JP 2002-331040 A (3rd page, FIGS. 1 to 4)

  As shown in FIG. 16 described above, the pair of rectangular flat plate portions 2 and the first and second belt-like flat plate portions 3 and 4 have an annular shape obtained by, for example, being integrally formed by resin molding. The head mounting tool 1 formed as a flat plate-shaped product is formed into a flat plate shape so that the mold used for the molding can be easily created. In addition, the mold can be easily molded from the mold. Since it is easy to pull out, a situation in which the manufacturing cost increases is avoided. However, such a head mounting tool 1 has the first and second belt-like flat body portions 3 and 4 bent and mounted on the user's human head as shown in FIG.
