Abstract:
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.
