To provide a method for casting a rim and a disk of an elastic wheel in which productivity is excellent, and the cost for a die is reduced.

(1) In the method for casting a rim and a disk, a rim part and a disk part are separated from each other by using a core 18 to form an elastic member installation space, a runner 19 is formed between the rim part and the disk part, and the rim 11 and the disk 12 of an elastic wheel 10 are cast in one step. (2) In the casting method, a plurality of molten metal feed ports 20 are provided, and the rim and the disk are cast by a multi-gate system. (3) In the casting method, a horizontal die 25 is fitted to an upper die 26 side, molten metal is poured in a cavity, the horizontal die 25 is elevated together with the upper die 26 while the horizontal die is closed after the molten metal is solidified, and a casting is released from a lower die 24.
