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 tool, which can realize the reduction of noise without inviting the reduction of a fastening ability and which can improve the durability of a damper while preventing its damage. The impact tool includes a rotary impact mechanism mounted on a spindle to be rotationally driven by a motor, so that rotary impact is applied to a tip tool by transmitting the rotary impact intermittently from a hammer through an anvil to the tip tool. A plurality of pawls are formed on two half members of the anvil in the axial direction. A rubber damper is disposed in a space between the pawls arranged alternately in the circumferential direction of the two half members. The minimum sectional area of the space formed between the pawls is set larger than the sectional area of the rubber damper.
