<p>PROBLEM TO BE SOLVED: To secure the total length while preventing interfering of an engage spring for biasing a roller of a one-way clutch with another member.SOLUTION: As an engage spring 24 of a one-way clutch 21 configured by curving an elastic plate material, includes: a fixed end portion 24a; a fixed end portion-side straight portion 24c; an inner curved portion 24d; a biased end portion-side straight portion 24e; an outer curved portion 24f; and a biased end portion 24b, the engage spring 24 having the long total length is disposed without interfering with another member, in a space limited between an outer member 22 and an inner member 12, stress generated on the engage spring 24 can be reduced, and durability can be improved. Further as a radius of curvature of the outer curved portion 24f is smaller than a radius of curvature of the inner curved portion 24d, the inner curved portion 24d is deformed first, so that a load is dispersed in a long distance from the inner curved portion 24d to the biased end portion 24b, and durability of the engage spring 24 can be further improved.</p> |
