ABSTRACT:
A manufacturing method for an outer shell unit (10) provided with a cylindrical outer shell (3) housing a damping force generating mechanism and a knuckle bracket (7) mounted on the outer shell (3) to connect a knuckle. The knuckle bracket (7) is fixed by welding to the outer shell (3) after closing the bottom (31) of the outer shell (3) with a closing process. Consequently productivity is increased due to the fact that the number of processing operations for cutting an inlay and the number of operations for assembling the lower cap are reduced because the bottom is formed using a closing process. Furthermore productivity is increased since it is not necessary to seal the bottom by welding since the sealing characteristics of the bottom of the outer shell are ensured by the closing process.
