As for the rotor of disposal tool, 1st has with the peripheral face and distance the 2nd peripheral face whose aforementioned 1st is smaller than the peripheral face to diameter direction from the longitudinal direction axis of the aforementioned flexibility tube part. Aforementioned disposal tool, the 2nd rotary manipulation wire which extending facilities is done and, has for the aforementioned 2nd peripheral face according to the 2nd rhombic direction which inclines in the aforementioned 1st peripheral face facing toward 2nd direction of rotation from the 1st rotary manipulation wire and the longitudinal direction which extending facilities are done facing toward 1st direction of rotation inclines according to the 1st rhombic direction which from the longitudinal direction.処置具の回転子は、第1の外周面と、前記可撓管部の長手方向軸からの径方向へ距離が前記第1の外周面より小さい第2の外周面とを備える。前記処置具は、長手方向から第1の回転方向に向かって傾斜した第1の斜方方向に沿って前記第1の外周面に延設される第1の回転操作ワイヤと、長手方向から第2の回転方向に向かって傾斜した第2の斜方方向に沿って前記第2の外周面に延設される第2の回転操作ワイヤと、を備える。
