PROBLEM TO BE SOLVED: To obtain a drink agitating and mixing device for automatic vending machine which has strong washing force by making the top edge part of a bowl-shaped container curved and folded back in an inward radial direction over all circumference. SOLUTION: The top edge part 11b of a bowl-shaped container 11 is curved and folded back in the inward radial direction over all circumference. In the part 11b, an annular locking nail 11b1 formed in a lower part is snap-interfitted into an annular locking projection 11d1 formed on the upper edge of a lower part 11d of the container 11 and flexibly engaged to be connected to the part 11d. The contact parts of them are subjected to water stopping with an O ring 11e. After a prepared beverage is discharged from the container 11, a motor 13 is operated to rotate an agitating blade 12, and hot water is supplied to the container 11 through a hot water supply tube 15. The hot water in the container 11 is agitated horizontally by the blade 12, also pushed in an outward radial direction by centrifugal force to be guided to the part 11b curved in the inward radial direction, and circulated downward to be also agitated vertically.
