Abstract
A vibration insulating device for preventing vibration from being transmitted from an engine to a vehicle body in an automotive vehicle. The vibration insulating device is comprised of an elastic support member bonded between an inner cylinder connected to the engine and an outer cylinder connected to the vehicle body. The elastic support member is formed with a hollow which is located on an upper side of an imaginary horizontal plane containing the axis of the inner cylinder. The hollow functions to prevent a considerable tensile force from being applied to the elastic support member. Two small liquid chambers are formed between a part of the elastic support member and the inner periphery of the outer cylinder, and located on a lower side of the imaginary vertical plane. The two small liquid chambers communicate through an orifice passage. Additionally, one of the two small liquid chambers is adjacent to an air chamber through a flexible diaphragm.
