To provide an impact tool capable of reducing the load transmitted to a user holding the tool body. [Solution] The impact tool 1 comprises a tool body 10, a tip tool 20 attached to the tip of the tool body 10 and moving back and forth to repeatedly come into contact with the workpiece W and apply an impact force, and a cylindrical support portion 30 protruding forward from the tool body 10. The tool body 10 is pressed against the workpiece W via the support portion 30, and when the tool body 10 is driven in this state and the tip tool 20 moves back and forth, the tip of the tip tool 20 moves back and forth between a position where it protrudes relative to the support tip portion 31 of the support portion 30 and a retracted position, making it possible to repeatedly apply an impact force to the workpiece W.

The present invention provides a driving tool. A gas spring driving tool that uses the gas pressure of a pressure storage chamber as a thrust for driving has a drive return mechanism that causes a wheel portion to engage with a rack of a driver and moves an impact piston upward. When the impact piston starts to move downward from the top dead center, a large friction force is applied to the final engaging portion of the wheel portion through the rack. Therefore, it is necessary to improve the wear resistance of the final engaging portion of the wheel portion. When the impact piston (4) moves upward (D) and downward (B) relative to the top dead center, the second engaging portion (33a) that engages with the second rack (13) of the driver (11) is used as a special engaging portion for large friction force. Only the high strength and wear resistance of the second engaging portion (33a) of the second wheel portion (33) are ensured. Accordingly, compared with the case where the wheel mechanism including the first engaging portion (32a) of the first wheel portion (32) is made stronger or more wear-resistant as a whole, it is possible to achieve low cost and improve the maintainability during replacement.
