An operation member fixing mechanism includes: a plate member, an elastic member including a facing region, a protruding portion, a fixing lever, and a fixing knob. The protruding portion has a predetermined rigidity so as to allow the facing region to separate from the plate member when a compressed state is switched to a released state with a fixing lever and a fixing knob. The operation member fixing mechanism further includes a lubricant layer for reducing a sliding resistance of the protruding portion to the plate member in the released state and a cutout portion formed by cutting a contact surface of the facing region, the contact surface being a surface to be in contact with the plate member.

Operation member fixing mechanism and endoscope

The disclosed technology is directed to an endoscope having respective first and second operations, a movable member, respective support and friction members, a cam member and a click mechanism all of which are engaged with one another to operate the endoscope during an operation. First and second operation members are disposed in the endoscope and are rotationally operated around a predetermined axis to carry out operation of the endoscope. A movable member is disposed inside the first operation member and is movable between a first position and a second position. A cam member having a cam surface that is made with an inclination with respect to the predetermined axis and abuts against part of the movable member. A click mechanism holds the cam member at the first position or the second position.
