Abstract
Balls to be moved radially outward by a centrifugal force are held in a clutch hub, and projections extending around the outer circumferences of the balls are united with a synchronizer ring. Those portions of the projections, which radially confront the balls, are formed with slopes for establishing an axial force to push the synchronizer ring away from the spline piece on the basis of the centrifugal force of the balls. Thus, the axial force for disengaging the synchronizer ring from a rotating member to be synchronized can be increased to prevent the chatter at a low number of revolution and to effectively eliminate the drag torque at a high number of revolution.
