PURPOSE:To effect an excellent oscillation isolating characteristic in an engine mounting device for an automobile by providing a mass plate member inside a linking body and linking the mass plate member to a supporting body via a spring member. CONSTITUTION:Supporting fittings 10, 12 are linked by a rubber elastic body 32, and a metal plate 34 as a mass plate member is provided inside it. A supporting rubber block 36 as a spring member is vulcanizedly bonded in an integrated form with the metal plate 34. And, a partition wall rubber 38 having nearly an annular plate form as a partition-wall elastic body is vulcanizedly bonded in an integrated form with the outer peripheral edge part of the metal plate 34. A resonance frequency in an oscillating system consisting of the metal plate 34 and the supporting rubber block 36 is set appropriately. Thereby, an excellent oscillation isolating characteristic can be effected. |
