1. A reversible ratchet tool, comprising:
a ratchet body having an inner surface defining a circular aperture therein;
a cage member, disposed in said circular aperture of said ratchet body, which is a ring shape integral body having a central cage aperture axially and a plurality of cage spaces formed intervally and radially, and comprising a plurality of pairs of resilient members arranged in said cage spaces respectively;
a reverser knob, coaxially coupled to said cage member, having a central aperture communicating with said cage aperture;
a driving member rotatably including an axle portion extended through said cage aperture of said cage member and rotatably retained with the reverser knob;
a plurality of rollers disposed between said ratchet body and said driving member, wherein said plurality of rollers are retained in said cage spaces of said cage member respectively, wherein said plurality of pairs of resilient members is configured to apply a resilient bias force to said plurality of rollers respectively for restricting and maintaining each of said plurality of rollers upright in place within said cage space when each of said plurality of rollers is shifted and moved along a travel path thereof from a first position to a second position thereof on said driving member; and
a reversing mechanism configured to shift said reverser knob and said driving member from a first angular displacement to a second angular displacement, wherein said cage member is adapted to shift each of said rollers from said first position to said second position thereof on said driving member when said reverser knob and said driving member are shifted from said first angular displacement to said second angular displacement.
