Title:
METALLIC TUBE COMPONENT
Document Type and Number:
Japanese Patent JP2007209998
Kind Code:
A
Abstract:

To provide a metallic tube component the weight of which is easily lightened and which is contributable to cost reduction.

This metallic tube component is a metallic tube which is integrally formed, has two or more bent parts and has one or more bulged parts on a straight tube part between the bent parts. Consequently, such parts that have to join other parts by welding or the like previously can be also integrated and not only the improvement of fatigue strength of such components that the fatigue fracture in a welded place becomes a problem and the lightening of the weight by the reduction of the welded parts but also the effect of cost reduction or the like by reducing the number of the parts is obtained. Speaking about the parts for automotive use, the component is applicable to, for example, a body system part such as a roof rail, a chassis system part such as a suspension member and an exhaust system part such as an exhaust manifold.
