<p>Comprises a base (80) that is inserted through the opening of a structure having a roughly C-shaped cross section and has a short side that is shorter than the width of the opening, and a nut (90) that is inserted within the base (80), has an outer circumference diameter that is bigger than the width of the opening, and has a female screw (91) in the inner circumference. The base (80) is equipped with an opened section into which the nut (90) and a male screw (60) are inserted. The nut (90), after insertion through the opened section of the base (80), is inserted within the hollow section of the structure while being held at a tilted state that is passable through the opening of the structure, the female screw (91) swings parallel to the opening to face the opening by inserting the male screw (60) through the opening of the structure into the opened section of the base (80), and by screwing in the male screw (60), the male screw (60) and the female screw (91) screw together, thereby fixing a mating member.</p> |
