摘要： An impact-driven tool includes a cylinder and a piston slidably inserted into the cylinder and has a large-diameter portion. The cylinder includes: a chamber on one end side; a chamber on the other end side; a communication path that allows the chamber on one end side and the chamber on the other end side to communicate with each other; and a valve chamber that is continuous with one end side in the axial direction of the communication path, and a valve body for piston lifting control that is incorporated so as to be movable up and down and is provided in the valve chamber.
