Second Stage
When synchronizer keys (4) are prevented by the
synchronizer ring (7) from sliding, the synchronizer keys
(4) are disengaged from the shifter (5). The synchronizer
keys (4) go into the grooves provided on the
synchronizer ring (7), however, since the width of the
grooves is wider than that of the keys, the synchronizer
keys begin rotating at the same speed with the shifter (5)
and coupling (3) with a time lag. In the meantime, the
shifter (5) in tis sliding direction and the synchronizer ring
(7) in its rotating direction press each other at their
chamfered portions to synchronize the synchronizer ring
(7) speed with the gear (8) speed.

Final Stage
When the shifter (5) speed becomes the same as the
gear (8) speed, the force of the synchronizer ring (7) in
its rotating direction is not applied to the shifter (5) and
the synchronizer ring (7) rotation is no longer transmitted
to the shifter (5). Therefore, the shifter (5) engages with
the synchronizer ring (7) and further engages with the
gear (8) for complete connection.
