Be sent out. For this reason, it is easy for cold air to escape to the front outside of the showcase. Therefore, in order to prevent cold air leakage and to secure an air path for the cool air curtain, an entire guard plate 4 using a transparent acrylic plate or the like is attached to the lower edge of the opening 2, and is raised in the direction of the opening 2.

As shown in FIG. 4, the front guard plate 4 is formed of an elongated plate having a length equal to the width of the opening 2, and a plurality of fixing holes 7 for fixing are provided at a lower portion at appropriate intervals (in the example shown in the figure). 3
The lower part of the front guard plate 4 is fixed to the upper part of the front of the showcase main body 1 with screws using a mounting hole 7 and the side part is, for example, as shown in FIG. As shown in the cross-sectional plan view, the side end is abutted on the inside of the side plate 3 and, in this state, along the length direction (height direction) along the corner formed on both sides of the front and rear surfaces of the end of the front guard plate 4. A side plate having a triangular cross section is attached as a reinforcing member 15, and the side end of the front guard plate 4 is pressed and fixed to the inside of the side plate 3 from both the front side and the back side.

In this case, the reinforcing member 15 is also made of an acrylic plate, and is fixed to the front guard plate 4 and the side plate 3 with an adhesive.

[0007]

As a structure for fixing the front guard plate 4 to the side plate 3 side, as described above, the reinforcing member 15 is used.
In the method in which the side plate 3 is a transparent plate, the reinforcing material 15 and the adhesive are visible from the outside of the side plate 3, and the appearance is not good.
