Zusammenfassung:	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.
