ABSTRACT:
A ratchet wrench apparatus includes a housing body having a lever portion extending outwardly from one side thereof to apply a torque force. A gear assembly received in the housing consists of a universal gear, planetary gears and a sun gear which are rotatably driven in unison in response to a torque force exerted through a ratchet gear adjustably disposed in the handle and housing. An output torque force is transmitted from the gear assembly through a rotor body which is normally held in interlocking relationship with the sun gear in the gear assembly. The apparatus further includes a separate selector bar element which may be manually inserted in the gear assembly to enable the rotor body to rotate independently of the sun gear when a torque force is being exerted through the lever and remaining gears.
