Abstract: It is an object of the invention to provide a technique that contributes to realizing both the switch selecting function and the handle vibration-proofing function, in an impact tool which can switch an operation mode of a tool bit. An impact tool includes a motor 111, a tool body 103, a handle 109, a vibration-proofing cushioning material 161 which connects the tool body 103 and the handle 109 such that the tool body and the handle can move with respect to each other. The impact tool further includes a motor-driving manual operating member 143 disposed on the handle 109, an operation mode switching member 151 disposed on the tool body 101, and a movable member 153. When the operation mode switching member 151 is switched to first operation mode in which the tool bit 119 is continuously driven, the movable member 153 moves the manual operating member 143 from an off position to an on position and locks it in the on position. When the operation mode switching member 151 is switched to second operation mode in which the tool bit 119 is arbitrarily driven, the movable member 153 releases the lock of the manual operating member 143. A vibration-proofing elastic member 143c is disposed in an arbitrary region in the vibration transmitting path. The elastic member 143c prevents vibration caused in the tool body 103 from being transmitted to the handle 109 via a vibration transmitting path in the state in which the manual operating member 143 is locked in the on position by the movable member.

Abstract: The present invention realizes effective recoil reduction and idling strike prevention with a minimum constitution. In a tool holder (6), a thermal-resistant O-ring (22) is arranged between two steel washers (21,23) near the joint to the barrel (5). The O-ring (22) has a cross-sectional diameter of approximately 7 mm. The inner diameter of the O-ring (22) is made slightly greater than the diameter of a cylindrical portion (19b) formed at the rear of an intermediate element (19) and slightly smaller than the diameter of a flange (19a) formed at the rear of the cylindrical portion (19b). Likewise, the inner diameter is made slightly greater than the diameter of a recess (18b) of a striking member (18) formed in front thereof and slightly smaller than the diameter of a flange (18a) formed in front of the recess (18b). The cylindrical portion (19b) of the intermediate element (19) is extended backward for such a distance that, when the cylindrical portion (19b) is fitted in the O-ring (22), the flange (19a) is positioned behind, and out of contact with, the O-ring (22).

Abstract: An airflow regulation arrangement for regulating the impact of the strikes delivered from a striking member (6) to an intermediate member (10) and a bit, thus reducing the vibration, and also for regulating the impact of recoils of the striking member (6) is disclosed for use in an electrical hammer (1). The airflow regulation arrangement comprises an air inlet (14) provided in an air chamber (5) in a cylinder (3) of the electrical hammer (1), exhaust ports (15) provided in a second air chamber (9), and air passages (16) in communication with the air inlet (14) and the exhaust ports (15). The air passages (16) are connected to choke passages (17), the cross sectional area of which is one fifth to one sixth of that of the air passages (16). In a forward stroke of the striking member (6), the compressed air forced out of the second air chamber (9) is gradually released out of the cylinder (3) after passing through the air passages (16) the choke passages (17), which causes a gradual pressure increase in the second air chamber (9) as the striking member (6) moves forward, thereby appropriately braking the striking member (6) and checking the excessive acceleration and the impact of the strikes of the striking member (6).
