。 A cylinder rotatably mounted in a housing and slidably supported in the axial direction, a tip tool attached to the lower end of the cylinder, a piston fitted into the cylinder and reciprocating, and a drive motor. an intermediate shaft that transmits the rotational force of the intermediate shaft; a impact conversion device that operates in conjunction with the intermediate shaft and converts the rotational force of the drive motor into reciprocating motion of the piston; The impact tool has a movable clutch that is fitted and disengages from the impact converting device when the impact is stopped, and interrupts the interlocking movement between the intermediate shaft and the impact converting device. The tip tool is rotatably attached to the inner wall of the housing, has a protrusion in the middle, makes the protrusion come into contact with the end face of the thrust bearing attached to the cylinder, and makes the other end come into contact with the movable clutch. A striking tool characterized by being provided with a lever that pushes up the movable clutch and engages the movable clutch with the impact conversion device when the cylinder is slid in the axial direction by pressing the movable clutch against the workpiece. .
