Abstract
A vehicle power transmission device is disposed on a hybrid vehicle having an engine and an electric motor, the vehicle power transmission device includes a first member having one of outer circumferential teeth disposed around one axial center or inner circumferential teeth meshing with the outer circumferential teeth and a second member having the other teeth, the inner circumferential teeth and the outer circumferential teeth meshes with each other to limit relative rotation around the one axial center between the first member and the second member, the relative rotation between the first member and the second member is limited to transmit torque of the electric motor to drive wheels. The vehicle power transmission device comprises: a sliding member sliding relative to at least one of the first member and the second member while generating frictional resistance as the first member and the second member relatively rotate within a range corresponding to a circumferential gap between the outer circumferential teeth and the inner circumferential teeth, the sliding member being a hollow elastic body, the sliding member sliding relative to at least one of the first member and the second member depending on magnitude of the torque of the electric motor.
