Title:
FLUID SEALED TYPE CYLINDRICAL VIBRATION-PROOFING DEVICE
Document Type and Number:
Japanese Patent JP2017187171
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fluid sealed type cylindrical vibration-proofing device of a new structure capable of stably permitting relative movement in an axial direction, of a partition rubber and an inner shaft member while securing fluid tightness between the partition rubber and the inner shaft member, in the fluid sealed type cylindrical vibration-proofing device capable of obtaining vibration-proofing effect based on a fluid flowing action to axial input vibration.SOLUTION: In a fluid sealed type cylindrical vibration-proofing device 16, an outer peripheral side of a partition 60 is fixed to an outer cylindrical member 44, and an inner peripheral side of the partition 60 is composed of an annular partition rubber 66 externally inserted to an inner shaft member 42 in a state of being axially movably, seal cylindrical portions 80, 82 projecting toward axial both sides from an inner peripheral part of the partition rubber 66 are integrally formed, and fitting portions 84, 86 thicker than the seal cylindrical portions 80, 82 at projecting tip portions of the seal cylindrical portions 80, 82, and externally fitted to the inner shaft member 42 slidably, are integrally formed.SELECTED DRAWING: Figure 1
