To reduce rolling vibration inputted into a car body from a power unit in a wide frequency region.

A first mount point A is provided in front of and above the center of gravity G of the power unit 2, a second mount point B is provided behind and below it, and a third mount point C is provided in front of and below it to mount the power unit 2 onto a car body side at these positions. Furthermore, a vertical line L passing through the center of gravity G and a link 10 rising forward and crossing obliquely when viewed in a side view are provided. An angle θ formed by them is 60° or less. The link 10 connects a car body side mounting point D in the vicinity of the first mount point A with a power unit side mounting point E in a rear part of the power unit 2 which is on the opposite side to the mount point A and is behind the center of gravity G across the vertical line L obliquely to cancel a bending input applied to the first mount point A from the power unit 2 side by a reaction force of the link 10 at the car body side mounting point D.
