Abstract: A rotary electric machine, a transmission, and a differential gear device are disposed coaxially. The transmission includes a first helical gear and a second helical gear that meshes with the first helical gear. A case includes a first case member including a stator support portion that supports a stator of the rotary electric machine, a second case member that is structured as a separate member from the first case member and forms a gear chamber that houses the transmission and the differential gear device, and a support member that supports the first helical gear in an axial direction. The support member rotatably supports a rotor of the rotary electric machine via a rotor bearing, and is fixed to the second case member.

Abstract: In a vehicle drive device, a first drive device configured to drive a first engagement device configured to connect or disconnect power transmission between an input member and a first rotor includes a first shift drum and a first cam mechanism. A second drive device configured to drive a second engagement device configured to connect or disconnect power transmission between the first rotor and an output member includes a second shift drum and a second cam mechanism. The first shift drum and the second shift drum are coaxially disposed and connected via a drum drive shaft so as to rotate integrally. The vehicle drive device includes a drum drive source configured to drive the drum drive shaft.

Abstract: A first rotating element is a first sun gear that rotates with a rotor. A third rotating element is a first ring gear connected to a case. A fourth rotating element is a second ring gear that rotates with an input element. A second rotating element is a first carrier rotatably supporting a first pinion gear and a second pinion gear that rotate together. The first pinion gear meshes with the first sun gear and the first ring gear. The second pinion gear has a smaller diameter than the first pinion gear and meshes with the second ring gear. The first sun gear is supported in a radial direction with respect to the case via a first support bearing. The second ring gear and the input element are connected such that their relative movement in the radial direction is restricted.
