Claims

[Claims for Utility Model Registration] 1. First and second rotating members that are spaced apart in the radial direction, are arranged concentrically so as to be relatively rotatable, and have annular raceways that extend in the axial direction, and are arranged between them. In a sprag type one-way clutch comprising a sprag that transmits torque between the raceway surfaces, and an annular retainer having radial through holes for holding the sprag at equal circumferences, the sprag is , first and second end portions that respectively engage the raceway surfaces of the first and second rotating members, and a constriction portion provided between the first and second end portions and constricted in the circumferential direction. The circumferential width of at least a portion of the through hole is smaller than the maximum circumferential width of the first and second ends and sufficiently larger than the circumferential width of the constricted portion. Sprag type one-way clutch. 2. The one-way clutch according to claim 1, wherein the retainer consists of two separate members. 3. The sprag type one-way clutch according to claim 1, wherein the retainer has means for opening the through hole at an axial edge thereof. 4. The sprag type one-way according to claim 1, wherein the circumferential width of the through hole gradually increases from near the inner or outer circumferential surface of the cage toward the inner or outer circumferential surface. Clutch. 5. The sprag according to claim 1 of the utility model registration, characterized in that at least one of the circumferential edges of the through hole is provided with a protrusion that protrudes in the circumferential direction and into the through hole. Type one-way clutch.
