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 |
