When the knob 24k is turned and the screw is tightened in this state, the knob 24k and the clamp 24c press the base 24a and the support 24b in the direction approaching each other, so that the support 24b is fixed on the base 24a. Therefore, the clamping part 24 is fixed in a state where the sun visor body 15 is clamped. Thereby, the auxiliary sun visor 22 is attached to the sun visor body 15.

  In the vehicle sun visor 10 of the above-described modified example, the auxiliary visor 22 is attached to the sun visor main body 15 of a general vehicle sun visor by holding the sun visor main body by the holding portion 24 without being easily damaged. In addition, since the auxiliary sun visor 22 is attached to the sun visor body via the hinge mechanism 25 in the vehicle sun visor 10, the auxiliary sun visor 22 remains in the state in which the sun visor main body 15 is stored in the ceiling portion 12 (see FIG. 1) of the vehicle. Only tilt can be used. Further, since the auxiliary sun visor 22 is disposed in the vehicle sun visor 10 so as to be able to enter and exit from the holding portion 24 by the hinge mechanism 25 in the holding direction, the auxiliary sun visor 22 is pulled down and used from the state where the sun visor body 15 is tilted. You can also

  Therefore, the mounting plate 23 is the same as the sun shield 17 so that the sun visor main body 15 can be tilted when it is desired to completely shield light, and the mounting plate 23 can be tilted when it is desired to reduce glare. It is desirable to form a material having a sunglasses function.

  Therefore, according to the present modification, the use of the auxiliary sun visor 22 does not damage a general vehicle sun visor, and the usage is selected according to the situation to reduce the glare of sunlight that hinders the sight of the occupant. Can do.

  The sandwiching portion 24 may be any member that sandwiches the sun visor body 15 and fixes the mounting plate 23 to the sun visor body 15 and can be directly attached to the mounting board 23 without using the hinge mechanism 25. It is not limited to examples.

  Next, Example 3 will be described. The third embodiment is an example in which the sunshield 17 of the first embodiment is controlled by an electric mechanism to be taken in and out. Each direction is the same as in the first embodiment.

  Since the basic configuration of the present embodiment is the same as that of the first embodiment, detailed description thereof is omitted.

  In the first embodiment, two guides 16 are provided, and the sunshield 17 is fitted in the recesses 15c of the two guides 16. However, in this embodiment, as shown in FIG. A short guide 16b having a shorter length is provided, and a sunshield 17 is fitted to both the guides 16 and 16b. The guide 16 is not provided with a stopper member 16a.

  The sun shield 17 is not formed with the convex member 17a or the protrusion 17b as in the first embodiment. A fixing portion 17d that protrudes outward in the vehicle width direction is formed above the side end of the sunshield 17 fitted to the short guide 16b.

  A motor 26 as an electric mechanism is provided above the short guide 16b (upper end portion of the sun visor body 15). The motor 26 has the same configuration as a small motor for moving a well-known vehicle antenna or the like, and includes a rod 26a and a motor body 26b. The motor body 26b is controlled by a circuit (not shown) to expand and contract the rod 26a. The tip of the rod 26 a is fixed to the fixing portion 17 d of the sun shield 17.

  Since the range of the sun shield 17 can be defined by the rod 26a of the motor 26, the stopper member 16a and the protrusion 17b (see FIG. 2) as the restricting portions are not provided, but may be provided from a safety aspect.

  According to the present embodiment, the occupant can put in and out the sun shield 17 by operating the motor 26, and can reduce the glare of sunlight that hinders the sight of the occupant. In this way, when the sunshield 17 is inserted and removed from the sun visor body 15 by electric power, the dazzling of sunlight that hinders the field of view overlaps with the direction of the field of view of the occupant while reducing the safety of the occupant during driving. As a result, the occupant can sufficiently secure the field of view necessary for driving.

  Although the motor 26 is used in this embodiment, for example, wires are connected from both ends to protruding portions of the sunshield that are instructed so that both ends can be pulled out with guides and fitted to the guides. This wire is disposed along the guide, passes through the upper and lower ends of the guide, and is connected to the motor. Since the wire is driven by the motor and the protruding portion of the sunshield can be moved along the guide, the sunshield can be controlled by the motor. The electric mechanism is limited to the present embodiment as long as it can control the insertion and removal of the sunshield 17 from the sun visor body 15 by an electric force, such as a mechanism for moving the window of the power window using such a wire. It is not something.

  In the present embodiment, the sun shield 17 of the first embodiment is electrically controlled to be taken in and out, but the auxiliary sun visor of the vehicle sun visor 10 of the second embodiment is provided by providing a similar mechanism to the auxiliary sun visor 22 of the second embodiment. The sunshield 17 provided at 22 can be controlled by electric drive. In this case, the mounting plate 23 must be formed in such a size that can be provided on the mounting plate 23 so that the insertion and removal of the sunshield 17 from the sun visor body 15 can be controlled by the above-described electric motor.

  In each of the above-described embodiments, the guide 16 has a shape in which the two side ends of the sunshield 17 are movably supported by the two guides 16 (or 16b). However, the direction in which the sunshield 17 is pulled out is defined. Further, any shape may be used as long as both ends of the sunshield 17 are movably supported. For example, a telescopic rod such as the rod 26 a of the third embodiment can be provided in place of the guide 16. In this case, the sunshield 17 does not need to be provided with a restriction portion because the drawing range is determined by the rod, but it is difficult to draw the sunshield 17 by its own weight. For this reason, in order to facilitate the drawing, it is desirable to provide a recess as a handle for pulling out at the lower end of the sun shield 17 and to perform a process such as providing a groove in the sun visor body 15 to make it easy to grip the recess. . Two guides 16 may be integrally formed. The guide 15 can be formed by cutting the recess 15 c of the sun visor body 15. In addition, the guide 16 can be directly attached to the surface 15 a of the sun visor body 15 without forming the stepped portion 15 b and the recessed portion 15 c of the sun visor body 15.

  The stopper member 16 a of the guide 16 and the convex member 17 a of the sun shield 17 are provided as a restricting portion that restricts the movement range of the sun shield 17 drawn along the guide 16. For this reason, the restricting portion is not limited to the position and shape shown in this embodiment, and the position where the sun shield 17 is pulled out from the sun visor body 15 and stopped by the restricting portion is viewed from the occupant. What is necessary is just to have a function in which the incident direction of sunlight close to the horizontal direction and the sunshield 17 overlap each other.

  In each of the embodiments described above, the push latch mechanism is configured such that the projection 17b is held by the receiving portion 19, but a ferromagnetic material such as iron is used instead of the projection 17b at the center of the upper end of the sunshield 17. The receiving part 19 may be provided with a receiving part having a lock latch mechanism using the attractive force of the magnet. Further, the receiving portion 19 may be formed on the sun shield 17 and the protruding portion 17 b may be formed on the sun visor body 15.

  From the standpoint of safety, the protective material 20 is attached to the lower end of the sunshield 17 or formed so that the lower end of the sunshield 17 is covered by the protective material 20 that covers the sun visor body 15 when the sunshield 17 is stored. Is desirable.

  A depression as a handle may be provided in the lower part of the sun shield 17. If there is such a depression, the operation when pulling out the sunshield 17 becomes easier. You may give the thickness like an edge to the peripheral part of the both ends of a sunshield 17, and a lower end part. In this way, the strength of the sunshield 17 can be increased.

  For example, a sun visor having a length of 11 cm, a width of 28 cm, a thickness of 2 mm, and an edge portion of 3 mm was formed as the sun shield 17, and a sun visor provided with a regulating portion at the position shown in Example 1 was manufactured. When the sun visor was actually attached to the automobile, it could be easily stored in the sun visor body 15 and the sunlight incident upon overlapping with the sight direction of the occupant could be easily reduced.
