Abstract
A drive unit vibration damping support for use in an electric motor-driven vehicle combines the following structural features. A subframe construction in which a drive unit is supported in vibration damping fashion on a subframe through a first vibration damping device, and the subframe is supported in vibration damping fashion on a vehicle through a second vibration damping device. A total spring constant of the first vibration damping device in a direction of input of torque reaction force of the drive unit is larger than a total spring constant of the second vibration damping device. An average value of a distance between a torque roll axis of the drive unit and the second vibration damping device is greater than an average value of a distance between the torque roll axis and the first vibration damping device.
