A synchronizer ring is provided to increase shifting and driving comfort of a vehicle by guiding the synchronizer ring in a synchronizer ring hub reliably and precisely. A synchronizer ring of a synchronizing device(2) of a shiftable change speed gear transmission, comprises a ring member(3) having an inner frictional surface and an outer installation surface(5). The ring member is equipped with a rotation prevention member(11) integrally formed with the ring member to fix the synchronizer ring to a hollow space(9) of a synchronizer ring hub(10). In addition, a guide member(12) is formed at the ring member in a region between a gear surface(7) and a hub surface to guide the installation surface on an inner surface of the space of the synchronizer ring hub. |
