PROBLEM TO BE SOLVED: To have no limitation on resin raw material and also reduce structural and mechanical stress accumulation in a resin molding to the utmost, and further join main body parts to each other not to cause the critical discrepancy such as generation of cracks even if physical property of molding material is lowered. SOLUTION: This treatment tool for an endoscope is so constructed that the main body of an operating part is formed of synthetic resin, the mutual connecting joint end parts of a first main body member 11 and a second main body member 12 to be connected and joined to each other are provided with projecting and recessed locking parts 21-24 which are complementarily fitted and engaged with each other. Thus, the first main body member 11 and the second main body member 12 are mechanically and surely connected and joined to each other. |
