Abstract
Driven gears are supported on a hollow driven gear shaft in a manner engageable with and disengageable from a hollow driven gear shaft via swing pawl members. The transmission has first a engaging member for engaging the gear shaft with a first driven gear, so as to effect synchronous rotation thereof and a second engaging member for engaging the gear shaft with a second gear, one step lower in the reduction gear ratio than the first gear, so as to effect synchronous rotation thereof. When making an upshift by changing over the engaging member from the engagement with the first gear to the engagement with the second gear, the gear shift is made by engaging the second gear with the gear shaft through the second engaging member while the first gear is being in engagement with the gear shaft through the first engaging member.
