ための操作口を開口した ことを特徴とするインパクトレンチ。[Scope of Claim for Utility Model Registration] A shaft rotated by driving force from a motor, and a rigid ball slidably inserted into a V-groove provided in this shaft to transmit the rotational force of the shaft to rotate the shaft. A hammer clutch is provided with an engagement groove in which the hard ball engages, and a hammer clutch is elastically biased in the forward direction by a spring. A socket holder is provided in the casing and rotates while being struck, the rotational force from a hammer clutch repulsively retracting against the hammer being transmitted through a striking protrusion provided on the outer circumferential side of the hammer clutch, and a socket attached to the socket holder is provided. In an impact wrench that tightens the tightening body while instantaneously rotating under the rotational force of the socket holder, a hammer body of a predetermined mass with thrust bearings interposed on both sides is fixed to the spring pressing surface of the hammer clutch with a screw. An impact wrench characterized in that the impact wrench can be inserted into the impact wrench, the hammer body is pressed against the hammer clutch side by the elastic force of the spring, and an operation port is opened in the casing for tightening the screw from the outside.
