PROBLEM TO BE SOLVED: To provide a single-shot air hammer tool which though simply structured, is capable of minimizing the wearing-out of components, and converting the pressure of compressed air into the force of advancing the hammer without attenuation of the pressure, and the hammer of which is always fixed in the home position when in a resting state.SOLUTION: A partially notched annular body 80 is arranged in a predetermined position which faces a hammer 76 placed in a stop position α in a cylinder 6, and a part of the partially notched annular body 80 projects toward the interior of the cylinder 6. In addition, a recessed groove 77 is arranged in a position opposite the partially notched annular body 80 of the hammer 76 in the stop position α. When the recessed groove 77 is locked in the partially notched annular body 80, the hammer 76 is placed in the stop position α in the interior of the cylinder 6. |
