Abstract
A double retainer type sprag-synchronized one-way clutch assembly includes a plurality of sprags which are arranged in an annular space defined between an inner ring and an outer ring and a pair of inner and outer sprag retainers, which are generally ring-shaped, for retaining the plurality of sprags spaced apart from one another at a predetermined pitch. 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.
