    • Disclosed herein is a driving state switching unit with a synchro-mechanism which employs a synchro-mechanism to perform switching of a driving state. The switching unit is equipped with a first gear (32) and a second gear (33) coaxially disposed, a gear connecting member (34) axially movable so that the first gear (32) and the second gear (33) can be connected, and a synchro-mechanism (35) interposed between the first gear (32) and the second gear (33). By moving the gear connecting member (34) by an electric actuator (50), the first gear (32) and the second gear (33) are connected, while they are being synchronized by the synchro-mechanism (35). When this occurs, control means (102) controls a supply current to the electric actuator (50), and judgement means (102) judges synchronization of the synchro-mechanism (35), based on a change in the supply current value to the electric actuator (50). With this, the judgement of the synchronization of the synchro-mechanism (35) is made possible without providing dedicated sensors, switches, etc., and an accurate judgement, corresponding even to an individual difference in the sliding resistance between members and a change in running conditions, is made possible.
