A multi-stage transmission includes both a drive and a driven gear shaft. A plurality of driven gears are mounted on the driven gear shaft for engagement and disengagement from the driven gear shaft individually by an engaging member that is changed over to make a gear shift. The engaging member includes swing pawl members swingably supported by pivot pins on the driven shaft. End parts of the swing pawl members, extending from the pivot pins are engaging claw parts engageable with engaging surfaces of engaging projections formed on the inner circumferential surfaces of the driven gears. The other end parts of the swing pawl members are acted upon to be pushed up by pin members which are operated to be advanced and retracted by gear shifting operation. The pin members operate to release engagement of the engaging claw parts with the engaging projections of the driven gears.
