Abstract
A ratchet wrench stop member positioning arrangement having a stop member mounted in a transversely extended side hole in the body thereof and forced by a spring member into engagement with peripheral teeth of a ratchet wheel in a box in one end of the body, wherein the longitudinal central axis of the side hole defines with the horizontal line which passes through the center of the box a container angle at about 8˜18° so that the angle of action produced between the stop member and the ratchet wheel during the operation of the ratchet wrench is minimized, reducing the formation of inactive componenet of force.
