PROBLEM TO BE SOLVED: To provide a cylindrical vibration isolating mount with the load applied in the axial direction having such a structure that a shaft member and an outer cylinder member are resiliently coupled together by a cylindrical rubber piece interposed between them, in which the durability of the cylindrical rubber piece is enhanced. SOLUTION: An outside diameter changing part 31 is provided on the peripheral surface near the bottom of a shaft member 12 where a cylindrical rubber piece 15 is mounted so that the bottom part in the axial direction of the shaft member 12 is reduced in the diameter, and also a ring-shaped boring part 40 in a groove shape formed at the bottom surface in the axial direction of the rubber piece 15 is arranged so that the tensile force generated with elastic deformation of the rubber piece acts concentrically on the inside corner 42 of the boring part 40, and this inside corner 42 is positioned opposing to the outside diameter changing part 31 of the shaft member 12. |
