PROBLEM TO BE SOLVED: To provide a fluid sealed vibration control device having a new structure capable of assuring durability even in the case that an axial static supporting load is inputted and a vibration control effect against an axial vibratory input can be effectively attained by a compact structure.SOLUTION: A main body resilient body 16 is constituted by overlapping the first rubber resilient body 56 and the second rubber resilient body 58 in an axial direction, and a pair of axis straight liquid chambers 88, 88 are formed between these overlapped surfaces. A pair of partition walls 80, 80 partitioning a pair of axis straight liquid chambers 88, 88 are constituted by overlapping the first partition wall piece 82 protruded from the first rubber resilient body 56 and the second partition wall piece 84 in a circumferential direction. In addition, the first rubber resilient body 56 is formed to be more thick and larger diameter than that of the second rubber resilient body 58 and at the same time the first rubber resilient body 56 is formed to be tapered, a static supporting load is inputted under a state in which it is installed at a vibration transmission system to cause the first rubber resilient body 56 to be compressed.

    【課題】軸方向の静的支持荷重が入力される場合にも耐久性が確保されると共に、軸方向の振動入力に対する防振効果を、コンパクトな構造で有利に得ることができる、新規な構造の流体封入式防振装置を提供すること。【解決手段】本体ゴム弾性体16が第一のゴム弾性体56と第二のゴム弾性体58を軸方向に重ね合わせて構成されて、それらの重ね合わせ面間に一対の軸直液室88,88が形成されている。更に、一対の軸直液室88,88を隔てる一対の隔壁部80,80は、第一のゴム弾性体56から突出する第一の隔壁片82と、第二のゴム弾性体58から突出する第二の隔壁片84とを、周方向に重ね合わせて構成されている。また、第一のゴム弾性体56が第二のゴム弾性体58よりも厚肉大径とされていると共に、第一のゴム弾性体56がテーパ形状とされており、振動伝達系への装着状態で静的支持荷重が入力されて、第一のゴム弾性体56が圧縮されるようにした。【選択図】図1
