By rotating the sun visor 10 from the front position to the side position by a predetermined angle, the claw parts 2
0 rides on the upper surface side of the intermediate stay 18 and is disengaged from the groove portion 29. That is, when the starting end of the taper 20a of the claw portion 20 is located at the front position, coinciding with the longitudinal axis Ls of the sun visor 10 (see FIG. 7).
For example, when the sun visor 10 is rotated clockwise by an angle α, the engagement between the pawl 20 and the groove 29 is released, and the sun visor 10 is further rotated clockwise by an angle β. By doing so, the sun visor 10 can be set to the side position.

In the above configuration, when the sun visor 10 is located approximately along the windshield 8 as shown by the solid line in FIGS. 1 and 3, the movable stay 19 It is in a state of being moved toward the intermediate stay 18 side against the biasing force, and at this time, the claw portion 20 is fitted into the groove portion 29. Further, the disk 26 of the extension rod 25 of the movable stay 19 is connected to the claw portion 20.
By being locked at , the movable stay 19 (that is, the light shielding plate 11) is locked at a predetermined position in the longitudinal direction of the stay 12 (see FIG. 5). From this state, the sun visor 10 is moved backward at a predetermined angle (α) in plan view using the support part of the support fitting 9 as a fulcrum.
When the above-mentioned rotation is made, the engagement between the claw portion 20 and the groove portion 29 is released, and as a result, the movable stay 1 is
9 is released from the locked state, and as shown in FIG. 6, the movable stay 19 (that is, the light shielding plate 11) is moved rearward along the longitudinal direction of the stay 12 by the biasing force of the second spring 28. It looks like this.

That is, when the sun visor 10 is rotated and set in a position along the door glass 7, the light shielding plate 11 moves backward by a predetermined amount due to this rotation, so that the upper front side of the door glass 7 This prevents the visibility of the rearview mirror 5 from being obstructed. Moreover, in this case, simply by rotating the sun visor 10 to the side position, the above-mentioned moving operation of the light shielding plate when set to the side position is automatically performed, so that operability is good.

In the above embodiment (hereinafter referred to as the first embodiment), the stay 12 having a three-part structure was supported by the support fitting 9, but the support stay and the support fitting were integrated into one body. By forming the stay, the stay can be made into a two-part structure, and the structure can be simplified. That is, FIG.
And as shown in FIG. 11, the stay 72 is connected to the intermediate stay 73.
and a movable stay 74, and the intermediate stay 73 is formed into a substantially L-shape, and the upper part of the short side thereof is rotatably supported by the lower end side of the support fitting 69. An engaging member 81 and a first spring 82, which operate in the same manner as in the first embodiment, are housed at the lower end of the support fitting 69. Further, the movable stay 74 is formed into a pipe shape, and the long side of the intermediate stay 73 is inserted into the interior of the movable stay 74.

By rotating the sun visor 70 toward the side position, the engagement between the claw portion 80 of the engaging member 81 and the groove portion 89 of the intermediate stay 73 is released, and the movable stay 74 is moved by the intermediate stay 73. The locked state is released,
The light shielding plate 71 is allowed to slide until the distal end disk 76 of the rod member 75 comes into contact with the stopper 77 (see the broken line arrow in FIG. 11). still,
The light shielding plate 71 is formed into a flat shape by a pad 71c and a skin 71b covering the outer surface thereof, and a core bar 71a for shape retention is disposed inside the light shielding plate 71. Further, in the case of this embodiment, the locking bar on the side opposite to the support portion is formed by extending the movable stay 74.

Next, a second embodiment of the present invention will be described. In the following explanation, the same parts as in the first embodiment are given the same reference numerals, and further explanation will be omitted. As shown in FIG. 12, in the sun visor 30 according to this embodiment, a light shielding plate 31 is supported by a one-piece stay 32 that is approximately L-shaped. As shown in FIGS. 14 and 15, the stay 32 has an L-shaped long side formed in the shape of a hollow pipe, and near its tip, as shown in detail in FIG. A spring 34 (first spring) that biases the knob 33 outward is housed, and a protrusion 33a of the operation knob 33 is disposed on the side wall of the spring 34 (first spring).
A hole 32a is provided into which the holder is inserted. On the other hand, a guide tube 36 is embedded inside the upper side of the light shielding plate 31 to cover the outer circumference of the stay 32 and guide the stay 32 in a longitudinally slidable manner, and the bottom of the guide tube 36 and the stay 32 are closed. The stay 32
A second spring 37 is compressed to urge the support part 9 toward the support part 9. Further, the guide tube 36 and the side wall portion of the sun visor skin portion 30a covering the outside thereof have first and second protrusions into which the projections 33a of the operation knob 33 are fitted at two predetermined locations in the longitudinal direction. Side hole 3

Then, by pushing in the operation knob 33 and releasing the engagement between the protrusion 33a of the knob 33 and the horizontal holes 38 and 39, the stay 32 and the guide tube 36 are slid relative to each other in the longitudinal direction. It is now possible to move it.

The sun visor 30 is normally used with the protrusion 33a of the operation knob 33 inserted into the first horizontal hole 38, and set at the front position approximately along the top of the windshield 8. (See Figure 14). When switching from this front position to the side position, the sun visor 30 is rotated and set to the side position, and then,
Push in the operation knob 33 to remove the protrusion 33 of the knob 33.
a and the first horizontal hole 38 is released. At this time, the light shielding plate 31 is slid rearward with respect to the stay 32 by the biasing force of the spring 37 to a position where the projection 33a engages with the second horizontal hole 39 (Fig. 15 reference). As a result, the sun visor 3
Even when 0 is set to the side position, visibility of the rearview mirror 5 can be ensured by leaving the upper front side of the door glass 7 open.

It should be noted that the operation knob 33 is
a may be provided so as to protrude not from the side surface of the light shielding plate 31 but from the upper surface side. Furthermore, as shown in FIG. 16, by forming the opposite side of the protrusion 43a of the operation knob 43 into a tapered shape, when the light shielding plate 41 is slid toward the support portion with respect to the stay 42 (see FIG. 16), the protrusion 43a can be configured to be automatically pushed downward from the horizontal hole 49 with this sliding movement.

Next, a third embodiment of the present invention will be described. As shown in FIGS. 17 to 19, in this embodiment, the stay 52 of the sun visor 50 is formed into a substantially L-shape, and the upper end of its short side is rotatably supported by the support fitting 9. 57, a third stay 59 that supports the light shielding plate 51 at one end, and a second stay 5 that connects both stays 57 and 59.
The first stay 57 is divided into three parts.
and the second stay 58 are connected by a first joint member 55, and the second stay 58 and the third stay 59 are connected by a second joint member 56, respectively. The first and second joint members 55 and 56 both support the ends of the shaft members to be connected while applying a moderate frictional force, and also enable the shaft members to rotate at least in a horizontal plane. It is a ball-type supporting device, and it is shown in Figure 1.
As shown by the solid line at 9, the first joint member 55
, the rotation fulcrum Cs of the support part of the support fitting 9 and the light shielding plate 51
By locating the first stay 57 and the second stay 58 rearward, the first stay 57 and the second stay 58 are folded into a V-shape in a plan view.
The light shielding plate 51 can be set at a front position substantially along the windshield 8 with a relatively short distance from the rotation fulcrum Cs (see FIG. 17).

When switching the light shielding plate 51 from the front position to the side position, the first stay 57 is rotated rearward in plan view, and the second stay 58 is rotated, as shown by the broken line in FIG. The first joint member 55 is rotated in a horizontal plane using the first joint member 55 as a fulcrum.
By extending it in a straight line with the stay 57, the light shielding plate 5
1 can be set at a side position substantially along the side glass 7 while maintaining the maximum distance from the rotation fulcrum Cs (see FIG. 18). That is, even when the sun visor 50 is set to the side position, the upper front side of the door glass 7 is left open and the visibility of the rearview mirror 5 can be sufficiently ensured.

Furthermore, by using joint members 55 and 56 of a type that rotatably supports the connecting member not only in the horizontal plane but also in the vertical plane, the sun visor 50 can be mounted on its supporting portion as a fulcrum. When rotating in the front-rear direction in a plan view, it can be rotated not only in the horizontal plane but also in a vertically slanted state.
Improves rotational operability. Moreover, when folding the first stay 57 and the second stay 58 at the front position, they can also be folded downward, improving layout properties.
