PROBLEM TO BE SOLVED: To restrict vibration transmission and acoustic transmission in the full direction of a three-dimensional space by providing a spring mechanism absorbing load action in the vertical direction in a bearing provided with a rubber elastic support body, a coupling plate for coupling a vibrator to a bearing, and a housing for supporting the bearing on the part of one device. SOLUTION: A bearing 1 is made of a rubber elastic support body 2 provided with a coupling plate 3 to be coupled to an engine of the passenger car at the upper part thereof and a housing 4 to be support on the car body, and a spring mechanism 6 is provided as a spirally shaped spring so as to surround a cylindrical part formed at the lower part of the coupling plate 3 in a screw 5 formed at the coupling plate 3. This spirally shaped spring 6 is arranged apart from a bearing stand 7, and the bearing stand 7 supports a side wall 8 of the sectional U shape housing 4 in the outer shell thereof. Preferably, the spirally shaped spring 6 is arranged inside a work chamber 9 so that this work chamber 9 communicates with the restraint fluid in a compensation chamber 10 formed beneath the bearing stand 7 via an annular groove 11. |
