トレンチ。[Scope of Claim for Utility Model Registration] (1) In an impact wrench that tightens bolts, etc. using rotational force generated by a power source such as air pressure, a hammer case that is rotated by the power source, and the hammer case. It consists of an output shaft with one end inserted inside through a bearing, and at least two magnet pieces are disposed on each of them, and the magnet pieces of the hammer case and the output shaft are arranged in positions facing each other, Further, the magnetic hammer type is characterized in that the polarities of the magnetic pieces on the opposing surfaces are all the same, and a magnetic piece positioning mechanism is provided for moving the magnetic pieces relative to each other in the axial direction. impact wrench. (2) A patent claim characterized in that the magnetic piece positioning mechanism is an output shaft positioning device that makes the output shaft to which the magnetic piece is fixed movable in its axial direction and rotatably supports the output shaft at an appropriate position. The magnetic hammer type impact wrench described in item 1. (3) Claim 1, characterized in that the magnet piece positioning mechanism is a mechanism that allows the magnet piece provided in the hammer case to move in its axial direction and fixes it to the hammer case at an appropriate position. Magnetic hammer type impact wrench described in .
