Abstract
An endoscope treatment tool includes: a tubular sheath part; an operation wire; an arm member; a holding tube; and a biasing member. The sheath part includes an elongated body part, and a tubular member. In a state where the holding tube and the tubular member are in contact with each other, the holding tube and the tubular member are connected to each other so as not to be rotated relative to each other about an axis and to be movable relative to each other in a direction in which a central axis of the sheath part extends. The arm member and the holding tube have a rotation restricting structure that prevents the arm member from rotating about an axis of the holding tube in a state where the arm member is in contact with the holding tube against the biasing force of the biasing member.
