Document Type and Number:
Japanese Patent JP2016109216
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fluid-sealed vibration isolation device having a novel structure which can advantageously obtain fluid tightness of a fluid chamber or the like by simple assembling.SOLUTION: In a fluid-sealed vibration isolation device 10, a cylindrical sealing member 72 is attached to a second attachment member 18, the sealing member 72 comprises an attachment cylinder part 80 and a seal cylinder part 74 at both sides of a step part 78, respectively, a pressure-insertion protrusion 82 is partially formed on a periphery at least at either of an internal peripheral face of the attachment cylinder part 80 and an external peripheral face of the second attachment member 18, the second attachment member 18 is inserted into the attachment cylinder part 80, and pressure-insertion fixed thereto at a forming portion of the pressure-insertion protrusion 82, and a transmission prevention part 84 for reducing the transmission of stress to a transmission portion accompanied by the pressure-insertion to the seal cylinder part 74 from the attachment cylinder part 80 is arranged at the step part 78 of the sealing member 72.SELECTED DRAWING: Figure 3
