立できる。As described above, in the present embodiment, the stopper member 6 is fixed to the vibration-proof rubber body 1 by joining, so that the strength as the stopper is improved. In addition, the partition member 3, the rubber film 2, and the cap member 8 are sequentially fitted to the cylindrical portion 11 of the vibration-proof rubber body 1 to complete the assembly, and the outer peripheral portion 81 of the cap member 8 and the vibration-proof rubber body 1 Between the cylindrical portion 11 and the partition member 3
In addition, since the rubber film 2 is held, the sealing performance can be ensured and the detachment can be prevented. Further, the positioning pin 15 of the vibration isolating rubber body 1, the pin hole 72 of the bracket 7, and the linear portion 83 of the cap member 8 facilitate positioning and assembling, thereby improving stopper strength and simplifying the manufacturing process. .

る。Further, since the bracket 7 on the vibrating body side is inserted and disposed between the stopper member 6 and the vibration isolating rubber body 1, the bracket 7 from the vehicle body side member to which the cylindrical holder 5 is attached is mounted. Can be set low. Therefore, it is advantageous when the height between the mounting members is restricted, and since the stopper member 6 has an inverted U-shape, a sufficient space for inserting the bracket 7 can be secured.
