PROBLEM TO BE SOLVED: To obtain a high productivity in the production of a strut type outer shell unit. SOLUTION: In the production method of the strut type outer shell unit 10, a processing line of an outer shell 3, which forms the outer shell 3 by machining a pipe material, and a welding line of the outer shell unit 10, which mounts a spring guide 6 and a knuckle bracket 7 onto the outer shell 3 are provided. The processing line closes the bottom of the outer shell 3 by a closing process, and the welding line rapidly welds the knuckle bracket 7 onto the outer shell 3 by a vertical position, downward welding so that a cycle time to form an outer shell 3 on the processing line nearly corresponds to a cycle time to build up an outer shell unit 10 on the welding line. |
