Further, although only the first inclined support member 13 and the second inclined support member 14 are interposed between the support member 11 and the shelf board 12, an inclined support member having the same configuration is further interposed. It is also possible to. Further, since the support member 11 provided with the slider 113 and the slide mechanism 114 is illustrated, the work of placing the product for sale can be easily performed by pulling out the shelf plate 12 forward with respect to the support member 11. It becomes possible. However, in the present invention, it is not always necessary to slide the shelf board.

Further, in the above-described embodiment, since the support member 11 provided with the support portion main body 111 having the two side wall portions 111c is applied, a large dimension along the vertical direction of the support member 11 itself is secured. It becomes possible to secure the desired strength without doing so, and it is possible to further increase the storage capacity of the lower product storage shelf, but it is not always necessary to apply a support member having two side wall portions. Absent.

Further, in the above-described embodiment, the shelf board 12 can be tilted by 9 ° with respect to the support member 11, but the tilt angle does not necessarily have to be 9 °, and if necessary. It can be set arbitrarily. In this case, the tilt angle of the first tilt support member 13 and the tilt angle of the second tilt support member 14 do not necessarily have to be the same. Further, between the support member 11 and the first inclined support member 13, the support member 11 is provided with the first protrusion 112d, and the first inclined support member 13 is provided with the first guide groove 13f. The first protrusion and the first guide groove may be provided in reverse directions. Similarly, between the first inclined support member 13 and the second inclined support member 14, the first inclined support member 13 is provided with the second protrusion 13d, and the second inclined support member 14 is provided with the second guide groove 14d. However, the second protrusion and the second guide groove may be provided in the opposite direction. In the embodiment, the second inclined support member 14 is operated first, and then the first inclined support member 13 is operated, but the second inclined support member 14 and the first inclined support member 13 are operated. The operating procedure may be reversed.

Furthermore, in the above-described embodiment, the inclined support members 13 and 14 provided with the guide grooves 13f and 14d are moved in the front-rear direction with respect to the inclined shafts 112c and 13c to lock the protrusions 112d and 13d. The positions of the surfaces 13f3, 13f4, 14d3, and 14d4 are changed, but the present invention is not limited to this. For example, the protrusions are arranged so as to be movable, and the position of the locking surface can be changed by moving the protrusions. It may be configured to change.
