Vibration damper including polyamide-resin member covered by elastic layer, and method of producing the same

摘要

A vibration damper of composite type including a vulcanized-rubber body formed of a vulcanized rubber material and a polyamide-resin member formed of a polyamide resin material. The vulcanized-rubber body and the polyamide-resin member are integrally bonded together, and the exposed surface of at least the polyamide-resin member is covered by a coating layer formed of an elastic material with a predetermined thickness. Also disclosed is a method suitable for producing the vibration damper, wherein a solution of an unvulcanized rubber material or a thermoplastic elastomer is applied to the exposed surface of at least the polyamide-resin member, and is subjected to a vulcanizing or drying operation to form the coating layer.
