PROBLEM TO BE SOLVED: To provide a device for game media shortening a lifting stroke, or a distance, when the game media are lifted while increasing an upward gradient and miniaturizing the device. SOLUTION: A light load part 51 of a spiral body 50 is bent at a bend radius R2 smaller than a bend radius R1 of a heavy load part 55, and the load applied from the game media to the light load part 51 of the spiral body 50 when lifting the game media is small so that, even if the light load part 51 is bent at the small bend radius R2, there is no possibility of breaking. The light load part 51 is bent at the small bend radius R2 so as to shorten the stroke of lifting the game media. COPYRIGHT: (C)2005,JPO&NCIPI
