<P>PROBLEM TO BE SOLVED: To provide a support structure of a power plant, a vehicle and a vibration reducing method thereof, capable of reducing vehicle body vibration, by reducing the vibration transmission ratio in starting and stopping, by switching a constitution of the support structure of the power plant in a mode in ordinary operation, starting and stopping of an internal combustion engine. <P>SOLUTION: This support structure 1 of the power plant supports the power plant 10 constituted of the internal combustion engine 11 and a transmission 12 by a fixing base 40 of the vehicle. The constitution of the support structure in starting and stopping of the internal combustion engine 11 is constituted so as to change to a second support constitution 20+30 different from a first support constitution 20 in the ordinary operation of the internal combustion engine 11 and to reduce a natural frequency of a system formed of the power plant 10 and the second support structure 20+30 in the second support constitution 20+30 to be smaller than a natural frequency of the first support constitution 20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
