PURPOSE:To improve the productivity of a vibro-isolating bush sharply by forming it simultaneously with a rubber layer, absorbing an impact of contact among a rubber elastic body, a stopper member and an outer cylinder fitting, at time of manufacturing the vibro-isolating bush for a engine mount or the like of a fluid flow engine car. CONSTITUTION:At the time of manufacturing a fluid-sealed type vibro-isolating bush provided with a stopper part 52 consisting of a support part 54 and an extension part 58, using a support fitting 42 provided with a blade part 48 projecting sidewise and a lap 46 supporting this blade part, this support fitting 42 is solidly installed in an inner cylinder fitting 10 tightly. Afterward, vulcanization forming operation on rubber material is applied to the inner cylinder fitting 10 tightly fitted with the support fitting 42, whereby a rubber elastic body 14 is solidly formed in the inner cylinder fitting 10 by means of vulcanization. Simultaneously with this formation, the specified rubber layer is solidly vulcanized and formed in the lap 46 of the support fitting 42 and the blade part 48 being opposed to an outer cylinder fitting 12, forming the stopper part 52. Then, the outer cylinder fitting 12 is assembled to the integral vulcanized molding produced like this, thereby forming a fluid chamber. |
