First Stage
An effort to place the shuttle lever to change the
direction causes the shifter (5) and synchronizer keys (4)
to move slightly.
synchronizer key (4) presses the holder 2 (3) against the
plates (9) and discs (8). The frictional force generated at
the plates (9) and discs (8) rotates the holder 2 (3),
holder 1 (2) and gear (1).

Second Stage
When synchronizer keys (4) are prevented by the
holder 2 (3) from sliding, the synchronizer keys (4) are
disengaged from the shifter (5). The synchronizer keys
(4) fixed in the grooves provided on the holder 2 (3),
however, since the width of the grooves are wider than
that of the keys, the synchronizer keys begin rotating at
the same speed with the holder 2 (3) and holder 1 (2)
with a time lag. In the meantime, the shifter (5) has
sliding direction toward the holder 2 (3) in its rotating
direction press each other at their chamfered portions to
synchronize the holder 2 (3) speed with the holder 1 (2)
and gear (1) speed.
