PROBLEM TO BE SOLVED: To improve the vibration damping properties of an extruded aluminum section with hollow parts. SOLUTION: A vibration damping resin 10 is inserted from the ends of the hollow parts of a section with the hollow parts, e.g. of the truss-shaped extruded aluminum section 1. Further, the vibration damping resin 10 is arranged on part or the whole of the inner surfaces of the hollow parts 7-9 in the longitudinal direction of the section, in more concrete terms, between a rib and a face plate 3. Finally, the vibration damping resin is thermally stuck to the inner surfaces of the hollow parts. |
