して形くずれが起きやすい上、表面を覆っているビニル
シートに皺がよって美観上も好ましくないという問題点
があった。Conventionally, wooden or synthetic resin boards or polyurethane foam sheets have been used as sun visors.
However, a wooden or synthetic resin plate is hard, and if the head collides with it, there is a risk of injury, while a polyurethane foam sheet is too soft and easily sagged, and easily deteriorates and loses its shape. There is a problem in that the vinyl sheet covering the surface is wrinkled, which is not preferable in aesthetic appearance.
そこでこれらの問題点を解決するため、スチレン系樹

した。For this reason, the present inventors have conducted various studies on various foams. As a result, a polyethylene-based resin foam molded article, particularly a crosslinked polyethylene having a skin portion thickness that is three times or more larger than the cell thickness inside the foamed particles. The inventors have found that the above problems can be solved at once by using foaming, and have reached the present invention.

体である。The polyethylene resin foam molded article used in the present invention has a density of 0.925 to 0.940 g / cm 2 described in JP-B-63-11975.
After the polyethylene resin particles are cross-linked and then impregnated with a foaming agent, the foaming agent on the surface of the particles is volatilized preferentially, and then the entire foaming treatment is performed to obtain a film thickness of the cell structure inside. Foamed particles having a skin portion film thickness about three times or more larger than the foamed particles are formed, and then the foamed particles are filled in a mold after an expansion ability imparting treatment, and heated and expanded to perform fusion between the foamed particles. The obtained molded article is subjected to an aging treatment at a temperature of 60 ° C. or more for at least 6 hours, and a polyethylene foam molded article having substantially no interparticle gap on the surface, specifically, MEF manufactured by Asahi Chemical Industry Co., Ltd. (Registered trademark).
次に本発明のサンバイザーを製造する方法を説明す

る。First, a core made by bending a metal wire, for example, a copper-plated rope, is set in a mold, and then the mold is clamped. This is filled with a predetermined amount of raw material PE beads, heated, and foamed. Next, after cooling this, the mold is opened and the molded sun visor body is taken out. After that, this is covered with a facing material and finished. In addition, a PVC leather, a sheet, a cloth, a laminate thereof, or the like is used as the surface material.
