Patent ID: 7963353

Claim:
A power output device of a hybrid vehicle outputting power to a driving shaft, comprising: an engine generating power using fuel combustion energy as a source; a power transmission device combining the power generated by said engine with power generated by a rotating electrical machine and transmitting the combined power to said driving shaft; a power control unit including a switching element and a reactor, for power conversion between a DC electric power from a power source and an AC electric power driving and controlling said rotating electrical machine by a switching operation of said switching element; a case coupled to said engine to allow transmission of vibration, and housing said power transmission device and said power control unit; and an anti-vibration device suspending said engine and said case on a vehicle body such that a direction of vibration of said engine and a direction of vibration of said anti-vibration device are in substantially the same direction providing absorption of relative vibration between said engine and the vehicle body, wherein said anti-vibration device has an elastic body allowing vibration, coupled between said engine, said case, and said vehicle body, and provided such that a direction of vibration of said elastic body is approximately the same as a direction of vibration of said reactor when power is conducted, and wherein said anti-vibration device is provided such that said elastic body and said reactor overlap in a vertical plane and vibrate approximately on one same line.
