構成して成る打撃装置。 A crank rotated by a motor, a piston reciprocally driven by the crank, a cylinder that guides the piston, and an air chamber that is slidable within the cylinder and that is formed by the piston and the inner wall of the cylinder. a striker that is reciprocated by air pressure in an air chamber that changes with the reciprocating motion of the piston; and a striker located at an end of the cylinder opposite to the piston, the striker and the inner wall of the cylinder In a striking device comprising an intermediate striking element that forms a second air chamber and is installed movably in the cylinder axial direction within a limited range, a plurality of air holes are bored in the cylinder wall, and a plurality of air holes are formed in the cylinder. The diameter d2 of the second air chamber to be formed is larger than the diameter d1 of the first air chamber, and guide portions are formed at both ends and approximately in the center of the striking element, so that the intermediate striking element is connected to the piston. When the striking element is on the side, when the striking element passes through the second air hole, it compresses the second air chamber, and when the intermediate striking element moves in the opposite direction, the outer periphery of the striking element and the second air hole are compressed. The second air chamber is configured to be electrically conductive and the second air chamber is opened, and the central guide portion of the striking element is configured so that it does not deviate from the first air chamber diameter d1 even if the intermediate striking element moves toward the side opposite to the piston. A striking device made of
