PROBLEM TO BE SOLVED: To suppress tooth rattling noise occurring in a power transmission system of a hybrid vehicle.SOLUTION: A power transmission system of a hybrid vehicle comprises an engine, a first motor, a second motor, a first drive gear connected to the first motor, a counter driven gear connected to a drive axle, and a second drive gear connected to a rotor shaft 3b of the second motor via a connection part 16, in which the first drive gear and the second drive gear mesh together with the counter driven gear. In a connection structure of rotary members in the power transmission system of the hybrid vehicle, the connection part 16 is formed of a connection shaft 18 which is formed on a motor output shaft 3c integrated with the second drive gear, and a connection hole 19 formed in the rotor shaft 3b, convexities 20 are formed on the outer periphery of the connection shaft 18, concavities 21 fitted with the convexities 20 are formed in the inner periphery of the connection hole 19, and the center position of the connection shaft 18 is offset from the center position of the connection hole 19.SELECTED DRAWING: Figure 2

    【課題】ハイブリッド車両の動力伝達系統で発生する歯打ち音を抑制すること。【解決手段】エンジン、第1モータ、第2モータ、第1モータに連結された第1ドライブギヤ、駆動軸に連結されたカウンタドリブンギヤ、および、連結部16を介して第2モータのロータ軸3bに連結された第2ドライブギヤとを備え、カウンタドリブンギヤに第1ドライブギヤおよび第2ドライブギヤが共に噛み合うハイブリッド車両の動力伝達系統における回転部材の連結構造において、第2ドライブギヤと一体のモータ出力軸3cに形成した連結軸18と、ロータ軸3bに形成した連結穴19とから連結部16を構成すると共に、連結軸18の外周部に凸部20を形成し、連結穴19の内周部に凸部20と嵌まり合う凹部21を形成し、連結軸18の中心位置と連結穴19の中心位置とをオフセットする。【選択図】図2
