A wheel (100) is provided with a hub section (10), a rim section (20), and a plate section (30). The rim portion (20) includes a tread surface (21) and a rim (22). The center (Cr) of the rim section (20) in the axial direction of the wheel (100) is disposed closer to the rim (22) than the center (Cb) of the hub section (10) in the axial direction. The plate section (30) has a linear plate thickness center line (A) in a longitudinal cross-sectional view of the wheel (100). The wheel (100) satisfies L > = 0.0223 [alpha]-1.363, where [alpha] is the angle formed between the plate thickness center line (A) and the axial direction, Pw is the distance in the axial direction from the side surface (24) of the rim section (20) to the outer end (Aa) of the plate thickness center line (A), Wr is the length of the rim section (20) in the axial direction, and L is Pw/Wr. Wherein the angle alpha is 90 degrees or less.

    车轮(100)包括轮毂部(10)、轮辋部(20)、以及板部(30)。轮辋部(20)包含踏面(21)和轮缘(22)。车轮(100)的轴向上的轮辋部(20)的中央(Cr)在轴向上被配置为比轴向上的轮毂部(10)的中央(Cb)更靠近轮缘(22)。板部(30)在车轮(100)的纵剖视图中具有直线状的板厚中心线(A)。将板厚中心线(A)与轴向所成角度记为α,将从轮辋部(20)的侧面(24)到板厚中心线(A)的外端(Aa)在轴向上的距离记为Pw,将轮辋部(20)在轴向上的长度记为Wr,将Pw/Wr记为L时,车轮(100)满足L≥0.0223α‑1.363。其中,角度α为90°以下。
