To provide a power transmission for a hybrid vehicle which suitably restrains eccentricity from a rotation axis of a crank shaft of a damper.SOLUTION: An input shaft 16 is supported by a shaft end part 16g of an engine 14 side of the input shaft 16 being fitted in a crank shaft 14a of the engine 14 in a state of being relatively rotatable around a rotation axis Cc of the crank shaft 14a, and a shaft end part 16a opposed to the engine 14 side of the input shaft 16 is relatively and rotatably supported on a case CA of a power transmission 12 via a first needle bearing 52 and thereby is rotatably supported. Therefore, the eccentricity from the rotation axis Cc of the crank shaft 14a of a damper device 30 is suitably restrained by the input shaft 16 even though the damper device 30 attempts to decenter from the rotation axis Cc of the crank shaft 14a because the shaft end part 16g of the input shaft 16 is supported on the crank shaft 14a in a state of being relatively rotatable around the rotation axis Cc.SELECTED DRAWING: Figure 2

    【課題】ダンパのクランクシャフトの回転軸線からの偏心を好適に抑制させるハイブリッド車両用動力伝達装置を提供する。【解決手段】入力軸16は、入力軸16のエンジン14側の軸端部16gがエンジン14のクランクシャフト14aにクランクシャフト14aの回転軸線Ccまわりに相対回転可能に嵌合されて支持されると共に、入力軸16のエンジン14側とは反対側の軸端部16aが第1ニードルベアリング52を介して動力伝達装置12のケースCAに相対回転可能に支持されることにより、回転可能に支持されている。このため、ダンパ装置30がクランクシャフト14aの回転軸線Ccから偏心しようとしても、入力軸16の軸端部16gがクランクシャフト14aに回転軸線Ccまわりに相対回転可能に支持されているので、入力軸16によってダンパ装置30のクランクシャフト14aの回転軸線Ccからの偏心が好適に抑制される。【選択図】図2
