To make it easier to take out supplementary items from a case on a rack.

Supports 4 are stood in the front and rear parts of the rack main body 1, and support angles 20 made of angle steel are attached at the supports 4, A support angle 20 consists of a bottom plate 20a and a side plate 20b. When a can storage case 21 is pit on the bottom plates 20a of the support angles 20, the bottom of the storage case 231 is supported by the upper surfaces of the bottom plates 20a of both front and rear support angles 20. By such a structure, the can storage case 21 which is put in the bottom plates 20a of the front/rear support angles 10 is supported in the direction of slanting of each slant angle 16.
