Abstract:
1. A drive unit vibration damping support for use in an electric motor-driven vehicle to provide vibration damped support of a drive unit including an electric motor on a vehicle body, comprising: a first vibration damping device being adapted to support the drive unit in vibration damping fashion on a subframe; and a second vibration damping device being adapted to support the subframe in vibration damping fashion on the vehicle body, wherein a spring constant of the first vibration damping device in a direction of input of torque reaction force of the electric motor is set to a greater value than a spring constant of the second vibration damping device; and wherein an average of a distance between a torque roll axis of the drive unit and the second vibration damping device is set to a greater value as compared with an average of a distance between the torque roll axis and the first vibration damping device.
