PURPOSE:To increase the durability of a rubber mounting, by crosswise communicating each liquid chamber of the liquid sealed rubber mounting and generating restoring force in a direction opposite to the external force in a roll direction so as to decrease the displacement in the roll direction. CONSTITUTION:When an engine 5 tends to rotate, for instance, in a clockwise direction, a right bottom rubber mounting 10' is compressed by tilting engine supporting left and right brackets 6, 6', and liquid in a liquid chamber 13' of said rubber mounting 10' is allowed to flow in a communication pipe 40 and into a liquid chamber 23 of a left upper rubber mounting 20. Accordingly, a pressure in the liquid chamber 23 rises, and restoring force, causing the engine to rotate in a counter clockwise direction, acts on the brackets 6, 6'. A left bottom rubber mounting 10 is compressed by this restoring force, and liquid in a liquid chamber 13 is allowed to flow into a liquid chamber 23' in a right upper rubber mounting 20' through a communication pipe 30. In this way, a pressure in the liquid chamber 23' rises, and restoring force, forcing the engine to rotate clockwise, acts on the brackets 6, 6', thus the damping action is obtained. |
