Patent ID: 7581721

Claim:
A cylindrical vibration isolating device comprising: an inner cylinder having an outer peripheral wall; an outer cylinder arranged outside of the inner cylinder, said outer cylinder having a pair of projecting portions spaced apart by a predetermined distance in an axial direction and projecting from an inner peripheral wall of said outer cylinder towards said outer peripheral wall of said inner cylinder; and an elastic body having a compressed portion and being positioned between said inner cylinder and said outer cylinder, wherein, during mounting of the outer cylinder, said elastic body is compressed between said outer peripheral wall of said inner cylinder and said projecting portions thereby forming the compressed portion, and wherein said inner cylinder has said outer peripheral wall in which a radius of curvature of said outer peripheral wall of said inner cylinder is larger than a radius of curvature of said outer cylinder such that a space between said inner cylinder and said outer cylinder gradually narrows toward each end portion in a circumferential direction of said outer cylinder, and slits are provided at positions where the space between said outer peripheral wall of said inner cylinder and outer cylinder are narrowed.
