PROBLEM TO BE SOLVED: To provide a split wheel capable of preventing a side ring from rotating without using a bolt or a screw. SOLUTION: In this split wheel 10, a side ring 12 is split to the wheel body 11, and a seal ring 14 is located outside a first lock rib 21 and a second lock rib 22 in a wheel axial direction, and a key 51 for preventing rotation is inserted from the inside in the wheel axial direction beyond the side ring 12. Under condition that the second notch 28 and the first notch 27 are aligned in a wheel axial direction, a key 51 is inserted in the keyway 52 formed by both of the second notch and the first notch from the outside of the wheel, and a side ring 12 is prevented from rotating relative to the wheel body 11.
