<p>A socket wrench for power tool, wherein one side of pin insert hole is closed, a connection pin is inserted into the insert hole and set so that the gravity center of the socket wrench is positioned on the closed part side of the center of the socket wrench and, as necessary, a fixing ring having a projected part is fitted onto the outer peripheral surface of the socket wrench with the projected part inserted into the insert hole for holdingly positioning, whereby, since the centrifugal force of the connection pin caused by the rotation of the socket wrench acts in the direction of the closed part, the pin can be prevented from being scattered during the rotation of the socket.</p> |
