Abstract
A shift device includes an output shaft, a hub, a speed gear, a sleeve, a synchronizer ring, lever members, and a spring. The lever members have torque receiving portions contactable with projections of the synchronizer ring to receive friction torque from the projections. Contact positions of the torque receiving portions and the projections in a synchronization operation are set at a hub side of the lever members and an axial-directional distance between points of support and the contact positions is less than a thickness of the lever member.
