Claims

[Scope of utility model registration request]

In an air hammer that vibrates the surface of an object to be cleaned, such as a casting, with a piston that can reciprocate at high speed by supplying compressed air, there is a gap parallel to the axial direction of the piston around the cylinder cap through which the tip of the piston is inserted and removed. Attach the spacer piece and adjust the length of the spacer piece in the axial direction from a neutral point near the tip of the piston that balances the push-up force to return it into the cylinder and the protrusion force to push it against the object to be cleaned during the piston stroke. This is an air hammer with a spacer, which is characterized by a long extension toward the side of the object to be cleaned.
