As shown in Figure 5, the lighting locking plate 33 is fixed to the guide part 31 with the screw 32, the guide part 31 is inserted into the guide holding groove 29 of the lighting holders 21a and 21b from its end, and the guide part 31 is slid together with the lighting locking plate 33 to align it with the installation position of the lighting 23.
Next, the end of the light 23 is pushed into the light retaining plate 33 from below, and the light 23 is attached to the light holders 21a and 21b.
Then, the wiring T connected to the end of the lighting 23 is accommodated in the wiring housing 27 through the wiring insertion opening 27e.

The reflector 10 is disposed across the light holder 21a at one end in the width direction and the light holder 21b at the other end in the width direction, and is placed on the reflector placement portion 35 of each of the light holders 21a, 21b.
Then, each end 10a in the width direction of the reflector 10 is disposed so as to be swallowed into the swallowing portion 41 formed between the wiring accommodating portion 27 and the mounting portion 25 of the lighting holders 21a and 21b.

Next, the effects of this embodiment will be described.
According to the above-described embodiment, the lighting 23 can be easily installed by bridging between the mounting portions 25 of the lighting holders 21a, 21b provided along the longitudinal direction of the plant cultivation shelf 1 at one end and the other end of the width of the plant cultivation shelf 1, and the wiring T can be stored in each wiring storage portion 27 of the lighting holders 21a, 21b, resulting in good workability.

The lighting holders 21a and 21b can be attached at any position in the longitudinal direction of the plant cultivation shelf 1 at one end side and the other end side in the width direction of the plant cultivation shelf 1, respectively, so that even if the pitch of the lighting 23 needs to be changed depending on the type of plant or the growing condition, the position can be easily adjusted.
Since the lighting 23 is provided in the width direction of the plant cultivation shelf 1, unevenness in the light reaching the plants can be reduced compared to when the lighting is provided in the longitudinal direction.

In each of the lighting holders 21a, 21b, the wiring storage section 27 for storing the wiring T is provided closer to the end in the width direction of the plant cultivation shelf 1 than the mounting section 25 for mounting the lighting 23, so that the wiring T is unlikely to hang on the inside (the center in the width direction) of the plant cultivation shelf 1 and does not get in the way. In addition, for a worker who performs work such as installing lighting at the end in the width direction of the plant cultivation shelf 1, the wiring storage section 27 is located in front, making it easy to store the wiring T.
By providing the wiring storage section 27, the wiring T of each lighting 23 can be stored in the wiring storage section 27 as it is, and it is not necessary to fasten the wiring T to the plant cultivation shelf 1 or to tie the wiring T when there are a plurality of wirings T, so that the workability is good and the design is good since the wiring is not exposed.
Each lighting fixture 21a, 21b is provided with a reflector mounting portion 35 and a gripping portion 41 for gripping each widthwise end portion 10a of the reflector 10 above the mounting portion 25, so that the reflector 10 can be easily installed.
Since the reflector 10 is provided above the lighting 23, the light emitted upward from the lighting 23 can be reflected toward the cultivation space 9, so that the irradiation efficiency of the lighting 23 is good.
A mesh plate 37 is provided in each wiring storage section 27 of the lighting holders 21a and 21b, and the mesh plate 37 has a notch or is short, and the wiring T is inserted between the notch or the mesh plates 37, 37, so that the wiring T of the lighting 23 can be stored in the wiring storage section at any position.
Since each screw fixing portion 45 of the light holders 21a, 21b is provided with a space for receiving the shaft portion of the screw 43, chips from the screw 43 fixing the light holders 21a, 21b do not fall onto the plants.

The mounting positions of the lighting holders 21a and 21b can be adjusted by sliding the guide portions 31 into the guide holding grooves 29, so that the position of the lighting 23 can be easily adjusted.
The lighting locking plate 33 is an elastic body having an arc shape with an opening at the bottom, so that the lighting 23 can be easily attached by pushing the lighting 23 in from below.

The present invention is not limited to the above-described embodiment, and various modifications are possible 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, 21b may be arranged along the longitudinal direction of the plant cultivation shelf 1, and may not necessarily be fixed to the auxiliary material 8a attached to the end of the vertical bar 8, but may also be fixed to the main body of the vertical bar 8, for example, with screws fastened from below.
