PROBLEM TO BE SOLVED: To provide a supporting structure for a power plant capable of ensuring excellent comfortability with a simple structure.SOLUTION: Both sides in vehicle width direction of a power plant 1 are elastically supported at vehicle body side respectively by a first antivibration device 4 and a second antivibration device 5. Spring constants of the first antivibration device 4 and the second antivibration device 5 in vertical direction are set at a different value each other, thus oscillation in vertical direction and swing in pitch direction in the power plant 1 may be easily linked. Since, the spring constants of the first antivibration device 4 and the second antivibration device 5 in vehicle width direction are set at the constants in which oscillation in vertical direction caused by antiresonance of the power plant 1 is reduced, swing in pitch direction may be easily made in the power plant 1 and oscillation energy in vertical direction of the power plant 1 is distributed. As a result, the vertical vibration of the power plant 1 is attenuated by a simple structure which does not adopt liquid sealing vibration insulation mounting. |
