[0008]

Although the product display shelf 36 is mounted on the bracket 34, a gap 46 is provided between the product display shelf 36 and the rear surface of the display room 17, that is, the partition wall plate 14.
Occurs. Particularly, as described above, the notch 3 of the bracket 34 is pulled by pulling the commodity display shelf 36 toward the front side.
When the 4a and the protrusion 36a of the product display shelf 36 are engaged with each other, the gap 46 is largely opened. Until now, it was not considered that the gap 46 affects the cooling efficiency. However, the cool air discharged from the cool air discharge port 23 may pass through this gap, and the display room 1
It has been discovered that the air curtain formed on the front surface of 7 may be divided in the direction of the gap, and the flow on the front surface of the display room 17 may be weakened and disturbed. Then, it was found that due to the splitting of the cool air, the ability of the air curtain to shut off the outside air was lowered, and the ability to cool the inside of the display room 17 was adversely affected.

Therefore, in order to reduce the gap 46, it is conceivable that the notch 34a of the bracket 34 and the protrusion 36a of the commodity display shelf 36 are engaged by pushing the commodity display shelf 36 inward. However, since the weight of the product 38 may be applied to the stopper 38 of the product display shelf 36, the product display shelf 36 may move to the front side. Then, when the product display shelf 36 moves to the front side, the notch 3
4a and the protrusion 36a are disengaged, and the product display shelf 36
May come off the bracket 34, which is dangerous. Therefore, it is not possible to form the notch 34a and the protrusion 36a by engaging the product display shelf 36 inward.

Further, it is difficult to bring the product display shelf 36 having rigidity into close contact with the rear surface of the display room 17 only by mounting it on the bracket 34.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a cooling open showcase capable of closing a gap between a rear surface of a display room and a product display shelf. To do.
