が圧縮され、シリンダ外の圧力より高圧になる位
置に穿設して成る打撃装置。 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, and the striker and the inner wall of the cylinder Forming a second air chamber, to a limited extent,
In a striking device including an intermediate striker installed movably in the cylinder axial direction, a plurality of air holes are bored in the cylinder wall, and the first air hole is connected to the middle striker when the intermediate striker approaches the piston side. The second air hole is drilled in a position where it is closed when it moves to the opposite side, and is opened when it moves to the opposite side, and the second air hole is moved until the striking element contacts the intermediate striking element that is closer to the piston side. When the air in the second air chamber is compressed, the impact device is bored at a position where the pressure becomes higher than the pressure outside the cylinder.
