PROBLEM TO BE SOLVED: To improve the lifting efficiency of a lifting device by satisfying opposite requests, which are related to the level of the pressure of Pachinko balls, such as the prevention of clogging of Pachinko balls and smooth reception. SOLUTION: In this device, the lower end portion of a column 8, with which a spiral groove group is formed on an outer peripheral surface, is concentrically surrounded with a short cylinder 40, respective introduction holes formed in the peripheral direction of the short cylinder 40 are formed into height dimension so as to face plural lines of spiral groove groups, and an insertion rolling plane surrounding the short cylinder 40 is constituted so that the central side of the column 8 can be inclined lower than the outside. Further, the insertion rolling plane is composed of a downstream rolling plane 22 adjacently surrounding the short cylinder 40 and an upstream rolling plane 25 surrounding the downstream rolling plane 22 through a step part 23, and the step part 23 is constituted so that a Pachinko ball group rolled from the upstream rolling plane 25 can be overlapped to plural steps on the downstream rolling plane 22 and plural Pachinko ball groups can be introduced from a single introduction hole while the column 8 is once rotated. Thus, the lifting efficiency of a lifting device for Pachinko ball can be improved.
