<P>PROBLEM TO BE SOLVED: To provide a metal foil structure which enables various types of engagement of metal foil moldings. <P>SOLUTION: An engagement part 1 includes a first recession 8 formed in a first metal foil molding 5 and a second recession 9 formed in a second metal foil molding 6. The shape of the first recession 8 is formed so that a projection area of an inside shape of the second recession 9 with respect to the first metal foil molding 5 may be larger than an opening area in the first metal foil molding 5, and the shape in the first metal foil molding 5 and a cross section parallel to the first metal foil molding 5 in the inside shape may have circular shapes. The shape of the second recession 9 is almost similar to the shape of the first recession 8. When the outer surface of the second recession 9 is fitted to the inner surface of the first recession 8, the second recession 9 turns unable to come off on the inner surface of the first recession 8 and comes free to rotate. Further, the first metal foil molding 5 comes integrated with the second metal foil molding 6. <P>COPYRIGHT: (C)2013,JPO&INPIT |
