上記防振ゴム体内には液を封入した密閉空間を形
成し、上記内筒にはその軸方向中間位置に上記外
筒の内周よりも小径の隔壁を一体に設けて、上記
隔壁の外周と外筒内周間を自由に密封液が流通で
きる流路となし、上記隔壁の外周部両面あるいは
軸方向で上記密閉空間を区画形成する端壁に仕切
壁を立設して各仕切壁の弾性変形可能な先端を、
上記端壁あるいは上記隔壁外周部にそれぞれ小間

壁で囲まれた一対の液室を形成し、大振幅振動入
力時に相補的に変形する上記両液室間を上記仕切
壁先端を押し拡げて密封液が流通することにより
振動の減衰をなす液封入防振マウント。 A vibration-proof rubber body is provided between the inner and outer cylinders arranged concentrically,
A sealed space containing liquid is formed in the vibration isolating rubber body, and a partition wall having a smaller diameter than the inner circumference of the outer cylinder is integrally provided in the inner cylinder at an axially intermediate position thereof, and the outer circumference of the partition wall and the inner cylinder are integrally provided. The inner periphery of the outer cylinder is made into a flow path through which the sealing liquid can freely flow, and partition walls are provided upright on both sides of the outer periphery of the partition wall or on the end walls defining the sealed space in the axial direction, thereby increasing the elasticity of each partition wall. Deformable tip,
A pair of liquid chambers are formed by opposing the end wall or the outer periphery of the partition wall with a small gap therebetween to form a pair of liquid chambers surrounded by the partition wall, the end wall, and the partition wall, and the liquid chambers deform complementary to each other when a large amplitude vibration is input. A liquid-filled anti-vibration mount that attenuates vibrations by spreading the tip of the partition wall between the liquid chambers and allowing sealing liquid to flow between the liquid chambers.
