Abstract
A ratchet wrench includes a wrench body and a switch member that is operatively coupled to a gear engaging member so as to be accessible from an exterior of the wrench body. A spring applies a biasing force to the gear engaging member such that the gear engaging member having one or more engaging teeth engages with gear teeth of a torque receiving gear in intermeshed relation. A mounting element mounts the gear engaging member to the switch element. The gear engaging member is pivotally mounted to the mounting element. The pivotal mounting of the gear engaging member enables the gear engaging member to pivot relative to the mounting element as the gear engaging member moves between a first ratcheting position and a second ratcheting position thereof. Also provided is switch securing structure for securing the switch during operation of the ratchet wrench and a method of making the ratchet wrench.
