To make the automatic vending machine itself low cost and economical and to reduce its weight by allowing a push-out piece to push the rear part of the article in the other right or left commodity storage chamber when a driving motor reverses.

When the driving motor 17 rotates, the push-out piece 16 pushes the rear part of a commodity of one of the right and left commodity storage chambers 15. When the driving motor 17 reverses while the push-out piece 16 stays behind the commodity, the push-out piece 16 pushes the rear part of a commodity in the other commodity storage chamber 15. Consequently, the commodity in the two commodity storage chambers 15 can be carried out by the one driving motor 17 to decrease driving motors and carrying-out mechanisms to a half, and consequently, the automatic vending machine itself can be made low cost and economical. Further, the weight is reducible and the load of installation, movement, alteration, etc., is lightened.
