CYLINDRICAL VIBRATION-PROOFING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a cylindrical vibration-proofing device having a new structure in which an axial spring constant can be set high through a compact structure and a degree of freedom of setting spring ratios of an axial perpendicular direction and an axial direction is increased.SOLUTION: Inner protrusions 24 and 24 protruded to an outer peripheral side are partially provided except a set of bore holes 30 and 32 on the periphery at an axial outer end part of each of inner axial members 16 arranged in series and outer protrusions 28 and 28 protruded to an inner peripheral side are partially provided except a set of bore holes 30 and 32 on the periphery at an axial inner end part of each of outer axial members 18 arranged in series, and in turn each of main body rubber resilient bodies 20 is provided with a pair of rubber arms 38 and 38 resiliently connecting the inner axial member 16 and the outer axial member 18 to each other between peripheral directions of the set of bore holes 30 and 32, and the pair of rubber arms 38 and 38 are arranged and fixed between the inner protrusions 24 and 24 and the outer protrusions 28 and 28.
