PROBLEM TO BE SOLVED: To provide a wheel inexpensive and capable of suppressing occurrence of noise.SOLUTION: A wheel comprises a hub part made of a light alloy, and a boss 20 made of a metal of higher strength than the light alloy and provided at the axial center of the hub part by casting for insertion of an axle, in which rotational force is transmitted between the axle and the hub part via the boss 20. The boss 20 comprises a large teeth portion 22 that is formed, as a power transmission part between the boss and the hub part, in a radial wave shape as viewed in the axial direction and has a high tooth height h2, and a small teeth portion 21 that is formed, on a nearer side to the axis than the large teeth portion 22, in a radial wave shape as viewed in the axial direction and has a tooth height h1 lower than that of the large teeth portion 22.SELECTED DRAWING: Figure 2 【課題】廉価かつ音の発生を抑制することができるホイールを提供する。【解決手段】軽合金製ハブ部と、軽合金より高強度の金属製でかつハブ部の軸心に鋳込みにより設けられ、車軸が挿通されるボス２０とを備え、回転力が車軸とハブ部との間でボス２０を介して伝達されるホイールであって、ボス２０は、ハブ部との間の動力伝達部として、軸線方向から見て波形で放射状に形成され、歯の高さｈ２が大きな大歯部２２と、大歯部２２よりも軸心側において、軸線方向から見て波形で放射状に形成され、歯の高さｈ１が大歯部２２よりも小さな小歯部２１とを備えている。【選択図】図２
