In the light guide 50, when light from the light source 30 enters from the light incident portion 51, the light reflected downward by the concavo-convex shape 54 exits downward from the lower surface (52). The concavo-convex shape 54 can be formed by a roughening process in which a blast material is sprayed after the light guide 50 is formed, a process in which a resin material is injected into a mold having a concavo-convex shape, and the concavo-convex shape is transferred.
FIG. 7C shows the back surface of the light guide 50 with the reflection plate 55 provided on the top surface. In the light guide 50, when light from the light source 30 enters from the light incident portion 51, the light reflected downward by the reflection plate 55 exits downward from the lower surface (52). As the reflection plate 55, a metal plate, a laminated plate in which a metal thin film is laminated on a resin plate such as a thermoplastic resin, or the like can be used. Of course, a film-like reflective film or the like may be used instead of the reflective plate 55.
In addition, in order to emit light from the lower surface serving as the side surface portion of the long light guide, a part or all of the combinations of the scatterer 53, the uneven shape 54, and the reflection plate 55 may be provided in the light guide.

  In the automobile 1 shown in FIG. 8, the light guide 50 is disposed closer to the rear seat 12 than the rear door 13 in a state where the cargo space L1 is closed in the front-rear direction (drawing direction D1). Here, the distance in the front-rear direction (D1) between the front surface 13b of the rear door 13 and the light guide 50 when the partition device main body 40 is attached to the deck side trim 20 is defined as d1 (d1> 0). Further, a front wall portion that forms the front side of the cargo space L1, that is, a distance in the front-rear direction (D1) between the back surface 12b of the sheet 12 and the light guide 50 is d2 (d2 ≧ 0). d2 = 0 means that the light guide 50 is in contact with the back surface 12b of the sheet. The position in the front-rear direction (D1) of the light guide 50 provided in the partition device main body 40 is preferably d2 <d1, more preferably d2 <d1 / 2, and further preferably d2 <d1 / 3. When the light guide 50 is arranged at such a position, the lower cargo space L3 is illuminated from the back as viewed from the rear door 13, so that it is large when loading / unloading the cargo with respect to the lower cargo space L3. It is difficult for shadows to occur, and the visibility of the lower cargo space L3 is improved. In addition, since the light guide 50 is arranged at the back, it becomes a blind spot for a user who puts and removes the luggage with respect to the lower cargo space L3, and the appearance of the lower cargo space L3 is improved.

When the partitioning device main body 40 is a shielding device such as a tonneau cover device, the shielding sheet is provided so that the shielding sheet can be pulled out backward with respect to the sheet storage device, and the light guide is provided in the front-rear direction when the light guide is provided at the lower part of the sheet storage Can be arranged closer to the rear seat than the rear door.
In the case where the partition device main body 40 is a member such as a rear shelf, if the light guide is provided relatively in front of this member, the light guide can be disposed closer to the rear seat than the rear door in the front-rear direction. it can.

  Of course, even if the light guide 50 is provided at a position where d2 ≧ d1, the shade of the lower cargo compartment space L3 becomes visible when the cargo is put in and out of the lower cargo compartment space L3, but the visibility of the lower cargo compartment space L3 is improved. The improvement effect can be obtained by the cargo compartment partitioning device without the load.

(2) Functions and effects of the cargo compartment lighting device for vehicles including the cargo compartment partition device:
Hereinafter, the operation and effect of the cargo compartment lighting device 3 for an automobile including the cargo compartment partition device 4 will be described.
When the luggage compartment partition device 4 is attached to the deck side trim 20 and the shielding sheet 44 is pulled out, the light from the ceiling illuminator 11 is blocked by the partition device body 40 when described with reference to FIG. And does not reach the lower cargo space L3. Here, when the deck side trim 20 is directly illuminated and the lower cargo space L3 is illuminated by the illumination, the light from the illumination is blocked by placing a high load near the deck side trim. And a great shade is produced. Moreover, when a user puts a part of the body into the lower cargo space L3, the body blocks light from the illumination and a large shade is generated. Therefore, the visibility of the lower cargo space L3 is lowered.
If the number of light sources provided in the deck side trim is increased, the structure of wiring and the like is complicated and the cost is increased. In addition, if the amount of light from one light source is increased, the amount of heat from the light source increases, making it difficult to ensure heat dissipation.In addition, too strong light from the light source provided on the deck side trim enhances the appearance and design of the luggage compartment. Will be reduced.

  When the cargo compartment partition device 4 is attached to the deck side trim 20, as shown in FIGS. 6 and 7, the light emitted from the light passage portion 22 of the side wall portion to the vehicle width direction inner side (inner direction D 4). The light is incident on the light incident portion 51 of the light guide 50 provided in the partition device main body 40, and the incident light exits downward from the light emitting portion 52 of the light guide 50 and extends downward from the partition device main body 40. Illuminate the lower cargo space L3. Since the light LI1 is emitted downward from the light guide 50 provided in the partitioning device main body 40, not from the deck side trim 20, a large shade is generated even if a high load is placed near the deck side trim. Absent. Further, even when the occupant puts a part of the body into the lower cargo space L3, no great shade is produced. Therefore, according to the luggage compartment lighting device 3 including the main cargo compartment partition device 4, the visibility in the lower cargo compartment space L3 is improved.

  Moreover, since the light source is not provided in the luggage compartment partition device 4 attached to and detached from the side wall portion, the visibility of the lower cargo compartment space L3 is improved by the luggage compartment partition device 4 having a simple structure. Further, the light from the side wall portion is illuminated through the light guide 50 to the entire lower cargo compartment space L3, and there is no need to increase the number of light sources provided in the side wall portion of the cargo compartment space. Therefore, the luggage compartment lighting device 3 can ensure a good appearance and design of the cargo compartment while suppressing the complexity of the structure such as wiring and cost increase.

  Furthermore, when the user opens the rear door and uses the luggage compartment, the cargo compartment lighting device 3 is arranged in the vehicle width direction D3 from the attachment position of the sheet storage device 42 that is the innermost part of the cargo compartment space L1 when viewed from the user. The entire lower cargo space L3 can be illuminated almost uniformly over the entire length. When the entire lower cargo space L3 is illuminated almost uniformly, a large shade and a user's body do not cause a large shade, and the visibility of the lower cargo space L3 is ensured. In addition, since the light source is provided on the side wall portion of the cargo space, the light guide 50 functions as indirect illumination that illuminates the entire lower cargo space L3 from the lower part of the cargo compartment partition device 4 that is likely to be a blind spot of the user. Is good in appearance and design. Furthermore, since it is not necessary to provide a light source in the luggage compartment partition device 4 that is repeatedly attached to and detached from the side wall, obstruction to the attachment / detachment operation of the cargo compartment partition device 4 due to wiring is suppressed, and damage to the light source is also suppressed.
