<P>PROBLEM TO BE SOLVED: To provide a sun shade having strength, which is easily manufactured. <P>SOLUTION: A sun shade is made by injection molding. The butt parts of a small triangle plate part 12b folded toward the bottom surface side of a second dihedral body 12 and a small triangle plate part 13a folded toward the bottom surface side of a third dihedral body 13 are bonded. A hollow cylindrical part 7 extending in the ridge line direction with a rhombic cross section is formed from each of small triangle plate parts 11a and 11b of a first dihedral body 11 of a first fundamental element 2 and a fourth fundamental element 5 on the opposite side thereof, each of small triangle plate parts 14a and 14b of a fourth dihedral body 14 on the opposite side thereof, and each of small triangle plate parts 12b and 13a folded toward the bottom surface side of the second and the third dihedral bodies 12 and 13 of the first fundamental element 2 and the fourth fundamental element 5 on the opposite side thereof. <P>COPYRIGHT: (C)2013,JPO&INPIT |
