<p>The support structure (20) of an anvil pin in a cam-type inpact wrench has a feature in that the distance between centers of the concave grooves (23) in the axial direction in the hammer in which the anvil pin (24) slides to reciprocate is set to be larger than the lumen (22) of the hammer so that the cylindrical anvil pin (24) does not move in the radial direction of the hammer, whereby the anvil pin (24) is not influenced even if the cam release spring (35) rattles a little. <IMAGE></p> |
