PURPOSE:To improve the reducible effect of low and medium frequency vibrations in an engine, by setting up an inner capacity variable member, which seals gas inside and is retractable in a vibration transmission direction when a weight is secured tight to an free end, in a fluid chamber of a hydrodynamic engine mount. CONSTITUTION:An inner capacity variable member 40, which seals gas inside 41 and is retractable in a vibration transmission direction where a weight 50 is secured tight to a free end, is set up in a fluid chamber 2 of a hydrodynamic engine mount. With this, the weight 50 vibrates according to low and medium vibrations at a low, medium rotation range, and owing to this weight 50, the inner capacity variable member 40 varies its capacity so that transmission of the low and medium frequency vibrations to a car body can be sharply reduced. |
