PROBLEM TO BE SOLVED: To provide a link fixation structure of an operation lever for endoscopes which enables the link fixation of the operation lever on a rotary spindle being firmly stabilized without spoiling the disassembly workability of the operating part.
SOLUTION: A protruded end part 71 of the rotary spindle 7 is made trapezoidal having an inclined surface (72) gradually tapered to its protruded end side while a non-circular fitting hole 51 having an inclined surface 52 in contact with the wall 72 of the inclined surface of the protruded end part 71 of the rotary spindle is formed in the operation lever 5 and in a state fitted together, the protruded end face 71a of the rotary spindle 7 gets sunk from the surface 5a, on the side of the protruded end, of the operation lever 5. A headed screw 9 inserted into a washer 8 arrayed on the surface 5a on the side of the protruded end of the operation lever 5 is tightened into a thread hole 74 formed in the protruded end face 71a of the rotary spindle 7 to gets the washer 8 elastically deformed being pressed with a head part of the headed screw 9, thereby forcing the operation lever 5 to be fixed on the rotary spindle 7 in place.
