PROBLEM TO BE SOLVED: To provide a hybrid-vehicular power transmission apparatus capable of improving NV performance by improving configurations of a damper mechanism and a torque limiter.SOLUTION: A hybrid-vehicular power transmission apparatus have: a damper mechanism 10 for absorbing a torsional vibration with elasticity of a damper spring 10a; a torque limiter 12 for limiting transmission torque between an engine and a drive shaft; a sun gear 6 of a planetary gear mechanism 4 connected to a first motor 2; a ring gear 7 connected to counter gears 16, 17 and a drive shaft 5 via a first drive gear 14 that is meshed with the counter gear 16; and a carrier 8 connected to the engine 1 via the damper mechanism 10. Further in the apparatus, the ring gear 7 and the first drive gear 14 are separately disposed and connected integrally via the torque limiter 12, and the damper spring 10a is disposed on an at-most outer circumference of the damper mechanism 10 and in a direction of the spring expanding-compressing in the circumferential direction of the damper mechanism 10.SELECTED DRAWING: Figure 2

    【課題】ダンパ機構およびトルクリミッタの構成を改良して、NV性能を向上することができるハイブリッド車両の動力伝達装置を提供することこと。【解決手段】ダンパばね10aの弾性によってねじり振動を吸収するダンパ機構10と、エンジンと駆動軸との間で伝達トルクを制限するトルクリミッタ12とを備え、遊星歯車機構4のサンギヤ6が第1モータ2に連結され、リングギヤ7がカウンタギヤ16と噛み合う第1ドライブギヤ14およびカウンタギヤ16,17を介して駆動軸5に連結され、キャリア8がダンパ機構10を介してエンジン1に連結されたハイブリッド車両の動力伝達装置において、リングギヤ7と第1ドライブギヤ14とを別体で構成すると共に、トルクリミッタ12を介して一体に連結し、ダンパばね10aを、ダンパ機構10の最外周側でダンパ機構10の円周方向に伸縮する向きに配置する。【選択図】図2
