PROBLEM TO BE SOLVED: To improve the calking force of a pierce nut when the pierce nut is struck into a plate-like wall of a hollow aluminum alloy extruded section from the inside of the hollow and thereby locked against the plate-like wall. SOLUTION: A thick portion 17 having a larger plate thickness than other portions of the plate-like wall 11a is formed at a portion of the plate-like wall 11a of the aluminum alloy extruded section 11 into which the pierce nut 12 is struck. The pierce nut 12 is struck into the thick portion 17. COPYRIGHT: (C)2010,JPO&INPIT
