  The present invention relates to a showcase, and more particularly, to a showcase in which a plurality of product placement shelves for product display are vertically installed in a case body.

  A product mounting shelf that is vertically installed in a plurality of stages inside a case body of this type of showcase includes a bracket member, a slide mechanism, and a shelf board, and the shelf board is assembled to the bracket member via the slide mechanism. (Also referred to as a shelf assembly). The bracket member is in the form of a substantially right triangle, with the base positioned rearward and facing the vertical direction, while the hypotenuse is positioned below, and the side connecting the tip of the hypotenuse and the right-angled corner of the base is horizontal and forward. A pair of left and right shelves, which are arranged in a manner and are provided with a plurality of locking pieces projecting rearward from the bottom side (rear end) in the vertical direction, and the locking pieces are arranged on the back side inside the case body. It is a pair of right and left that are locked by engaging with locking holes drilled at regular intervals in the vertical direction on the front surface of the column. The shelf plate has a rectangular flat plate shape in which the upper surface constitutes a placing surface on which the product is placed, and is attached to each bracket member via a slide mechanism so as to straddle between these bracket members. It is erected. Such a shelf plate is movable forward and backward with respect to a bracket member locked to a pair of left and right shelf posts by a slide mechanism (for example, see Patent Document 1).
