At least one of the inner and outer sprag retainers is fabricated from a plastic material or the like and includes a plurality of axial sections arranged circumferentially and a plurality of circumferential sections, each of which connects the corresponding ends of two axial sections alternately in side to thereby define a serpentine-like structure.
