Abstract
A ratchet wrench has a through cavity in which a reversing lever is disposed. The reversing lever has a pair of protruding lips formed thereon opposite from one another. A cooperating ledge is formed on the head in the cavity and on the pawl which is adjacent to the reversing lever. A spring-loaded pusher is disposed longitudinally in a blind bore in the reversing lever and the pusher engages a pocket in the pawl. A cover plate is disposed on a shelf recessed on the bottom of the wrench and spaced apart from the reversing lever.
