<p>In a synchronizing device of a transmission, in which when a coupling sleeve is slidingly moved on a synchronizer hub during gear shift operation, the coupling sleeve is engaged with a balk ring by a rotating synchronizing action, and then the coupling sleeve is further slidingly moved until the coupling sleeve is engaged with a clutch gear to complete the gear shift operation, the synchronizing device includes a guide rail mechanism, provided between the coupling sleeve and the synchronizer hub, to suppress a fall of the coupling sleeve during the sliding movement of the coupling sleeve. The guide rail mechanism is set in a sliding-movement range from a neutral position of the coupling sleeve to at least a position where a coupling-sleeve chamfer and a balk-ring chamfer abut with each other.</p> |
