<p>A multistage transmission (10) is provided that smoothly operates with a small force without the necessity of a shift clutch, that does not cause a loss of switching time during shifting, and that does not cause escape of a driving force as well as provides a small shift shock. When shift drive means (51,52,53) executes upshift to a one-step-upper speed-change stage reduced in reduction ratio by one stage, normal rotation odd-numbered stage cam rods (Cao) and normal rotation even-numbered stage cam rods (Cae) alternately operate normal rotation odd-numbered stage engaging members (Rao) and the normal rotation odd-numbered stage engaging members (Rae) for shifting.</p> |
