Abstract
In a gear synchronizer mechanism including a gear member rotatable on a shaft and having a cylindrical hub portion, a hub member mounted on the shaft for rotation therewith, a clutch sleeve formed at its one side with an internal conical surface and at its inner periphery with internal spline teeth in continual engagement with external spline teeth of the hub member and being axially shiftable on the hub member to be engaged at its internal spline teeth with external spline teeth of the hub portion, and a synchronizer ring formed with an external conical surface for frictional engagement with the internal conical surface of the sleeve and being axially movable on the hub portion to establish synchronization between the shaft and the gear member when engaged with the sleeve, a plurality of leaf springs are disposed within a plurality of circumferentially equally spaced radial recesses defined in the hub portion and engaged with the synchornizer ring in such a manner as to restrict axial movement of the synchronizer ring by engagement therewith in shifting operation of the clutch sleeve.
