Abstract
In order to achieve a good mounted state by itself without using other members such as spacers or stabilizers, an enlarged section, which is made by enlarging the inner wall of the hollow portion, is provided in the hollow of the hollow portion having the same contour shape throughout the entire length of the hollow extrudate. Thus, the regions such as the corners of the hollow portion are reinforced by said enlarged section to achieve required rigidity, i.e., position-retaining property.
