Is located on the development side (arrow A side).

  Therefore, since the end 12A on the developing side of the screen 12 can be made even closer to the upper edge portion 102A of the rear window glass 102, the light shielding property to the rear window glass 102 can be further improved.

  Furthermore, according to this light-shielding device 10, since the 2nd connection arm part 44 of the connection part 40 is formed longer than the 1st connection arm part 42 (L1> L2), the dimension of the width direction of the light-shielding device 10 12A can be made closer to the upper edge portion 102 </ b> A of the rear window glass 102 while suppressing the above-mentioned.

  Moreover, according to the light shielding device 10, when the guide member 20 is rotated to the retracted position in a state where the moving member 18 is positioned on the proximal end side of the guide member 20, as shown in FIG. The first connecting arm portion 42 of the connecting portion 40 extends in the developing direction of the screen 12 on the developing side (arrow A side) of the screen 12 relative to the second connecting arm portion 44, whereby the moving member 18 is moved from the screen support member 16. Is also located on the unfolding side of the screen 12.

  Therefore, it can suppress that the connection part 40 prevents rotation to the storing position of the guide member 20 (suppression that the guide member 20 interferes with the screen support member 16). As a result, the guide member 20 is arranged in parallel with the screen support member 16 on the development side (arrow A side) of the screen 12 with respect to the screen support member 16 (the guide member 20 is positioned at the storage position), and the light shielding device 10 is compact. Therefore, for example, workability when the light shielding device 10 is mounted on a vehicle can be improved.

  Further, as shown in FIG. 8, the light shielding device 10 is mounted on the vehicle so that the screen 12 shields the rear window glass 102 from the lower side in the vertical direction. Since the screen 12 can be supported by the connecting portion 40 from the lower side in the vertical direction together with the member 16, the durability of the connecting portion 40 can be ensured.

  According to the light shielding device 10, the end 12 </ b> A on the development side of the screen 12 can be brought closer to the upper edge portion 102 </ b> A (window edge portion) of the rear window glass 102, so that the light shielding property to the rear window glass 102 can be obtained. In other words, it can also be understood that the length of the guide member 20 is sufficient.

  Next, a modification of one embodiment of the present invention will be described.

  In the said embodiment, although the light-shielding apparatus 10 was installed with respect to the rear window glass 102, you may install with respect to a front window glass or a side window glass. Moreover, the light-shielding device 10 is not limited to the configuration installed on the window glass of the vehicle, and may be installed on various window glasses.

  Moreover, in the said embodiment, although the connection part 40 was integrally formed in the moving member 18, it may be comprised separately from the moving member 18, and may be fixed to the moving member 18 integrally.

  In the above embodiment, as shown in FIG. 6, when the moving member 18 is positioned at the movement limit on the distal end side of the guide member 20, a part of the screen support member 16 is placed between the guide member 20 and the screen 12. Although overlapped in the unfolding direction, the screen support member 16 may be positioned completely on the unfolding side (arrow A side) of the screen 12 relative to the distal end portion 20A of the guide member 20.

  If comprised in this way, the edge part 12A of the expansion | deployment side of the screen 12 can be made to approach the upper edge part 102A of the rear window glass 102 more closely.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and various modifications other than the above can be implemented without departing from the spirit of the present invention. Of course.
