Abstract
The present invention comprises a ratchet wrench which has a pawl and spring arrangement such that the pawl's rotational movement is limited when out of engagement with the ratchet wheel so as to assure that the spring does not become disengaged from the pawl to render the wrench inoperative. The spring is provided with a pivotal action which eliminates loading on the end of the spring and provides more desirable spring action.
