Vehicle drive device

A vehicle drive device comprising:

• a rotating electrical machine;
• a power control unit controlling said rotating electrical machine;
• a case housing said rotating electrical machine and said power control unit;
• a damper to which a crankshaft of an internal combustion engine is coupled;
• and
• a power transmission mechanism combining power generated by said internal combustion engine with power generated by said rotating electrical machine for transmission to a drive shaft,
• said power control unit including
• an inverter driving said rotating electrical machine,
• a voltage converter configured to have a reactor, for boosting a power supply voltage to apply the boosted voltage to said inverter, and
• a circuit element substrate on which a power element of each of said inverter and said voltage converter is mounted,
• said case is configured to integrally house said damper, said rotating electrical machine and said power transmission mechanism,
• said reactor and said circuit element substrate are disposed in said case such that, when projected in a direction of a rotation shaft, said reactor and said circuit element substrate fall within a horizontal dimension of a projected portion of said case, when mounted on the vehicle, that houses said damper, said rotating electrical machine and said power transmission mechanism, and
• said reactor including
• a core disposed to transmit and receive heat to and from said case, and
• a coil wound around said core.
