PROBLEM TO BE SOLVED: To provide a suspension device of an engine which can suppress that an occupant feels incongruity due to the propagation of engine vibration to a vehicle side in a situation that it is not necessary to suppress the resonance of a vehicle.SOLUTION: When acceleration in a vertical direction in a vehicle is smaller than a determination value HG, an electronic control device switches a spring characteristic of an engine mount between a first spring characteristic and a second spring characteristic according to an engine rotational speed NE. In detail, when the engine rotational speed NE is smaller than the determination value HR, a VSV is opened so that the spring characteristic of the engine mount is switched to the first spring characteristic whose spring constant k becomes smaller than that of the second spring characteristic. Furthermore, when the engine rotational speed NE is not smaller than the determination value HR, the VSV is closed so that the spring characteristic of the engine mount is switched to the second spring characteristic whose spring constant k becomes smaller than that of the first spring characteristic.SELECTED DRAWING: Figure 3

    【課題】車両の共振を抑制する必要がない状況下において、エンジン振動の車両側への伝達により乗員が不快感を覚えることを抑制できるエンジンの懸架装置を提供する。【解決手段】電子制御装置は、車両における上下方向の加速度が判定値HG未満であるとき、エンジン回転速度NEに応じてエンジンマウントのばね特性を第1ばね特性と第2ばね特性との間で切り替える。詳しくは、エンジン回転速度NEが判定値HR未満であるとき、エンジンマウントのばね特性が第2ばね特性よりもばね定数kが小さくなる第1ばね特性に切り替えられるようVSVを開弁させる。また、エンジン回転速度NEが判定値HR以上であるときには、エンジンマウントのばね特性が上記第1ばね特性よりもばね定数kが小さくなる第2ばね特性に切り替えられるようVSVを閉弁させる。【選択図】図3
