に形成した嵌合凹部２１に、ハンドル１に配設した施錠機構４によって操作される嵌合部材６を嵌合状態にすることによってハンドル１が嵌合部材６及び中心軸部材２を介して回転軸３とロックされる連結状態と、嵌合状態を解除することによってハンドル１が回転軸３とフリーになる非連結状態とに選択可能とし、回転軸３の軸端部３１に対する中心軸部材２の嵌合状態を解除することによってハンドル１を回転軸３から取り外すことができるようにする。【選択図】図１
