Title:
METHOD FOR MANUFACTURING ANTI-VIBRATION UNIT
Document Type and Number:
WIPO Patent Application WO/2013/021715
Kind Code:
A1
Abstract:
A method for manufacturing 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 (11) of an anti-vibration device (10) is pressed into a press-fitting section (35) of a second bracket (30) so as to be firmly fixed. Thus, compared to the situation in which the boss member (11) of the anti-vibration device (10) is firmly fixed (fastened) with a bolt to the second bracket (30), 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 (11) of the anti-vibration device (10), thus enabling a corresponding reduction in man-hours during manufacturing. In addition, when chemically treating the boss member (11) of the anti-vibration device (10), 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.
