<p>Disclosed is an extruded hollow section that can be fabricated in fewer production man-hours, and furthermore, is stable in quality. With the extruded hollow section 10, parallel parts 21, 22 each having a width in one direction within a section vertical to the direction of extrusion, being constant along the direction of extrusion, are integrally formed with tilt parts 25, 26 each having a width in the one direction, varying along the direction of the extrusion, wherein the parallel parts are integrally formed with the tilt parts. The extruded hollow section 10 is made of a light metal.</p> |
