To provide a wheel structure which can suppress a length of a spoke part.SOLUTION: A structure of a cast wheel 20 comprises: a hub part 21 which is supported by an axle; a rim part 22 on which a tire is mounted; and a plurality of spoke parts 23 extending between the hub part 21 and the rim part 22. In this structure, the hub part 21 comprises a hub body 31 for supporting a bearing, annular outer peripheral wall parts 32 which are so provided on an outer periphery of the hub body 31 as to be separated from each other. A plurality of protrusions 36, which project to an outer peripheral side, are provided on outer peripheral sides of the outer peripheral wall parts 32. The plurality of spoke parts 23 are divided into a plurality of partial spoke parts 23 and constitute a plurality of spoke groups 23A, and the plurality of spoke parts 23 in each of the plurality of spoke groups 23A extend toward the rim part 22 from each of the plurality of protrusions 36.SELECTED DRAWING: Figure 2
【課題】スポーク部の長さを抑えることができるホイール構造を提供する。【解決手段】車軸に支持されるハブ部21と、タイヤを装着するリム部22と、前記ハブ部21と前記リム部22との間に渡る複数のスポーク部23と、を備えるキャストホイール20の構造において、前記ハブ部21は、ベアリングを支持するハブ本体31と、前記ハブ本体31の外周に離間して設けられる環状の外周壁部32と、を備え、前記外周壁部32の外周側には、外周側に突出する複数の凸部36を備え、前記複数のスポーク部23は、一部の複数のスポーク部23毎に分けられて複数のスポーク群23Aを構成し、前記複数のスポーク群23Aの各々における複数のスポーク部23は、前記複数の凸部36の各々から前記リム部22に向けて延出ている。【選択図】図2
