ABSTRACT:
An endoscope includes an operation portion side member, an insertion portion side member rotatable integrally with the insertion portion, an elastic member provided in one of the operation portion side member and the insertion portion side member, a frictional surface which is provided in the other of the operation portion side member and the insertion portion side member and which generates a frictional force between the frictional surface and the elastic member when the frictional surface is pressed onto the elastic member and the insertion portion is rotated, and a movement adjusting mechanism which relatively moves the operation portion side member and the insertion portion side member to continuously adjust press force acting between the elastic member and the frictional surface while deforming the elastic member.
