Abstract
The distal end of an endoscope is provided with at least an objective optical system and a torque transmission member for supporting a rotating treatment member. The distal end of the torque transmission member comprises a hollow to which a support axis formed in the rotating treatment member is fitted, a slit for guiding a protrusion formed on the external circumference of the support axis, and a locking member for locking the protrusion in the slit. Torque is transmitted from the torque transmission member to the rotating treatment member by means of the protrusion formed on the external circumference of the support axis of the rotating treatment member and the slit formed on the torque transmission member for guiding the protrusion.
