As shown in FIG. 2, the support shaft 4 is divided by a pair of divided bodies 4a and 4b formed in a semi-cylindrical shape. The pair of divided bodies 4a and 4b are injection-molded with a thermoplastic synthetic resin, and welding concave portions 11 and welding convex portions 12 are alternately formed on a surface where the pair of divided bodies 4a and 4b are joined. ing. Further, a semicircular step portion 13 for forming a holding groove 14 for holding the support shaft holding portion 6 is provided at both ends of each of the pair of divided bodies 4a and 4b.

The sun visor body 2 is covered with a skin 8. The skin 8 is formed of a sheet material such as a woven fabric, a nonwoven fabric, or a synthetic resin sheet, and is formed into a bag shape corresponding to the shape of the sun visor body 2 by ultrasonic welding, high frequency welding, or the like. When the skin 8 is formed by ultrasonic welding or high-frequency welding, a sheet material larger than the vertical and horizontal dimensions of the sun visor body 2 is covered from both front and back surfaces, and the ultrasonic or high-frequency cutting along the peripheral edge of the sun visor body 2 is performed. By performing the welding at the same time, the sheet materials are joined and formed into a bag shape corresponding to the shape of the sun visor body 2. In the present embodiment, the skin 8 is formed by ultrasonic welding.

FIG. 4 is a sectional view taken along the line AA of FIG. The skin 8 is cut off along the periphery of the support shaft holding portion 6 and is ultrasonically welded at the welding portion 9 from both the front and back surfaces of the sun visor body 2. Here, the support shaft holding unit 6
Are formed in the support shaft installation portion 7 in a concave shape, so that the skin 8 covering the sun visor body 2 and the support shaft holding portion 6
A gap 10 which is a space formed due to the inability to adhere to each other is formed therebetween. At the ends of the divided bodies 4a and 4b, the support shaft holding portion 6 is sandwiched from both the front and back surfaces, and the support shaft 4 is installed on the support shaft installation portion 7 by joining them. That is, the support shaft 4 is installed with respect to the sun visor main body 2. Split body 4a, 4b
When welding is performed, the welding concave portions 11 and the welding convex portions 12 alternately formed on the joining surfaces engage with each other, and are joined by ultrasonic welding.

FIG. 5 is a sectional view taken along the line AA of FIG. 3, and shows a state in which the divided bodies 4a and 4b are joined and the support shaft 4 is installed on the support shaft installation portion 7. Since stepped portions 13 are provided at both ends of the two divided bodies 4a and 4b, holding grooves 14 are formed at both ends of the support shaft 4 to which they are joined. The support shaft 4 has the holding groove 1
The support shaft 4 is installed on the support shaft installation unit 7 with the support shaft holding unit 6 sandwiched between the support shaft installation unit 6 and the skin 8. here,
Before the support shaft 4 is installed on the support shaft installation portion 7, a gap 10 is formed between the skin 8 and the support shaft holding portion 6, but the holding groove 14 connects the skin 8 with the support shaft holding portion 6. The outer skin 8 is sandwiched between the support shaft holder 6 and the support shaft holding portion 6 by pressing and contacting with the support shaft holding portion 6. The skin 8a (see FIG. 4) that forms the gap 10 with the support shaft holding portion 6 and the skin 8b (see FIG. 5) after being pressed against the support shaft holding portion 6 by the holding groove 14. The latter (skin 8b) requires more length. Therefore, the skin 8 is preferably made of a material having elasticity (such as a synthetic resin) so that the skin 8 can be deformed when sandwiched between the support shaft holding portion 6 and the holding groove 14. In addition, a material in which the skin 8 does not have elasticity (a non-woven fabric or the like)
Even if it is constituted, if the length of the skin 8a forming the gap 10 in FIG. be able to. At this time, it is preferable that the skin 8a forming the gap 10 has a length necessary and sufficient to form the skin 8b after being sandwiched by the holding grooves 14 of the support shaft 4. To do so,
The length of the skin 8a is adjusted by separating the position of the welding portion 9 for applying the ultrasonic welding to the skin 8 from the peripheral edge of the support shaft holding portion 6 as appropriate, so that the length of the skin 8a has a necessary margin. Can be made.

Since the support shaft 4 sandwiches the support shaft holding portion 6 with the holding groove 14, the support shaft holding portion 6
Even if the sun visor body 2 is rotated around the support shaft 3 in a state where the sun visor body 2 is in contact with the front and back surfaces of the sun visor body 2 while being hooked on the support hook 5, It is fixed and does not rotate relatively. Therefore, the support shaft 4 and the skin 8 are not rubbed, and abnormal noise is not generated, and the skin 8 is not broken. Further, since the support shaft holding portion 6 is formed in a concave shape, when the support shaft 4 is installed on the support shaft installation portion 7, the end of the support shaft 4 fits into the concave portion. The end of the support shaft 4 is restricted from moving in a direction horizontal to the surface of the sun visor body 2 by the support shaft holding portion 6 formed in a concave shape with respect to the surface of the sun visor body 2. Thereby, it is possible to prevent the support shaft 4 from being displaced in the lateral direction from the support shaft holding portion 6 and coming off.

This means that the skin is adapted to the shape of the peripheral portion of the support shaft installation portion 7 (substantially square shape in the embodiment) as compared with the case where the skin 8 is covered after the support shaft 4 is installed on the sun visor body 2, for example. Since it is only necessary to melt the surface 8, the terminal treatment of the epidermis 8 does not require much work. On the other hand, when covering the sun visor main body 2 on which the support shaft 4 is already installed with the skin 8, the terminal treatment of the skin 8 must be performed according to the complicated shape of the portion where the support shaft 4 is installed. Must be troublesome. In addition, the sun visor 1 for a vehicle according to the present invention.
The support shaft mounting portion 7 formed on the sun visor body 2
Since the support shaft 4 can be directly installed on the sun visor main body 2, it is not necessary to incorporate the support core shaft body 106 and the like inside the sun visor main body 2 unlike the conventional vehicle sun visor.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the support shaft installation portion 7 is formed by cutting out the upper end portion of the sun visor body 2 into a substantially square shape, but is formed by cutting out the other shape (for example, a semicircular shape). You may. The example in which the support shaft is formed into a hollow shape by injection molding of a thermoplastic synthetic resin is shown, but the invention is not limited to this. The support shaft may be made of a material other than the thermoplastic synthetic resin, for example, metal, wood, or the like, or may be formed in a solid state. In addition, although the support shaft has been described as an example in which the cross-sectional shape is formed in a circular shape, other shapes such as a triangular or quadrangular shape are not limited. Furthermore, although the example in which the two divided bodies forming the support shaft are formed in a substantially symmetrical semi-cylindrical shape has been described, the two divided bodies having different shapes / sizes are joined to each other to form the support shaft. May be configured. The support axis does not necessarily have to be split into two,
It can also be constituted by a single part or two or more parts. For example, when the support shaft is composed of a single part (a single cylinder or the like), a clamping structure such as a groove or a clip is provided at both ends, and the support shaft holding portion is formed by the clamping structure. By sandwiching the support shaft with the skin, the support shaft can be installed at the support shaft installation portion.

Although the sun visor body is shown as being formed by injection molding of a thermoplastic synthetic resin, the present invention can be applied to a sun visor body formed by various other methods. For example, the present invention can be applied to a sun visor body manufactured by blow molding of a thermoplastic synthetic resin. Further, the material of the sun visor body is not limited to the thermoplastic synthetic resin, and may be made of various other materials. Although the example in which the support shaft holding portion is formed as a semi-elliptical concave portion has been described, the shape is not limited to such a shape. For example, as long as the position of the support shaft can be fixed when the support shaft is installed, such as a semicircular concave portion or a rectangular concave portion, the concave portion can be formed as a concave portion having various shapes.

[0021]

According to the present invention, a sun visor for a vehicle can be realized in which the support shaft is fixed to the sun visor body and does not relatively rotate when the sun visor body is rotated around the support shaft. Therefore, it is possible to prevent the support shaft and the skin from rubbing to generate abnormal noise, and to prevent the skin from breaking due to the friction with the support shaft.
