A hybrid transaxlethat is a transmission is provided with a junction surfacethat contacts a junction surface of an internal combustion engine. A bolt span portionof the junction surfaceis provided with a protrusion portionthat elastically deforms so that the internal combustion engine-side junction surface and the hybrid transaxle-side junction surfaceclosely contact each other.

Fastening structure of power unit

A power transmission device is provided with: a first gear having a plurality of teeth that share an identical tooth profile; an intermediate gear that is engaged with the first gear; and a second gear that is engaged with the intermediate gear, and has a plurality of teeth that share an identical tooth profile, wherein the first gear and the second gear have an identical number of teeth, an identical reference diameter, and an identical reference pitch; and the tooth profile of the first gear is different from that of the second gear.

Power transmission device

A transaxle includes a case having an opening, a second rotating electric machine stored in the opening of the case and having a stator, a rear planetary gear stored in the transaxle case and connected to the second rotating electric machine, a transaxle rear cover sealing the opening and a bolt fixing the second rotating electric machine to the transaxle case. The stator has first and second thrust end faces defining an axial length thereof. The first thrust end face is pressed against an inner surface of the case.
