To provide a sun visor capable of not only avoiding cracks and damage of an outside cylindrical member but also securing sufficient safety for a crew.SOLUTION: A sun visor includes a sun visor body for blocking light, and a support arm 4 for supporting the sun visor body. The support arm is constituted by an inside cylindrical member 26 having a hollow space 34 and an outside cylindrical member 28 covering the inside cylindrical member 26, the outside cylindrical member 28 is formed of a hard resin material, and the inside cylindrical member 26 is formed of a resin material or a rubber material softer than the outside cylindrical member 28. Preferably, the inside cylindrical member 26 is formed of a thermoplastic elastomer, or the like, and the outside cylindrical member 28 is formed of a nylon resin or a polypropylene resin, or the like. Preferably, the thermoplastic elastomer is mixed with a metal or glass filler for molding.SELECTED DRAWING: Figure 2 【課題】外側筒状部材の亀裂、破損を回避することができるとともに、乗員に対しても充分な安全性を確保することができるサンバイザを提供すること。【解決手段】光を遮るためのサンバイザ本体と、サンバイザ本体を支持するための支持アーム４とを備えたサンバイザ。支持アームは中空空間３４を有する内側筒状部材２６と、内側筒状部材２６を覆う外側筒状部材２８とから構成され、外側筒状部材２８は硬質樹脂材料から形成され、内側筒状部材２６は、外側筒状部材２８よりも柔らかい樹脂材料又はゴム材料から形成される。この内側筒状部材２６は、熱可塑性エラストマなどから形成し、外側筒状部材２８はナイロン樹脂又はポリプロピレン樹脂などから形成するのが好ましい。また、熱可塑性エラストマには金属製又はガラス製の成形用フィラーを混入するのが好ましい。【選択図】図２
