Then, in the double type movable rack in which the racks in the front row can be laterally moved, the fixed transfer plate 18 can be detachably attached to the top plate 3 of the fixed rack provided with the top plate upper reinforcing member 17 of the fixed rack 1. The fixed transfer plate 18 is provided with a guide rail 19 which also serves as a guide for the sliding door 6 for the fixed shelf and the movable shelf 2, and the movable transfer plate 24 is detachably provided on the top plate 4 of the movable shelf. A movable shelf roller fixing plate 23 for fixing the movable shelf roller 22 of the movable shelf 2 to the movable transfer plate 24 is provided, and the movable shelf roller 22 provided at the end of the movable shelf roller fixing plate 23 is replaced with the movable shelf roller 22. A technique to prevent falling by loosely fitting the receiving portion 21 of the guide rail 19. It was adopted means.

[0005]

[Action]

 By adopting the above technical means, the present invention is provided with an integrated dual-purpose guide rail for guiding a sliding door roller for a fixed shelf and a moving shelf roller for a moving shelf with a simple structure. Therefore, it has a simple structure and has a sufficient fall prevention function in terms of strength.
