Connection of two pieces to make a component using a shoulder and component produced

摘要

The method involves forming shoulder portions (13,14) in the region of connecting surfaces (33,33') of the to-be-connected components (4',7'), so that a gap (10) is provided between to-be-connected components. The central axis (28) of the gap is extended at specific angle to an outer surface (34') of the component (7'). The shoulder portions are provided at the edge of the to-be-connected components. An independent claim is included for component.
