PROBLEM TO BE SOLVED: To provide an endoscope treatment implement by which rotation operability in a link and a forceps piece is improved and a secondary work such as wrapping work is unnecessitated by forming a prescribed gap between the link and the forceps piece in a forceps part. SOLUTION: In biopsy forceps, the link 40 and the forceps piece 46 arranged in the forceps part are connected by a pin 44 so as to be freely rotatable. The pin is formed to have its length L1 which is longer than the one t1 plus t2 obtained by superimposing the link 40 and the forceps piece 46. Besides, a step part 62 is formed on an outer peripheral surface in the shaft part 54 of the pin 44 and is abutted on the forceps piece 46. Thus, the position of the piece 46 is restricted and the prescribed gap d1 is formed between the link 40 and the piece 46. |
