PURPOSE: To provide a show case capable of eliminating lateral movement of shelf boards caused by height adjust thereof, by equipping a pair of right and left rows of engaging holes with a narrow interval vertically arranged on a back board in a storage.

CONSTITUTION: Engaging hole rows 63A formed on a pair of right and left shelf support column 32 are constructed by arranging engaging holes 63 with narrow vertical width in the vertical direction with a constant small interval. A bracket has an upper claw 71 and a lower claw 72 to be inserted into the engaging holes 63 on the rear end, and the lateral width of a shelf board 8 is formed in an almost same dimension as the lateral width of the inside of a storage 4. When the height of the shelf board 8 is to be changed, the height is adjusted with a vertically fine interval by selecting engaging holes 63 to engage with the upper part claw 71 and the lower part claw 72. Since the bracket 7 is moved within only one engaging hole row 63A, a gap of ten and some mm existing between the shelf board end and the storage side wall is eliminated. Thus, the appearance of this show case is especially improved.
