PURPOSE:To simplify mount assembling operation and improve workability with fluid chambers formed and sealing ensured, and need for assembling a relatively large size supporting metal fitting in fluid eliminated, by fabricating a bracket to an integrated valcanized molding. CONSTITUTION:A nearly truncated cone-like rubber elastic body 16 is formed in which a first supporting metal fitting 12 and a connecting fitting 26 are fixed to small and large diameter side end parts respectively. Also a bottomed cylindrical bracket 38, having a through hole 46 blocked with a flexible film 48, is formed on a bottom part. The bracket 38 opening part is extrapolated to the connecting fitting 26 in fluid under a condition where the flexible film 48 is inwardly pressed, and also surplus fluid is discharged outside from between the opening part and the connecting fitting 26. Moreover the bracket 38 opening part is diameter-reducedly processed to be sticked fast to the connecting fitting 26, and fluid chambers 20 and 22 are formed in the inside. Then a second supporting metal fitting 14 is caulkedly fixed to an insertion-fixing part of the bracket 38 to the connecting fitting 26 outside fluid, allowing the connecting fitting 26 to be fixed in an axis direction to the bracket 38. |
