PROBLEM TO BE SOLVED: To effectively reduce a vibration when an accelerator pedal is turned on/off by setting of a mount of a power unit, in an automobile horizontally supporting to a car body the power unit integrally setting an engine and a manual transmission. SOLUTION: Among a side engine mount M1 supporting a power unit P to a car body, a transmission mount M2, a front engine mount M3, and a rear engine mount M4, the side engine mount M1 most distant from a differential center line L serving as the swivel center in a longitudinal direction of the power unit P is constituted by generating damping in the longitudinal direction, and a frequency maximizing damping in the longitudinal direction of this side engine mount M1 is set to a range of 1.5 Hz to 7 Hz conformed to a frequency of vibration generated when an accelerator pedal is turned on/off.
