Claims

[Scope of utility model registration request]

A main body having an opening for receiving the insertion portion of the endoscope at the proximal end and a groove for accommodating a protrusion provided on the endoscope; It consists of a rotary ring having a groove with a protruding slope, and a biasing means for biasing the rotary ring in one direction with respect to the main body, and the rotation is performed against the biasing force of the biasing means. A connection mechanism that rotates a ring to enable the projection to be engaged, and when the projection is inserted to a predetermined position, rotates the rotary ring by the urging means to fix the endoscope. and a solid lubricant layer is formed on at least one of the urging means and the outer peripheral surface of the main body that comes into contact with the urging means when the rotating ring rotates. Connection device for endoscopy.
