  In the product placement shelf 20 having the above-described configuration, guides 443 are formed on the left and right end portions 442a and 442b of the rear hanging portion 442 in the rear horizontal frame portion 44 of the shelf frame 40. It protrudes toward the rear at a position above the shelf plate 50 installed in the shelf frame 40.

  As a result, when attaching the product placement shelf 20 to the case body 1, the operator can visually align the guide 443 with the desired locking hole 12, and the guide 443 By aligning with the locking holes 12, the locking pieces 331 located immediately below the guide 443 can be inserted into the predetermined locking holes 12, respectively. That is, in the mounting operation of the product placement shelf 20, it is possible to insert the locking piece 331 into the predetermined locking hole 12 while visually confirming it through the guide 443.

  Therefore, according to the product placement shelf 20 of the showcase which is this Embodiment, the attachment operation | work with respect to the case main body 1 can be facilitated.

  According to the product mounting shelf 20, since the guide 443 is formed on the shelf frame 40 (rear horizontal frame portion 44), the following operational effects can be obtained.

  When the guide is formed on the bracket, the mounting position of the shelf frame with respect to the bracket is moved to the front side by the amount of forming the guide, and the longitudinal length of the product placement shelf is increased. If the front and rear lengths of the product placement shelf become large in this way, the front end of the product placement shelf obstructs the flow of air (air curtain) formed in the front opening of the case body, resulting in cooling performance. There is a risk of causing a decline. On the other hand, if the front and rear length of the product placement shelf is reduced in order to avoid obstruction of the air curtain, the area of the product placement surface will be reduced, and as a result, the number of product placement may be reduced. There is. On the other hand, in the product mounting shelf 20 according to the present embodiment, since the front and rear lengths of the product mounting shelf 20 are not increased, the air curtain is not hindered at the front end, and the cooling performance Can be satisfactorily exhibited, and the area of the product placement surface is not reduced, so that a reduction in the number of product placement can be prevented. That is, according to the product placement shelf 20 according to the present embodiment, since the guide 443 is formed on the shelf frame 40 (rear horizontal frame portion 44), a reduction in cooling performance and a reduction in the number of product placements are prevented. be able to.

  In addition, since the bracket is subjected to step bending, if the guide is formed on the bracket, there is a possibility that a left-right positional shift may occur between the locking piece and the guide. 20, since the guide 443 is formed on the shelf frame 40, it is possible to easily form the guide 443 immediately above the locking pieces 311, 331, and thereby the locking pieces 311, 331 and the guide 443 It is possible to suppress the left and right positional deviation between the two, and it is possible to facilitate attachment to the case body 1.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.

  For example, in the embodiment described above, the guides 443 are formed at the left and right end portions 442a and 442b of the rear horizontal frame portion 44. However, in the present invention, the guide is provided at either the left end portion or the right end portion of the rear horizontal frame portion. May be used, and it is not limited to the rear horizontal frame portion, and any portion may be used as long as it is located above the installed shelf board.

  In the above-described embodiment, the shelf frame 40 is movable along the front-rear direction with respect to the bracket 30. However, in the present invention, the shelf frame 40 is fixed to the bracket and moved along the front-rear direction. It may be regulated.

  As described above, the product placement shelf according to the present invention is useful for a showcase in which a product to be stored is held in a desired temperature state.
