On the other hand, the upper surface of the bottom wall 2A of the heat insulation wall 2 is inclined low toward the front of the fan case 23, and the drain pan 41 is formed at the bottom thereof, and the drain pan 41 is connected to the drain hose 42. A continuous drain hole 43 is formed.

In the castle grown in the cooler 27, it is heated and dissolved by a dehumidifying heater (not shown), but this dehumidifying water flows through the upper surface of the bottom wall 2A, collects into the sump 41 and drains the drain hole 43 from the drain hose 42. Entered and discarded.

In addition, the condensation water etc. which flowed down from the inner insect intake 18 and the outer insect absorbing part 19 are also gathered in the drainage receiver 41 below, and it drains in the same shape.

Here, a plurality of products are mounted and displayed on the shelf 32, but when a customer's hand touches the shelf 32 at the time of taking out the product, the horizontal force is applied to the shelf 32.

However, in the structure of the present invention, even when the shelf 32 tries to move backward by such an action force, the base 52A of the engaging piece 52 is the upper part of the cutting groove 53 on the front side of the bracket 31. (53B) Engagement of each engaging piece 52 and cutting grooves 53, 54, and 55 because it cannot move in contact with the horizontal stop portion 55D of the front surface or cutting groove 55; The relationship is maintained.

Therefore, the engaging pieces 52, 52 and the cutting grooves 53, 54 or the engaging pieces 52, 52 and the cutting grooves 54, only by unnecessary horizontal movement by the customer, etc. Since the engagement with 55 is not released, the fall of the article on the shelf 32 and the shelf 32 is surely prevented even if the customer presses the shelf, for example, in the direction of pulling down the entirety of the shelf 32.

In the embodiment, the engaging piece 52 and the cutting grooves 53, 54, and 55 are formed in an approximately L-shaped shape in which either the base 52A or the bottom faces forward. The present invention is effective even in the form of an L-shaped shape in which any of them are directed backward.

In that case, of course, the upper portion 53B is the front side of the lower portion 53A. In addition, although the shape of the cutting grooves 53, 54, 55 was changed back and forth in the Example, even if it was set as the shape of the cutting groove 53 or the cutting groove 55 both before and after.

Thus, according to the shelf apparatus S of this invention, the fall of the goods on the shelf 32 and the shelf 32 is prevented by a simple structure, without impairing the attachability of the shelf 32 to the bracket 31. It becomes possible.

As described above, according to claim 1 of the present invention, even when the shelf on the bracket is to be moved in the horizontal direction, the shelf cannot be moved because the engaging piece on the bottom surface contacts the high portion of the bottom of the cutting groove formed on the bracket.

Therefore, even if the customer's hand touches it and moves it horizontally unnecessarily to raise the engagement piece upward, the engagement relationship between the engagement piece of the shelf and the cutting groove of the bracket is not released. To prevent the falling of the shelf and articles on the shelf.

Further, according to claim 2, even if the shelf on the bracket is to be moved in the horizontal direction, the shelf is not movable because it is in contact with the horizontal stop of the cutting groove formed in the bracket of the engaging piece on the lower surface of the shelf.

Again, when the shelf is lifted up, the shelf is not removed from the bracket because the fitting piece abuts against the upward stop of the cutting groove.

Therefore, as in claim 1, the fall of the shelf and the article on the shelf can be prevented reliably.

In addition, since the engagement piece is guided to the inclined portion of the cutting groove when the shelf is installed, the engagement piece is smoothly inserted into the recessed portion for engagement.
