PROBLEM TO BE SOLVED: To provide a vending machine capable of appropriately realizing local temperature adjustment and the whole temperature adjustment with a simple structure without increasing the number of components. SOLUTION: In the vending machine 1, a duct plate 50 forming a cylindrical circulation duct 30 is arranged to face to a back wall of a product storage chamber 10. When a volume of air sent out by an in-chamber fan 60 is plenty since an upper inlet 51 is located near an upper end of a product rack 20, the air reaches to an upper part of the product rack 20, and is sucked in the circulation duct 30 from the upper inlet 51 via a wide range of the product rack 20. When a volume of air sent out by the in-chamber fan 60 is small since intermediate inlets 52a, 52b formed on the duct plate 50 are located near a lower end of the product rack 20, the air is sucked in the circulation duct 30 from the intermediate inlets 52a, 52b via a range near a lower end of the product rack 20.
