きるからである。2. Description of the Related Art For example, as shown in FIG. 6, one end of an inner cylinder 100 is bent (flanged up).
A vibration isolator having 00A and connecting the inner cylinder 100 and the outer cylinder 101 with rubber 102 is well known. The reason why the inner cylinder is flanged up is that, since the inner cylinder is mounted on the mating side on the flange surface, even if a prying input is applied, the mounting portion does not rattle and the prying rigidity can be increased.

久性の低下をもたらす虞れもある。In such a method of manufacturing a vibration isolator, when the rubber and the inner and outer cylinders are vulcanized and formed, the flange 100A and the end of the outer cylinder 101 interfere with each other, and the die is cut out of this portion. Can not do. Also, it is being considered to use a medium that can be divided to form the middle part.
This leads to increased manufacturing costs. Further, for example, as shown in FIG. 7, when the middle mold is made to come off, there is a possibility that when a load is applied, cracks or the like are generated from the β portion due to concentration of stress and durability may be reduced.

1 shows a method of manufacturing a vibration isolator according to the present invention. In this method of manufacturing a vibration isolator, as shown in FIG.
First, an inner cylinder 1 having a flange 1A is formed, and a rubber 2 previously formed into a predetermined shape is bonded to the outer peripheral surface of the inner cylinder 1 by vulcanization.

い。勿論、これら双方に塗布するようにしてもよい。Next, as shown in FIG. 2, the inner cylinder 1 to which the rubber 2 has been vulcanized is bonded to the previously formed outer cylinder 3 by post-adhesion. That is, an adhesive is applied to the outer peripheral surface of the rubber 2, and the assembly including the inner cylinder 1 and the rubber 2 is
The outer tube 3 is fitted and bonded inside. The outer diameter of the rubber 2 and the inner diameter of the outer cylinder 3 are formed so as to have a small gap so that the adhesive applied at the time of this fitting is not stripped off. 3 is drawn so as to reduce the diameter, and the two are brought into close contact with each other to produce the vibration isolator shown in FIG. In addition, when the rubber 2 is vulcanized and bonded to the inner cylinder 1, the molding die can be easily removed. Therefore, the end of the rubber 2 in the axial direction is manufactured into a shape corresponding to α.
When it is fitted and adhered to the outer cylinder 3, a burring α is formed. In this embodiment, a two-component epoxy resin adhesive is used as the adhesive 4 used for the post-adhesion. Specifically, for example, FUS manufactured by LOAD CORP of the United States is used.
100% by weight of OR320 (main agent) and FUSOR31
OB (curing agent) is used in an amount of 40% by weight. In this embodiment, the adhesive is applied to the outer peripheral surface of the rubber 2 as shown in FIG. 2, but may be applied to the inner peripheral surface of the outer cylinder 3. Of course, you may make it apply | coat to both of these.

Thus, a vibration isolator having the same curvature as that shown in FIG. 3 can be formed. Also in this case, the application surface of the adhesive may be the inner peripheral surface of the rubber 2 or may be applied to both surfaces.

頼度の高いものが提供できる。As described above, according to the present invention, at least one of both ends of the inner cylinder has a flange bent toward the outer peripheral direction, and the rubber and the inner cylinder are vulcanized and adhered. A rubber adhesive is applied to at least one of the outer peripheral surface of the rubber and the inner peripheral surface of the outer cylinder to be bonded to the rubber, thereby fixing the rubber and the outer cylinder, or vulcanizing and bonding the rubber and the outer cylinder to each other. Since a resin-based adhesive is applied to at least one of the inner peripheral surface of the inner cylinder and the outer peripheral surface of the inner cylinder to be joined to the rubber, the rubber and the inner cylinder are fixed to each other. There is no need, and the manufacturing cost can be reduced accordingly. Also, even without using such a divisible medium size, since the α portion which enters the outer cylinder can be formed and secured, the generation of cracks and the like can be effectively prevented, and a material having high reliability over a long period of time can be obtained. Can be provided.
