A reversible ratchet wrench includes a ratchet body having a round head portion with a cylindrical, internally toothed opening therethrough forming a ratchet gear and defining a cavity. A ratchet mechanism, including a drive body, a pawl assembly and a reversing member, is disposed in the cavity, with the reversing member secured to the drive body for confining the pawl assembly therebetween. The head of the ratchet body has annular shoulder surfaces thereon respectively at opposite ends of and coaxial with the cavity, and respectively facing annular shoulder surfaces on the drive body and reversing member, for cooperation therewith to define first and second annular spaces, in which are respectively disposed annular seal members, each having a pair of radially inwardly extending and axially diverging flexible and resilient lips, respectively engageable with the shoulder surfaces defining the associated space for cooperation therewith to seal the cavity and center the ratchet mechanism on the head.
