ABSTRACT:
A spring-locked variable speed pulley, such as may be used as a drive device for automotive, motorcycle or industrial applications, wherein the engagement of a spring with the side of a stopper and movable pulley piece are improved in such a manner that the pulley can be used in a wide variety of applications. The movable pulley piece is mounted on a shaft adjacent to a stationary pulley piece with the movable pulley being movable axially as well as being rotatable. A stopper and a spring are interposed between the movable and fixed pulley pieces. Pins protrude from the side of the confronting surfaces of the movable pulley piece and the stopper, which pins engage in holes formed in the ends of the spring, the holes being disposed diametrically opposite one another with respect to the center longitudinal axis of the spring.
