[0015] The wiring accommodating portion 27 and the mounting portion 25 are integrally connected by a connecting portion 39. The connecting portion 39 is provided below the inner wall portion 27d, and a space surrounded by the connecting portion 39, the inner wall portion 27d, and the lower surface 7a of the vertical bar 8 or the plant cultivation floor 7 is defined as an engulfing portion 41 that engulfs the widthwise end portion 10a of the reflector 10.

[0016] As shown in FIG. 4, on one end side of the wiring accommodating portion 27, there is provided a screw fixing portion 45 for fixing the lighting fixture 21a to an auxiliary material 8a fixed to the end of each vertical bar 8 with a screw 43. The screw 43 is a tapping screw. The screw fixing portion 45 is a hollow portion and is a space for accommodating the shaft portion 43b of the screw 43 that stops its head against the auxiliary material 8a. The screw fixing portion 45 has a substantially rectangular cross-section. The auxiliary material 8a is formed by bending a strip-shaped plate material into a U-shape in side view, and has an upper protruding portion 46a and a lower protruding portion 46b protruding inward in the width direction of each vertical bar 8, and a connecting portion 46c between the upper protruding portion 46a and the lower protruding portion 46b. The lower protruding portion 46b is positioned with a space below the vertical bar 8. The connecting portion 46c is fixed to the vertical bar 8 by screwing with a screw 42 into a tapping hole 44 of the vertical bar 8. In the space between the lower protruding portion 46b and the vertical bar 8, the screw fixing portion 45 of the lighting fixture 21a is arranged, and the lower protruding portion 46b of the auxiliary material 8a receives the lower surface of the screw fixing portion 45. The lower surface of the lower protruding portion 46b is substantially flush with the lower surface of the lower wall 27b of the wiring accommodating portion 27.

[0017] Next, the attachment of the lighting fixture 21a, the lighting 23, and the reflector 10 will be described. As shown in FIG. 1, the lighting fixture 21a is installed between the vertical frames (width direction erection members) 6, 6 and is attached to each vertical bar 8. As shown in FIGS. 4 and 5, for the attachment of the lighting fixture 21a, at the end of the vertical bar 8, the screw fixing portion 45 of the lighting fixture 21a is inserted between the lower protruding portion 46b of the auxiliary material 8a attached to the end of the vertical bar 8 and the vertical bar 8, and the screw 43 is screwed in from one end side to fix the screw fixing portion 45 to the connecting portion 46c of the auxiliary material 8a. Similarly, on the other end side in the width direction, the screw fixing portion 45 of the lighting fixture 21b is also attached to the auxiliary material 8a of the vertical bar 8.

[0018] Next, the attachment of the lighting 23 will be described. As shown in FIG. 5, the lighting locking plate 33 is fixed to the guide portion 31 with the screw 32, the guide portion 31 is inserted into the guide holding grooves 29 of the lighting fixtures 21a, 21b from its end, and the guide portion 31 is slid together with the lighting locking plate 33 to align with the attachment position of the lighting 23. Next, the end of the lighting 23 is pushed into the lighting locking plate 33 from below to attach the lighting 23 to the lighting fixtures 21a, 21b. Then, the wiring T connected to the end of the lighting 23 is stored in the wiring accommodating portion 27 through the wiring insertion port 27e.

[0019] The reflector 10 is arranged to straddle between the lighting fixture 21a on one end side in the width direction and the lighting fixture 21b on the other end side in the width direction, and is placed on the reflector placement portions 35 of the respective lighting fixtures 21a, 21b. Then, each end 10a in the width direction of the reflector 10 is respectively swallowed into the swallowing portion 41 formed between the wiring accommodating portion 27 and the attachment portion 25 of the lighting fixtures 21a, 21b and arranged.

[0020] Next, the operation and effect of this embodiment will be described. According to the above-described embodiment, by installing the lighting 23 between the attachment portions 25 of the lighting holders 21a and 21b provided along the longitudinal direction of the plant cultivation shelf 1 on one end side and the other end side in the width direction of the plant cultivation shelf 1, the lighting can be easily attached, and the wiring T can be stored in the wiring storage portions 27 of the lighting holders 21a and 21b, so that the workability is good.

[0021] Since the lighting holders 21a and 21b can be attached at arbitrary positions in the longitudinal direction of the plant cultivation shelf 1 on one end side and the other end side in the width direction of the plant cultivation shelf 1, even when it is necessary to change the pitch of the lighting 23 according to the type of plant and the growth situation, the position can be easily adjusted. Since the lighting 23 is provided in the width direction of the plant cultivation shelf 1, unevenness of light hitting the plants can be reduced more than when provided in the longitudinal direction.

[0022] In each of the lighting holders 21a and 21b, since the wiring storage portion 27 for storing the wiring T is provided on the end side in the width direction of the plant cultivation shelf 1 rather than the attachment portion 25 for attaching the lighting 23, the wiring T is less likely to extend to the inside (center side in the width direction) of the plant cultivation shelf 1, so that the wiring T does not become an obstacle. Further, for an operator who performs lighting installation work or the like on the end side in the width direction of the plant cultivation shelf 1, since the wiring storage portion 27 is located in front, the storage work of the wiring T is easy. By providing the wiring storage portion 27, the wiring T of each lighting 23 can be directly stored in the wiring storage portion 27, and it is not necessary to fasten the wiring T to the plant cultivation shelf 1 or bundle them when there are a plurality of wirings T, so that the workability is good and the wiring is not exposed, so that the design property is good. Since each of the lighting holders 21a and 21b is provided with an engulfing portion 41 that engulfs each width direction end portion 10a of the reflector 10 and a reflector mounting portion 35 above the attachment portion 25, the construction of the reflector 10 can be easily performed. Since the reflector 10 is provided above the lighting 23, the light emitted upward by the lighting 23 can be reflected toward the cultivation space 9, so that the irradiation efficiency of the lighting 23 is good. In each wiring housing portion 27 of the lighting holders 21a and 21b, an eyelet plate 37 is provided. The eyelet plate 37 has a notch or is short, and since the wiring T of the lighting 23 is inserted between the notch or the eyelet plates 37, 37, the wiring T of the lighting 23 can be stored in the wiring housing portion at an arbitrary position. In each screw fixing portion 45 of the lighting holders 21a and 21b, a space for receiving the shaft portion of the screw 43 is provided, so that the chips of the screw 43 for fixing the lighting holders 21a and 21b do not fall on the plants.

[0023] The attachment positions of the lighting holders 21a and 21b can be aligned by sliding the guide portion 31 in the guide holding groove 29, so that the position of the lighting 23 can be easily adjusted. Since the lighting locking plate 33 is an arc-shaped elastic body with an open bottom, the lighting 23 can be easily attached by pushing it in from below.

[0024] The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention. The lighting 23 is not limited to LED lighting, and may be a fluorescent lamp. The lighting holders 21a and 21b may be provided along the longitudinal direction of the plant cultivation shelf 1, and are not limited to being fixed to the auxiliary material 8a attached to the end of the vertical bar 8. They may be fixed to the main body of the vertical bar 8 with, for example, screws that are fastened from below.
