とする打撃工具。 In a striking tool that operates by a crankshaft rotated by a motor via a gear, a piston interlocking with the crankshaft, and air pressure fluctuations caused by the reciprocating motion of the piston, the striking tool sliding part in the piston is formed in a cylindrical shape. A through hole is provided at the end in the direction perpendicular to the tool axis, a semi-cylindrical sleeve is press-fitted into the through hole, and a spherical resin engagement member having a cylindrical through hole in the center is slidably inserted into the sleeve. A projection provided eccentrically on the crown portion of the crankshaft is fitted into the cylindrical through hole of the engagement member, and the crown portion of the crankshaft is disc-shaped and forms a sliding surface with the piston. A striking tool characterized by:
