れる。On the outer surfaces of the arm member 1 and the first and second bearing members 2 and 4 of the vibration isolating suspension device configured as described above, several types of coating such as cationic electrodeposition coating are applied. It is performed as appropriate for each part or after assembly of each part. The anti-vibration suspension device of the present embodiment configured as described above is used by being incorporated in a suspension mechanism of an automobile. In this case, an attachment shaft portion such as another connection arm or an attachment member is fitted and fixed to an inner hole of the inner cylinder fitting 31 of the vibration isolating bush 3 by bolting or the like, and the ball joint 5 is fixed.
The joint shaft 52 is connected to another connecting arm, a mounting member, or the like, whereby vibration-proof connection is achieved. As a result, the vibration generated between the vibration isolating suspension device and the connecting arm or the like connected thereto is effectively absorbed by the elastic action of the rubber elastic body 32 of the vibration isolating bush 3 or the angular displacement of the ball joint 5. .
