Abstract:
A vibration isolating bushing comprising:an inner cylinder; an outer cylinder disposed and spaced apart from the inner cylinder; a rubber elastomer interposed between and interconnecting the inner cylinder and the outer cylinder by vulcanization forming; the inner cylinder integrally including at its one axial end a flared portion; said flared portion being formed by ironing an edge surface of said inner cylinder and thus enlarging said edge surface, an outer circumferential surface of said flared portion gradually expanding radially outwardly and downwardly; said outer cylinder including a main body portion and a flange portion provided at one end thereof and extending radially outwardly, said flange portion forming a surface adapted to be pressed when said outer cylinder is press fitted into a support member therefor; an outer diameter of said flange portion being larger than a largest diameter of said flared portion; and an inner diameter of said main body at said one end of said outer cylinder being smaller than said largest diameter of said flared portion, whereby when the elastomer fails, further release of the outer cylinder from inner cylinder at said one axial end of the inner cylinder is prevented by the flared portion.
