<P>PROBLEM TO BE SOLVED: To provide a sun shade which has high strength and is easily manufactured. <P>SOLUTION: A sun shade is an injection molded product. An abutting part of a small triangle plate 12b bent to the bottom surface side of a second dihedron 12 and that of a small triangle plate 13a bent to the bottom surface side of a third dihedron 13 are joined together. A hollow shaped cylindrical part having a rhombic cross section and extending in the ridge line direction is formed of small triangle plate parts 11a, 11b of first dihedrons 11 of a first fundamental element 2 and a fourth fundamental element 5 located at the other side thereof, small triangle plate parts 14a, 14b of a fourth dihedron 14 located at the other side thereof, and small triangle plate parts 12b, 13a bent to the bottom surface sides of second and third dihedrons 12, 13 of the first fundamental element 2 and the fourth fundamental element 5 located at the other side thereof. In the cylindrical part, through-holes 31, 34 are formed which are used to connecting the sun shades with each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
