<Embodiment 1>
Embodiment 1 of the present invention will be described with reference to the drawings of FIGS. As shown in FIG. 2, the sunshade device 10 in the present embodiment has a front window 50 that extends to the front side of the ceiling portion 52, and the front window 50 forms a part of the front side of the ceiling portion 52. Applies to That is, the front window 50 extends to above the driver's seat (passenger seat) and is continuous with the ceiling portion 52. This sunshade device 10 is installed in order to block the light inserted from the front window 50.

  As shown in FIG. 1, the sunshade device 10 is disposed at the rear of the movable header 11 (an example of the “front shade member” of the present invention) 11 that is disposed along the vehicle interior side upper portion of the front window 50. Board shade (an example of the “rear shade member” of the present invention) 12 and the like. A ceiling interior material 13 is disposed behind the front window 50. The ceiling interior material 13 is attached to the lower surface side of the roof panel constituting the ceiling portion 52. On the roof side members 22a and 22b constituting both sides in the vehicle width direction of the ceiling portion 52, guide rails 20a and 20b having a substantially gate-shaped cross section (an example of the “guide member” of the present invention) are attached, respectively.

  Guide ribs 12a and 12b are provided at both ends of the board shade 12 in the vehicle width direction. The guide ribs 12a and 12b are fitted inside the two guide rails 20a and 20b, respectively. Thereby, the board shade 12 is guided in the vehicle front-rear direction along the guide rails 20a, 20b. The board shade 12 includes a driving unit (not shown) and can be driven independently of the movable header 11. For this reason, the board shade 12 has a light blocking position (a position of the board shade 12 in FIG. 3) for blocking light inserted into the indoor space and a lighting position (a position of the board shade 12 in FIG. 2) for collecting the light into the indoor space. It is possible to move in the vehicle longitudinal direction.

  Guide protrusions 11a and 11b are provided at both ends of the movable header 11 in the vehicle width direction. The guide protrusions 11a and 11b are fitted inside the two guide rails 20a and 20b, respectively. Thereby, the movable header 11 is guided in the vehicle front-rear direction along the guide rails 20a and 20b.

  The movable header 11 includes a holding member (an example of the “driving mechanism” of the present invention) 14 that is held in a connected state with the board shade 12. Thereby, although the movable header 11 cannot move independently, it is movable to the vehicle front-back direction with the movement of the board shade 12 by being connected with the board shade 12 by the holding member 14. In this connected state, the movable header 11 reaches the rear position (position of the movable header 11 in FIG. 2) when the board shade 12 reaches the daylighting position, and the front position (movable header in FIG. 3) when the board shade 12 reaches the light shielding position. 11 position).

  The holding member 14 is disengaged from the movable header 11 at the front position and can be engaged with the guide rails 20a and 20b. For this reason, as shown in FIG. 4, the board shade 12 can move to the daylighting position while leaving the movable header 11 at the front position. At this time, since the holding member 14 is engaged with the guide rails 20a and 20b, the movable header 11 at the front position is restricted from freely moving in the vehicle front-rear direction.

  A plate-like sun visor 40 that can be rotated between a light shielding position and a storage position is attached to a surface of the movable header 11 on the vehicle interior side. One sun visor 40 is attached to each of the upper position of the driver seat and the upper position of the passenger seat. By moving the movable header 11 to the front position, the occupant seated in the driver's seat and the passenger seat can use the sun visor 40.
