The attached mounting plate 47 is removed from the rear shelf frame 22. In this state, the LED illumination member 42 attached to the attachment plate 47 is replaced, and the LED illumination member 42 is attached again in the reverse procedure.

  Thus, since the LED lighting device 41 including the LED lighting member 42 can be attached across the rear portions of the pair of left and right brackets 20 and 20 that support the shelf plate 23, the LED lighting device 41 is integrated. By installing the shelf plate 23 on the bracket 20, it is possible to configure the shelf device 4 including the illumination device 41, and assembling workability is improved.

  Therefore, even if the height of the shelf device 4 is changed, the LED lighting device 41 that illuminates the shelf is also changed at the same time along with the height change. It becomes possible to simplify the work.
