PROBLEM TO BE SOLVED: To provide a lifting device capable of effectively preventing foreign matter entering a rounded passage from being lifted with a game ball.SOLUTION: A nearly arc-like rounded passage extended along an outer peripheral surface of a lower roller of a lifting device body includes: guide plates 150 and 150 separately disposed at an interval wider than a diameter of a game ball, and guiding the game ball along a rotation direction of the lower roller; and a pressing plate 151 disposed at an interval narrower than the diameter of the game ball in a portion to an adjacent guide plate 151, and including a pressing surface 151a for pressing the game ball against the lower roller. At least one portion of the pressing surface 151a is formed between the guide plates 150 and 150 so as to be deformed elastically. |
