That is, the other end side of the first drawer plate constituting part 72A is arranged inside the U-shaped inner side on the one end part side in the second drawer plate constituting part 72B, and the first drawer plate constituting part 72A and the second drawer plate are arranged. The component 72B is rotatable about the shaft 78.

  A long hole 80 extending in the longitudinal direction of the second drawer plate constituting portion 72B is formed through the both side wall portions 172B of the other end portion (right end portion in the drawing) of the second draw plate constituting portion 72B. In the long hole 80, both end portions of the shaft portion 81 of the third drawer plate constituting portion 72C are movably disposed. One end portion (left end portion in the drawing) of the third drawer plate constituting portion 72C has a U shape with the second drawer plate constituting portion 72B side opened in a plan view, and the shaft portion 81 is the third drawer. It extends between the U-shaped side wall portions 172C facing each other in the plate constituting portion 72C and to the side of the U-shaped side wall portion 172C, and the axial direction is the shaft portions 76 and 78 (in the first drawer plate constituting portion 72A). This is the same as the axial direction in FIG.

  That is, one end portion (left end portion in the figure) of the third drawer plate constituting portion 72C is placed inside the U-shape on the other end portion (right end portion in the drawing) side in the second drawing plate constituting portion 72B. The third drawer plate constituting part 72C is movable relative to the second drawer plate constituting part 72B in the extending direction of the long hole 80, and the second drawer plate constituting part 72B and the third The drawer plate constituting portion 72 </ b> C is rotatable around the shaft portion 81. Here, by allowing the third drawer plate constituting portion 72C to move relative to the second drawer plate constituting portion 72B in the extending direction of the long hole 80, the draw plate portion 72 is adapted according to the unfolded state of the sun visor body 20. It is designed to adjust the overall length.

  Inside the U-shaped inner side of the second drawer plate constituting portion 72B, a tension coil spring 82 that functions as an urging means is disposed along the longitudinal direction of the second drawer plate constituting portion 72B. One end portion of the tension coil spring 82 is locked to the intermediate portion of the shaft portion 78 of the first drawer plate constituting portion 72A, and the other end portion of the tension coil spring 82 is secured to the shaft portion 81 of the third drawer plate constituting portion 72C. It is latched in the middle part. Thereby, the tension coil spring 82 is biased in a direction in which the first drawer plate constituting portion 72A and the third drawer plate constituting portion 72C are brought close to each other. Here, since the shaft portion 81 of the third drawer plate constituting portion 72C is movable along the long hole 80 of the second draw plate constituting portion 72B, a predetermined state (in this embodiment, FIG. ), The third drawer plate constituting portion 72C moves in a direction approaching the first drawer plate constituting portion 72A.

  As shown in FIG. 21, a gripping portion 83 that protrudes downward is formed at the center in the longitudinal direction of the second drawer plate constituting portion 72 </ b> B. The gripping portion 83 is used when the sun visor body 20 is opened and closed. And is provided with a finger hook portion 83A. The second drawer plate constituting portion 72B is formed with a pin 84 protruding from the U-shaped side wall portions 172B at right angles to the outer surface of the side wall portion 172B. In the retracted state of the sun visor main body 20, the pin 84 presses the wall portion 67 of the storage portion 66, thereby holding the sun visor main body 20 and the drawer plate portion 72 in the storage position. That is, in this embodiment, the pin 84 and the wall part 67 comprise a holding member, and hold | maintain the sun visor main body 20 to the upper part of the window frame part 12 (refer FIG. 19) in the folded state.

  Further, as shown in FIG. 20A, in the retracted state of the sun visor body 20, the first to third drawer plate constituting portions 72A to 72C are arranged to face the respective flat portions 68X. In other words, the drawer plate part 72 is bent along the plane part 68X (see FIG. 21) according to the shape of the storage part 66.

  According to the above configuration, the sun visor main body 20 is divided into a plurality (three in the present embodiment) corresponding to the straight line portions 68 in the storage portion 66, and each upper portion of the divided sun visor main body 20 is a flat portion 68X. Therefore, each of the divided sun visor main bodies 20 is stored in the storage portion 66 along the plane portion 68X by folding, and the pin 84 (see FIG. 20B) moves through the wall portion 67 of the storage portion 66. It is held by pressing from the inside. For this reason, the sun visor body 20 can be stored without being bent. Therefore, plastic deformation (permanent deformation) hardly occurs even if the sun visor main body 20 is not constituted by a material that does not bend and deform (flexible material). Further, the structure is simpler than the structure in which the so-called bellows-like sun visor body 20 is fixed to the curved window frame.

  Further, when the sun visor main body 20 is deployed, the gripping portion 83 in the pullout plate portion 72 is gripped and pulled downward, so that the bent pullout plate portion 72 is linear as shown in FIG. The separated sun visor body 20 (first sun visor body 20A, second sun visor body 20B, third sun visor body 20C) is pulled out in an integrated state. Thereafter, the pin 74 moves along the guide groove 65, so that the sun visor body 20 reaches the unfolded state shown in FIG.

  Here, since the drawer plate part 72 which connects the divided | segmented sun visor main bodies 20 is attached to the lower part of the sun visor main body 20, the divided | segmented sun visor main body 20 is moved by moving the drawer plate part 72 up and down. It can be stored and deployed in bulk (simultaneously). Therefore, light can be easily shielded with one action. Further, since the sun visor body 20 can be relatively moved in the direction (arrow X direction) intersecting the deployment direction with respect to the drawer plate portion 72 during deployment, the sun visor body 20 can be deployed without wrinkles. . Furthermore, since each sun visor main body 20 has an upper end portion fixed to the flat portion 68X (see FIG. 21) and a lower end portion fixed to the drawer plate portion 72 (with a slidable structure), the sun visor main body 20 is less likely to flutter.

  Thus, with a simple configuration, the sun visor body 20 can be shaped to fit the window frame portion 12 (see FIGS. 18 and 19) (auxiliary frame portion 62) both when stored and unfolded. By deploying the sun visor body 20 stored in a space-saving space (storage portion 66) along 12 (auxiliary frame portion 62), a large light shielding range can be secured.

  In the third embodiment, the surface portion including the straight portion 68 is the flat portion 68X, and it is most preferable to adopt such a configuration. However, the surface portion including the straight portion 68 is, for example, in a vehicle side view. Other shapes such as a linear shape and a zigzag shape when viewed from the front of the vehicle may be used.

In the third embodiment, the auxiliary frame portion 62 is fixedly disposed on the upper portion of the window frame portion 12 and the auxiliary frame portion 62 constitutes a part of the window frame portion 12. May be integrally formed as a part of the window frame portion 12.
