ABSTRACT:
A ratchet tool includes a housing having an oval inner peripheral surface, and a core rotatably engaged in the housing for forming two curved slots between the housing and the core. The curved slots each includes two narrower end portions and a wider middle portion. Two pairs of wedges are slidably engaged in the curved slots and are biased to engage with the narrower ends for allowing the housing to drive the core. The wedges may be selectively moved toward the wider middle portions for allowing the housing to be rotated relative to the core in a reverse direction.
