Vibration insulator having bracket

Abstract

vibration insulator is provided which includes a vibration insulator section having an outer cylinder, a rubber member which is vulcanization-bonded to the inner peripheral surface of the outer cylinder and an inner cylinder supported by the rubber member, and a bracket for supporting the vibration insulator section, with the thickness of the bracket material being made as small as possible. The bracket is composed of a pair of sheet-metal bracket members holding the axial ends of the vibration insulator. The bracket members include plate-like base sections axially opposed to each other, cylindrical sections which extend axially outward from the base sections and into which the end portions of the outer cylinder are forced, abutting sections extending radially inward from the end edges of the cylindrical sections and abutting the end surfaces of the outer cylinder and joint sections joining the bracket members to each other. A method of manufacturing the vibration insulator bracket is also provided.
