    • A spring seat of a suspension for an automotive vehicle, which is capable of preventing occurrence of noises and preventing buckling deformations thereof has a spring seat body composed of an elastic rubber body. The spring seat body is interposed and pressed between a coil spring and an opposed member. This spring seat body has a plurality of non-through holes which are formed so as to be directed toward a first surface of the spring seat body from a second surface located on the side of the opposed member, and which have openings on the side of the second surface. In addition, the spring seat body has air passages connecting the non-through holes with the surface of the spring seat body other than the second surface on the side of the opposed member.

    • 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.

    • A fluid-filled vibration damping bushing including an inner tubular metal member and an outer peripheral sleeve elastically connected via a base rubber interposed therebetween with first and second fluid chambers formed therein. A stopper rubber constituted as a separate element from the base rubber, disposed at a circumferential location corresponding at a minimum to either the first or second fluid chamber, for restricting relative displacement of the inner tubular metal member and outer tubular metal member in an axis-perpendicular direction. The stopper rubber is formed separately from an orifice member and bonded to one axial end portion of the outer tubular metal member at a location outside the first and second fluid chambers so as to face toward the inner tubular member. The outer tubular metal member with the stopper rubber attached thereto is inserted onto the outer peripheral sleeve from the other axial end thereof.
