態で設けであることを特徴とする弁開閉用操作構造。A clutch that interlocks and connects a rotary handle 9 for manual operation and a drive mechanism M to a rotary shaft 8 for valve opening/closing operation so that it can be rotated, and connects and disconnects the handle 9 and the rotary shaft 8. The valve opening/closing operation structure is provided with a mechanism C, and the clutch mechanism C is configured such that the handle 9 is slidable and relatively rotatable on a rotational support shaft 10 that rotates integrally with the rotational shaft 8. The support shaft 10! An elastic plate-like piece 11 that engages and disengages from the occlusal protrusion 12 by moving forward and backward along the axis of the spindle.
The outer periphery of the handle 9 is attached to a cap that can rotate and slide integrally, and the plate-like piece 11 is locked and supported so as to maintain the occlusal state, and as the handle 9 slides in the forward and reverse directions. The inner peripheral edge of the plate-like piece 11 is attached to the support shaft 10 by a locking part 16 that presses the plate-like piece 11 to elastically deform in the direction of the axis of the support shaft relative to the handle 9 and to get over the handle 9. 1. An operation structure for opening and closing a valve, characterized in that the arm portion is provided in a state that locks and presses.
