Abstract: A shift device has lever members. These top portions engage with cut-off portions of a hub, being inserted in a groove portion of a shift sleeve. Slanted surfaces of the sleeve contact with the top portions to be capable of transmitting axial pressing force on the pressure-receiving surfaces of the ring. Friction torque acts on the members through first projections of the ring. The members has first slide surfaces contactable with first guide surfaces of the hub at both end portions in a rotational direction of the top portions, and second slide surfaces contactable with second guide surfaces of the hub at both end portions of the members.
