A treating instrument for an endoscopic treatment has a pair of treating members at the distal end of a sheath. The treating members are opened or closed in a beaklike manner by a control wire axially movably inserted in the sheath. A pair of links of different lengths are integrally connected to the treating members, respectively. A pair of intermediate links of different lengths are rotatably connected at one end thereof to the pair of links, respectively, and driven at the other end thereof by the control wire so as to move back and forth. The shorter intermediate link is connected to the longer link. The longer intermediate link is connected to the shorter link.
