摘要： A vibration drill unit capable of obtaining an intensive drilling force. The vibration drill unit includes a first ratchet, anon-rotatable second ratchet having a claw engageable with the claw of the first ratchet, and a main body frame for accommodating a motor, a spindle, the first ratchet and the second ratchet. The respective claws of the first ratchet and the second ratchet include the first inclined surfaces formed so as to be engaged in the rotation direction by rotations of the first ratchet and so as to be separated from each other, the second inclined surfaces having greater inclination in the reversed direction than the first inclined surfaces, top parts that link the upper parts of both inclined surfaces to each other, and flat parts that link the bottom parts of both inclined surfaces to each other.

摘要： An impact drill minimizing transmission of vibration to a handle gripped by a user's hand. A spindle extends through a main frame and is movable in its axial direction and rotatable about its axis. A first ratchet is rotatable and axially movable together with the spindle. A second ratchet is axially movable but unortatable. The first ratchet has a first serrated surface and the second ratchet has a second serrated surface in confrontation with the first serrated surface. In an impact drilling mode, the first serrated surfaces is brought into abutment with the second serrated surface so that the spindle is reciprocally moved in the axial direction. A first spring is interposed between the main frame and the second ratchet to urge the second ratchet toward the first ratchet. A second spring is interposed between the main frame and the second ratchet to urge the second ratchet away from the first ratchet. In the impact drilling mode, the second ratchet is always out of contact from the main frame and is floatingly maintained within the main frame.

摘要： An impact tool for reducing noise without lowering the tightening ability. The impact tool gives a rotary blow force to a tip tool by mounting a rotary blow mechanism on a spindle rotatably driven by a motor and intermittently transferring the rotary blow force generated by the rotary blow mechanism from a hammer to the tip tool via an anvil, damping materials absorbing at least the vibration in the radial direction are arranged on at least one side of both supports of the axial direction of the spindle 7. The damping material is interposed between a bearing that rotatably supports the rear end portion of the spindle and an inner cover that holds the same, and an O-ring is interposed as a damping material between the front end portion of the spindle and an anvil that rotatably supports the same.

摘要： An impact drill includes a first ratchet rotating along with a spindle and movable in an axial direction, a second ratchet engaged with the first ratchet and movable in a axial direction but unrotatable, and a spring provided between the second ratchet and a partial member of a housing. An amount of movement of the spindle in the axial direction is regulated, so that the pressing force is too excessive, the restoring force of the spring urging the second ratchet is controlled to maintain a state of generating a set stroke force.
