In FIG. 1, 11 is a car body, 12 is a passenger compartment of the car, 13 is a ceiling of the car body 11, and 14 is an L-shaped support shaft attached to the left end of the front end of the ceiling 13. As shown in FIG. 2, this support shaft 14 is formed in an L-shape by a vertical shaft portion 14a and a horizontal shaft portion 14, and the horizontal shaft portion 14b has a flat portion 14c as shown in FIG. is provided.

15 is a sun visor. This sun visor 15 consists of a core pad 16 (FIG. 4) and a frame-shaped iron wire 1 buried along the periphery of the pad 16.
7, a mounting bracket 18 that engages both ends of the iron wire 17 on one edge side of the pad 16, and a skin 19 made of PVC or the like that covers the surface of the pad 16. Furthermore, the mounting bracket 18 is integrally provided with a support shaft fitting portion 20 and a quick return spring 21.

The horizontal shaft portion 14b of the support shaft 14 is rotatably fitted into the support shaft fitting portion 20, and a frictional locking force is exerted between the horizontal shaft portion 14b and the support shaft fitting portion 20. It's working. This allows sun visor 15
One edge is rotatably supported by the horizontal shaft portion 14b. Further, the quick return spring 21 is composed of a pair of spring pieces 21a, 21a, and a flat portion 14c is disposed between the spring pieces 21a, 21b.

Here, if the surface of the sun visor 15 described above that faces the ceiling 13 in the horizontal direction 15 is the back surface 15a, a recess 22 is formed in the back surface 15a, and a vanity mirror is provided in the recess 22. 23 and a lighting bulb 24 are attached. A lid 25 is integrally hinged to one edge of the recess 22, that is, the other edge of the sun visor 15 via a thin hinge 25a. This lid 2
Reference numeral 5 indicates a core material 33 made of paper board or the like, and a pad 34 made of urethane or the like and covering the core material 25b.
and an outer skin 35 such as PVC. The lid 25 allows the recess 22 to be opened and closed. Furthermore, fasteners 26, 26 are attached to the free ends of the inner surface of the lid 25, and fasteners 27, 27 are attached to the other edge of the recess 22, and the fasteners 26, 26 are engaged with the fasteners 27, 27. It's starting to look like it's being done. Moreover, fan-shaped bellows light shielding members 28, 2 are provided on both sides of the inner surface of the lid 25.
