Abstract
A ratchet tool includes a shaft and a handle to which a direction selection collar is mounted and a ratchet member is received in the handle. The ratchet member has inner toothed periphery and two pawl members engaged with the inner toothed periphery. The ratchet member has three dents defined in one of two ends thereof and the direction selection collar has a positioning member embedded therein which is movably received in one of the dents when rotating the collar. The collar has a rod extending between the two pawl members, the rod pivoting one of the pawl member to disengage from the inner toothed periphery by rotating the collar.
