Abstract: An endoscope treatment tool includes a sheath; a support part; a pair of forceps members that are arranged in front of the sheath and are supported so as to be relatively rotatable around a rotation shaft provided at the support part; a linear member that is inserted through the sheath so as to be capable of advancing into and retracting from the sheath, brings opposed surfaces, which are respectively provided closer to distal end sides of the pair of forceps members than the rotation shaft, closer to each other as the linear member is separated from the rotation shaft, and separates the pair of opposed surfaces from each other as the linear member approaches the rotation shaft; an elastic member that is supported by the linear member or the support part; and a locking portion that is provided on the linear member or the forceps members.
