Method of securing components together and a structural member made by said method

摘要

A method of securing two or more components together is disclosed in which one of the members is made from a thin wall tubular material that can be expanded by a hydroforming technique to cause deformation which is used to secure one or more components (11, 12, 13, 14; 111, 122, 123 and 114) to the tubular member (9, 109).
