Patent ID: 7992661

Claim:
A hybrid vehicle drive device, comprising: a clutch that transmits and separates a driving force between an engine output shaft and a transmission input shaft; a first electric motor having a first rotor that is connected to an engine output shaft side member of the clutch; a second electric motor having a second rotor that is connected to a transmission input shaft side member of the clutch; an intermediate shaft, wherein the first rotor and the engine output shaft side member of the clutch are fixed so as to rotate integrally with the intermediate shaft; and a radial vibration suppressing device, wherein: (1) the intermediate shaft is connected to the engine output shaft via the radial vibration suppressing device, and (2) the radial vibration suppressing device suppresses a vibration of the engine output shaft in a radial direction, the intermediate shaft and the transmission input shaft are fitted so as to be able to rotate relative to each other, and the second rotor and the transmission input shaft side member of the clutch are supported so as to be able to rotate relative to an outer circumferential surface of the intermediate shaft.
