Description of the Related Art As a sun visor for vehicles used in automobiles and the like, polyurethane foam or the like is attached to the surface of a core material in which a frame formed of metal wires or the like is sandwiched between corrugated cardboard or a wooden board and fixed with tape or the like. A structure in which a buffer sheet material made of (1) is adhered and then covered with an exterior material such as a vinyl chloride sheet has been used. However, this type of sun visor has a complicated manufacturing process,
Since the use of corrugated cardboard causes problems such as a decrease in strength due to moisture absorption of corrugated cardboard, in recent years, a frame made of metal wires or the like has been embedded in a synthetic resin foam body to form an integrally formed core material. A material covered structure is used.

On the other hand, in recent years, a sun visor for vehicles, which is provided with an additional function by attaching a mirror, a lamp or the like, is also used. For example, in Japanese Patent Laid-Open No. 144221/1990, a synthetic resin foam is provided. There is disclosed a sun visor in which a mirror or the like is embedded and attached in the recess.

When a mirror or the like is attached to a sun visor, a method of accommodating the mirror or the like in a case body having an opening / closing lid and embedding and fixing the case body in a recess is generally adopted in high-class vehicles. As a method of fixing the case body in this case, a bracket material provided with screw holes or the like is attached to the frame forming the core material by welding or the like, and the case body is fixed to the bracket material with screws. ,
It is known that the case body is embedded in the recess and then the exterior material of the sun visor is fixed by directly adhering to the periphery of the case body.

[0005]

However, although the former structure in which the bracket material is welded to the frame is excellent in the attachment strength of the case body, the time and labor required for welding the bracket material is high and the weight is high. There was a problem of getting bigger. On the other hand, the latter structure, in which the exterior material of the sun visor is directly fixed to the case body by welding, adhesive, etc., has a simple structure and is excellent in manufacturing cost, but the fixing strength of the case body is the material strength of the exterior material. Since it depends only on the case, it can be installed with a slide type opening / closing lid or a case body with no opening / closing lid, but a case body with a structure in which the opening / closing lid is opened and closed by a hinge etc. In this case, when the opening / closing lid is opened and closed, an unreasonable load is applied to the exterior material, the exterior material is stretched or damaged, and the case body is loosely fixed.

The present invention solves the above-mentioned problems of the prior art, and even a case body having a rotary opening / closing lid can be securely fixed, and the manufacturing process is complicated and the cost is high. The purpose is to provide a light, excellent vehicle sun visor.
