Treatment tool for endoscope

A treatment tool for an endoscope comprising:

• an insertion part that has a distal end part, which is provided with an openable and closable grip part, and a bendable part, which is provided adjacent to the distal end part and is bendable, and that is insertable into a body;
• an operating part into which an operation of closing the grip part and an operation of bending the bendable part are input;
• and
• a transmitting part that transmits the operations of the operating part to the grip part and the bendable part,
• wherein the operating part has an operating member that is movable in a first direction parallel to a longitudinal axis of the insertion part and a second direction orthogonal to the first direction,
• the transmitting part has
• a follower member that is movable only in the first direction among the first direction and the second direction,
• a cam member that is movable only in the second direction among the first direction and the second direction and drives the follower member in the first direction in response to a movement of the cam member in the second direction,
• a first transmitting member that extends from the operating member to the insertion part, and
• a second transmitting member that extends from the follower member to the insertion part,
• the operating member and the cam member have engaging parts respectively that allow a relative movement in the first direction and prevent a relative movement in the second direction by engaging with each other,
• the grip part is closed as one of the first transmitting member or the second transmitting member is moved in the first direction, and
• the bendable part is bent as other of the first transmitting member or the second transmitting member is moved in the first direction.
