摘要：
A vibration insulating device to be installed between two members of a vibration system of an automotive vehicle. The device consists of an annular elastic member disposed between coaxial inner and outer cylindrical members and located coaxial with the outer cylindrical member. The elastic member is formed at its outer peripheral surface with a deep annular groove coaxial with the outer cylindrical member which groove is covered with the outer cylindrical member to define an annular hollow chamber. A generally cylindrical flexible diaphragm member is secured between the outer cylindrical member and the elastic member in such a manner that its central annular section divides the hollow chamber into a radially outward gas chamber and a radially inward liquid chamber, thereby effectively absorbing even high frequency small amplitude vibration transmitted to the device under deformation of the flexible diaphragm member.
