PURPOSE:To eliminate resistance in a torque transmission part so as to improve clutch engaging-disengaging performance and simplify structure. CONSTITUTION:A track 4 is formed between an inner wheel 1 and an outer wheel 2, and each of inner-outer wheel track faces 1a, 1b is made into a single leaf hyperboloid of revolution. Plural rollers 3 are disposed being inclined by the specified angle to the face including the centerline 5a in such a way as to be in linear contact with these inner-outer wheel track faces 1a, 2a, and there is provided a reel 6 rotatable in relation to the inner wheel 1. The outer wheel 2 is energized by a conical disk spring-like member 7 in the direction of narrowing the spacing of the track 4, and torque is transmitted between the reel 6 and the outer wheel 2. Only the conical disc spring-like member 7 is thereby deformed without generating sliding between the outer wheel 2 and reel 6, so that resistance in a power transmission part is eliminated to zero, and the structure is simplified. |
