PURPOSE:To improve the vibration absorbing performance of the engine body by obtaining the nonlinear spring characteristic fitted with the vibration characteristic of the engine body by installing a hollow member inside a stopper rubber which is formed thinner towards the top edge. CONSTITUTION:A mount rubber 2 is fixed between an upper metal fitting 7 for a stopper which has a power-unit installation screw 6 planted and a lower metal fitting 9 having a chassis installation screw 8 planted. A stopper rubber 12 for preventing the swing of the upper metal fitting 7 over a prescribed degree is fixed onto the lower metal fitting 9. The stopper rubber 12 is formed thinner towards the collision top edge part, and a hollow member 14 is buried, and the spring characteristic is the nonlinear characteristic in which the slope varies in three stages. Therefore, both of the swing preventing effect for the engine body and the vibration absorbing performance can be achieved. |
