Patent ID: 8651468

Claim:
A tubular vibration-damping mount comprising: a core member; a tubular member located below the core member and having an inside diameter larger than an outside diameter of the core member; a rubber member located between the core member and the tubular member to couple the core member and the tubular member by vulcanization adhesion, an upper surface of the rubber member having, as viewed in a cross section including an axis of the core member, a recessed portion in a radially inner direction of the rubber member and an inclined portion whose inclination angle is smoothly and upwardly increased in the radially inner direction from a point on the tubular member as a starting point; and a bracket supporting an outer periphery of the tubular member with the tubular member being inserted; wherein the tubular member has, in an area higher than a lower end of an adhesion surface between the tubular member and the rubber member, a straight cylindrical portion which has an inner periphery and an outer periphery, both of which are parallel to an axis of the tubular member and a diameter-enlarged portion which has an inner periphery extending from an upper end of the straight cylindrical portion and smoothly enlarging the inside diameter of the tubular member and the starting point is on the inner periphery of an outside diameter enlarged portion of the tubular member, and wherein the diameter-enlarged portion has a largest outside diameter larger than a diameter of the straight cylindrical portion and an outer periphery of the diameter-enlarged portion comprises a surface whose diameter is smoothly increased from the outer periphery of the straight cylindrical portion; and the bracket comprises a guide portion having an inside diameter larger than the largest outside diameter of the diameter-enlarged portion and a constant inside diameter portion located above the guide portion and having a constant inside diameter smaller than the largest outside diameter of the diameter-enlarged portion, the constant inside diameter portion engaging the outside diameter of the straight cylindrical portion to support the tubular member.
