摘要：
An endoscopic treatment tool includes a sheath inserted into a treatment tool insertion channel of an endoscope； a treatment portion which is capable of protruding and retracting from a distal end of the sheath； a manipulation main body fixed to a proximal end of the sheath； a slider which is fixed to the treatment portion and advances and retracts in a longitudinal axis direction with respect to the manipulation main body to cause the treatment portion to protrude and retract from the sheath； a first locking mechanism which locks the slider at a position at which the distal end of the treatment portion is accommodated in the sheath in accordance with a retracting manipulation of the slider； a second locking mechanism which is provided at further distal side than the first locking mechanism and restricts advance of the slider by being locked to the manipulation main body； a fixing mechanism provided in the second locking mechanism and fixed to the manipulation main body by sliding with respect to the manipulation main body； and a restricting portion which restricts fixing of the fixing mechanism to the manipulation main body.
