PROBLEM TO BE SOLVED: To provide a vending machine which avoids the occurrence of a part to be hardly cooled in a machine and also shortens a time till uniformity is achieved in merchandise temperature inside the machine. SOLUTION: In the vending machine, a lower in-chamber fan 20 disposed in the left lower part of the machine blows cool air which cools the merchandises stored in a rack part by passing through a wind tunnel 21 arranged on the wall surface of the machine. The vending machine is also provided with a second wind tunnel 31 which guides the cool air blown by a second lower chamber fan 30 to the merchandises stored in the rack part by arranging the second lower chamber fan 30 at the right lower part of the machine in addition to the fan 20. Thus the collision of the cool blows in two directions causes the largest cool air flow at the center part of the lower chamber 8, the cool air comes round to the lower sides of cool air blow outlets 21a and 31a after being pushed back by the collision of the cool blows and, then, the cool air is diffused to the whole lower chamber 8.
