ABSTRACT:
The present invention provides a wrench having a handle integral with a ratchet head. The ratchet head defines a chamber having a generally circular sidewall. An annular rotor having radial teeth about an outer surface thereof is located in the chamber. The rotor teeth engage a set of teeth extending radially inward from the sidewall of the chamber. A biasing element, such as a leaf spring, is provided to urge the rotor teeth into engagement with the sidewall teeth. Preferably, the sidewall teeth will be configured having progressively increasing heights in the direction in which the rotor turns during ratcheting.
