Claims

[Scope of utility model registration request]

A piston is reciprocated via a crank mechanism by a prime mover such as a motor, a cylinder is rotatably supported within a main body frame and guides the piston, and the cylinder is slidable within the cylinder to open an air chamber. a striking element that is reciprocated by the piston through the cylinder, and a rotation locking part located on the opposite end of the cylinder from the piston, forming a second air chamber together with the striking element and the inner wall of the cylinder; and an intermediate striker that is locked at the cylinder and movable in the axial direction of the cylinder within a limited range, wherein a large gap is provided between the cylinder and a rotation locking portion of the intermediate striker. A striking tool characterized by:
