PURPOSE: To prevent an automatic vending machine loading a goods housing rack in which plural passages extending up and down as meandering forward/ backward are formed from being stagnated in the passage and to enable it to be installed in space where no automatic vending machine loading the goods housing rack in which the passages ≥4 are formed before and behind in parallel can be installed.

CONSTITUTION: Three passages 31 formed before and behind in parallel, and surface members 33, 34 whose right and left terminals are supported with a pair of side plane members forming the right and left side planes of the passage in such a way that they can be moved forward/backward freely and which form either road surface before and behind of the passage are provided. Also, the surface member is comprised of plural members arranged in parallel upward/ downward and whose right and left terminals are connected with each other via a connecting piece. Furthermore, a member whose right and left terminals are connected with each other via a connecting piece 35 interlocking with the upward/downward movement of the connecting piece 35 supported movably freely in up and down directions can be moved forward/backward.
