  • Patent number: 9976618
    Abstract: A cylindrical vibration-damping device including: an inner axial member; an outer cylindrical member; and a main rubber elastic body connecting the inner axial member and the outer cylindrical member. A pair of protruding portions are provided that protrude from the inner axial member on both sides thereof in an axis-perpendicular direction, and each protruding portion has a tapered shape thinning out toward its tip, and elastic connecting portions are constituted by the main rubber elastic body that connect both faces in a thickness direction of each protruding portion of the inner axial member to respective opposing faces of the outer cylindrical member.
    Type: Grant

  • Patent number: 9200690
    Abstract: A cylindrical vibration-damping device wherein an outer cylindrical member is made in a configuration of two sections divided along an circumference, the outer cylindrical member being externally fitted onto intermediate rings in a non-adhesive manner by means of having the intermediate rings sandwiched by the outer cylindrical member in a radial direction, and a plurality of regulating protrusions protruding inward in the radial direction are formed on the outer cylindrical member at a given distance and arranged on both sides of the intermediate rings in an axial direction so as to provide a positioning member that positions the intermediate rings with respect to the outer cylindrical member in the axial direction by means of abutting the intermediate rings against the regulating protrusions in the axial direction.
