PURPOSE:To sufficiently damp vibration in not only a direction orthogonal to a shaft but also a direction of the shaft. CONSTITUTION:A bush comprises a bush main unit 5, elastic annular unit 9, fluid chamber 10 formed between both the units and fluid 12 sealed in the fluid chamber 10. The bush main unit 5 is constituted of an inner cylinder 2, outer cylinder 3 and an elastic body 4 of connecting both the cylinders in one end side in the axial direction therebetween. The annular unit 9 is constituted so as to provide a baffle plate part 19 adhesively attached to both the inner/outer cylinders 2, 3 in the other end side in the axial direction therebetween to protrude to a side of the fluid chamber 10 and an air chamber 11 adjacent to the fluid chamber 10 with a thin partitioning part spaced. |
