ABSTRACT:
A one-way sprag clutch is composed of a first and second races arranged concentrically and rotatably relative to each other with a radial interval and having axially-extending annular race surfaces respectively, sprags arranged between the first and second races to transmit torques between the race surfaces, and an annular retainer defining through-holes maintaining the sprags with equal angular intervals. Each of the sprags is formed of a first and second end portions engageable respectively with the race surfaces of the first and second races and a constricted portion extending between the first and second end portions, is constricted in an angular direction and has a cross-section substantially in the form of a peanut shell. The angular width of at least a part of each of the through-holes is narrower than the maximum angular widths of the first and second end portions but is broader than the angular width of the constricted portion.
