Antivibration device production method, stopper for antivibration device, and antivibration device

A stopper for an anti-vibration device that is to be used in the anti-vibration device including:

• an anti-vibration body including an inner cylinder, an outer cylinder, and an elastic body connecting the inner cylinder and the outer cylinder;
• a bracket arranged on one side of the anti-vibration body in an axial direction;
• and the stopper arranged between the anti-vibration body and the bracket, the stopper comprising:
• a rigid member having an opening formed therein;
• and
• an elastic member, wherein
• the elastic member includes a stopper body configured to cover the rigid member, and a positioning protrusion continuous with the stopper body, and
• the positioning protrusion includes a shaft portion extending to one side in the axial direction as part of the stopper body and configured to be able to penetrate a positioning hole formed in the bracket, a bulging portion continuous with an end of the shaft portion so as to be prevented from detaching from the bracket, and a coating portion provided on at least a surface of the bulging portion and configured to be peelable.
