Title:
OUTER SHELL UNIT AND METHOD OF MANUFACTURING THE UNIT
Document Type and Number:
WIPO Patent Application WO/2002/052166
Kind Code:
A1
Abstract:
A method of manufacturing an outer shell unit (10) comprising a tubular outer shell (3) incorporating a damping force generating mechanism and a knuckle bracket (7) fitted to the outer shell (3) and allowing a knuckle to be connected thereto, comprising the steps of fixing the knuckle bracket (7) to the outer shell (3) by welding after closing the bottom part (31) of the outer shell (3) by a closing working, whereby, since the bottom part is formed by the closing working, a man-hour for cutting a faucet part and a man-hour for assembling a lower cap can be reduced to increase a productivity and, since the sealability of the outer shell at the bottom part is assured by the closing working, the bottom part must not be sealed by welding to increase a productivity.
