Description of the Related Art Engineering plastics are widely used as a substitute material for metals because of their excellent mechanical strength, heat resistance, oil resistance and creep resistance. Also in the field of composites composed of rubber and metal such as anti-vibration rubber, thermoplastic resin materials such as engineering plastics have been adopted as materials replacing metal. For example, a vibration-proof rubber used for an automobile engine mount or the like is also being changed from a conventional metal bracket to which rubber is vulcanized and bonded to a synthetic resin bracket to which rubber is bonded.
