PURPOSE:To make a vibro-isolating rubber device possible to function so effectively, by elastically supporting an assembled body of an engine and a transmission with the vibro-isolating rubber device at a proper supporting point in relation to both rolling and pitching motions. CONSTITUTION:An assembled body 52 of an engine 50 and a transmission 51 is elastically supported at its both end parts with each of vibro-isolating rubber devices 53-56 on an inertia main shaft Ir for a rolling motion and another inertial main shaft Ip for a pitching motion. In addition, these vibro-isolating rubber devices, in time of car running, energizes a solenoid coil 20 with a continuous rating current, closing an open passage 11 with a valve element 16, and each of chamber spaces 6 and 8 is interconnected through via another open passage 10 whereby the occurrence of an engine shake and a stuffy noise is reduced. Likewise, in time of idle running, the open passage 11 is opened and thereby idling vibrations are effectively reduced. Doing like this, these vibro- isolating rubber devices are made to function so effectively. |
