PURPOSE:To aim at reducing the cost of a bushing charged with liquid, and to prevent uncomfortable noise and vibration, by providing, in a pocket, a stopper means extended from the outer cylinder side to the inner cylinder side with a predetermined space to the inner cylinder, and coated with a resilient material. CONSTITUTION:Pockets 6 are formed between an outer cylinder 2 and a recess which is formed in a middle cylinder of a resilient member 5 at the position of an window part. An orifice groove 9 is formed in the resilient member 5 layer fixed to the outer periphery of the middle cylinder 3 so as to be used as a communication hole 7 communicated with a plurality of pockets 6 while noncompressive fluid 8 is charged in the pockets 6 and the communication hole 7. Further, a stopper means 10 composed of a rigid member 11 coated with the resilient member 5 is disposed in each pocket 6 extending from the outer cylinder 2 with a predetermined space to an inner cylinder 1. During the noncompressive fluid 8 flowing from one of the pockets 6 into the other pocket 6 through the communication hole 7, damping action is effected. |
