When the compressor 18 and the blower 16 of the cooling device are operated, the cooler 14 performs a cooling function. The cool air in the duct 11 cooled by the cooler 14 is sucked up by the blower 16 and blown upward, and is discharged into the storage chamber 9 from the cool air discharge port 12 at the uppermost part.

A part of the cool air rising inside the duct 11 flows into the cool air passage 31 of the shelf device 2 from each through hole 33... And moves forward through the cool air passage 31. It is blown downward from the outlet 32 at the front end. At this time, a bent portion 23A is formed at the front end of the reinforcing plate 23, and since the cool air passage 31 is narrowed at this portion, the cool air blown out from the outlet 32 is straightened, and the flow velocity is increased.

The cool air discharged or blown into the storage chamber 9 finally circulates from the cool air inlet 13 into the duct 11 (indicated by an arrow in FIG. 2). The holding member 5 is attached to the shelf support 26. The presser 5 is formed by bending a metal plate or integrally molding a hard synthetic resin, and as shown in FIG. 6, a main body 42, a handle piece 43 projecting forward from an upper edge of the main body 42, An insertion piece 44 protruding rearward from an upper side edge of the main body 42 and a holding piece 46 protruding laterally from a side edge of the main body 42 below the insertion piece 44 are integrally provided.

Here, the holding member 5 shown in FIG. 6 is attached to the shelf support 26 on the left side, and the one attached to the right shelf support 26 has a symmetrical shape to that of FIG. And A drop prevention portion 45 extending upward is formed at a rear portion of the insertion piece 44, and has a shape that can be inserted into and removed from the locking hole 27 of the shelf support 26.

3 can be inserted by setting it to a horizontal state, and insertion and removal can be easily performed by performing an operation opposite to that at the time of insertion.

At this time, since the position of the pressing piece 46 is set as described above, the pressing piece 46 comes into contact with or substantially comes into contact with the innermost portion of the upper surface of the bracket 22 (in an extremely close state). Thus, when the shelf 3 is pulled out to the front, even if the center of gravity moves forward, the bracket 2
The second claw 28 is lifted, so that the rear portion of the bracket 22 does not rise.

Further, the insertion piece 44 of the holding member 5 is connected to the shelf support 2.
6 can be easily inserted into and removed from the locking holes 27 of the rack 6, so that the rack device 2 can be easily mounted and removed even when the mounting position of the rack device 2 is changed. Since the shelf support 26 is inclined such that the upper portion is rearward as shown in FIG. 3, the main body 42 of the holding member 5 is held in a state in which it is in close contact with the front surface of the shelf support 26. Therefore,
The pressing tool 5 does not come off due to vibration or the like.

In the embodiment, the present invention is applied to an open showcase having a so-called movable shelf, but the present invention is not limited to this.
The present invention is also effective for ordinary shelf devices.
