Then the automatic vending machine is provided with the base 6 consisting of a substrate 7 and fixation metal 8 which is welded onto the substrate and has a groove 81 wherein the neck part of the leg part 4 is inserted in the center and forms a gap 82 wherein the head part 41 is inserted. The automatic vending machine 1 is installed on the base 6 set at an installation place by fixing the head part 41 of the leg 4 to the fixation metal 8. Even if the center of gravity moves forward when the external door 3 is opened, the center of gravity is in the substrate 7 and the automatic vending machine is prevented from being fallen down without requiring any anchor bolt.
