PROBLEM TO BE SOLVED: To maintain damping performance by preventing wear and further improving coming-off resistance of a pin. SOLUTION: This vibration insulation member is provided with a cylindrical stirring part 6 which is arranged to project to sealed viscous fluid and to which the pin 11 formed at a tip and having a head part 13 with a diameter larger than that of a shaft part 12 is inserted. In the stirring part 6, a bottom large diameter part 8 to which the head part 13 of the pin 11 is fitted is formed in a bottom part, and the diameter of a cylindrical part 7 which is a portion connected to the bottom large diameter part 8 is set 17-43% smaller than that of the shaft part 12 of the pin 11. The friction coefficient of the stirring part 6 is defined to be≥4.2 and <6.3. COPYRIGHT: (C)2010,JPO&INPIT |
