  • Patent number: 9523407
    Abstract: An anti-vibration unit, which enables a reduction in man-hours to be achieved during manufacturing and a reduction in the number of parts, is provided. A boss member of an anti-vibration device is pressed into a press-fitting section of a second bracket so as to be firmly fixed. The omission of the bolt enables a corresponding reduction in the number of parts. Moreover, by omitting the bolt in this way, there is no need to form a female threaded section on the boss member of the anti-vibration device, thus enabling a corresponding reduction in man-hours during manufacturing. In addition, when chemically treating the boss member of the anti-vibration device, it is unnecessary to implement a step for protecting the female threaded section with a masking bolt, thus eliminating the need to attach and detach the masking bolt, which in turn enables a corresponding reduction in man-hours during manufacturing.
