Abstract
A parking device includes a drive cam disposed around an MG shaft that transmits a drive force of a second motor generator by being coupled with a parking gear, a driven cam disposed around an MG shaft so as to be able to rotate integrally with the MG shaft and capable of moving in the axial direction of the MG shaft by a relative rotation generated between the driven cam and the drive cam when the parking gear is locked by a pilot clutch, and a dog type brake that engages the parking gear with the MG shaft and a transaxle case accommodating the parking device by the movement of the driven cam. With the configuration, a shock load at the time of operation can be suppressed and the parking device can be reduced in size.
