<p>A synchronizer assembly (S) having an axially centered neutral recess (13) and on each axial side of the neutral recess a gear engaging recess (22, 23) is provided. The gear engaging recesses (22, 23) are selectively engageable by a radially outwardly biased detent member (14) mounted in a strut (3) to minimize the tendency of the detent member to escape between the end of the ring (6) and the other baulking ring (9), thereby loading the conical friction surfaces of that ring and the gear (2), thereby causing undue wear to the synchronizer assembly when the synchronizer assembly is in a gear engaging position. Preferably, the gear engaging recesses (22,23) are shallower than the neutral recess (13). <IMAGE></p> |
