Abstract
An automatic shift apparatus including a rotation shaft, a dog clutch gear shift mechanism, and a control unit. The control unit supplies a predetermined electric current to a shaft moving apparatus to move a sleeve in an engaged state engaged with one of a first clutch ring and a second clutch ring and supplies a braking electric current smaller than the predetermined electric current to the shaft moving apparatus to exert a braking force on the sleeve, the braking force directed in the opposite direction relative to a direction of movement of the sleeve, before a spline of the sleeve disengages from a first dog clutch portion or a second dog clutch portion of the mentioned one of the first clutch ring and the second clutch ring.
