PROBLEM TO BE SOLVED: To obtain a vending machine wherein the lifetime of equipment can be extended by preventing the temperature rise of a motor shaft of a blower fan and the heat exchange efficiency can be improved by concentrating air sent from the blower fan into a heat transmission range of a heater. SOLUTION: In a heat exchange chamber 8, a heat reflection plate 20 for intercepting radiant heat radiated from a heater 7 toward a blower fan 2 and a wind directing plate 30 for concentrating air distributed by the heat reflection plate 20, to the heater 7 are installed on a floor 19 of a commodity storage box 1. The heat reflection plate has an approximately triangular section having an apex on the side of the blower fan in the plane view or has an approximately conical shape, and the wind directing plate 30 has an approximately chevron-shaped section being narrower on the side of the heater 7 in the plane view or has an approximately truncated conical shape having a top plate and a bottom plate opened.
