WIPO Patent Application WO/2021/117867

Kind Code:

A1

Abstract:

[Problem] To realize a structure with which the transmission route of motive power can be switched by an electric actuator. [Solution] On the basis of the rotation of a drive cam 50, a motive power transmission route switching device 5 switches between: a first mode in which a friction engagement device 40 is connected and a rotation transmission state switching device 41 has been switched to a free mode; a second mode in which the friction engagement device 40 is disconnected and the rotation transmission state switching device 41 has been switched to a lock mode; and a switch mode in which the rotation transmission state switching device 41 has been switched to a one-way clutch mode, the switch mode being established during switching from the second mode to the first mode.
