る。By the way, it is necessary to fix by caulking or pressing as in the prior art, because the caulking portion (lower end portion 9) receives a large load. However, by adopting such caulking and pressing processes, high caulking and pressing parts are required to have high dimensional accuracy, and complicated machining processes are required. Moreover, since the number of parts is relatively large, it is difficult to significantly reduce the cost. Therefore, the present application solves such a problem.

固定したことを特徴とする。In order to solve the above-mentioned problems, a liquid-sealing vibration isolator according to the present application is provided with a first connecting member attached to either the vehicle body side or the vibration member side and a first connecting member attached to the other. Two connecting members, an elastic block provided between these two members, and a liquid chamber formed by at least a part of the elastic block, and a part of the wall of the liquid chamber is separated from the elastic body. In the liquid-sealing vibration isolator formed of the elastic film, the first connecting member and the second connecting member are integrally connected by an elastic block to form a main body, and an elastic film mounting portion provided on the main body is attached. The elastic film is fixed by a press-fitting fixing member.

Also, the degree of compression of the elastic film can be changed by changing the amount of press-fitting of the fixing member.

幅なコストダウンが可能になる。Since the first connecting member and the second connecting member are integrally connected by the elastic block to form the main body portion, a large input load is received by the main body portion. Therefore, since the load applied to the elastic film is much smaller, even if the elastic film is press-fitted into the elastic film attachment portion of the main body, the fixing structure is necessary and sufficient for use. Therefore, when fixing the elastic film, it is sufficient to press the fixing member into the elastic film mounting portion of the main body, and the caulking and pressing can be eliminated. As a result, the dimensional accuracy required for caulking and pressing is not required. And the processing steps are simplified. In addition, the number of parts is relatively small, which enables a significant cost reduction.

Therefore, by simply changing the amount of press-fitting of the fixing member, the dynamic spring of the elastic film is changed. The characteristics can be adjusted easily. Moreover, in the case of the type in which the orifice is formed in the compression portion of the elastic film, the orifice characteristic can be easily adjusted in the same manner.
