Abstract
A method of manufacturing a fluid-filled cylindrical damping assembly having sufficiently large extraction-resisting force in an axial direction of a metallic shaped product and an intermediate sleeve by the process following. There is provided a sealing rubber layer at an inner circumferential surface of the metallic shaped product having a tapered cylindrical shape where the inner flange portion is provided at an end portion of a small-diameter side. At least one concave groove is formed at an inside surface of an inner flange portion The metallic shaped product is inserted on an outer circumferential surface of an intermediate molded-body in a non-compressible fluid, and is diameter-reduced so as to be fitted and fixed. A large-diameter side end portion of the metallic shaped product is radially inwardly bent to form an engaging portion, and the engaging portion is engaged with a large-diameter side end portion of the intermediate sleeve.
