A wheel (100) comprises a boss portion (10), a rim portion (20), and a plate portion (30). The rim portion (20) includes a tread (21) and a flange (22). The plate portion (30) connects the boss portion (10) and the rim portion (20). In the longitudinal cross-sectional view of the wheel (100), the plate portion (30) has a straight plate thickness center line (A) that is inclined so as to approach the flange (22) side toward the outer side in the radial direction. In the longitudinal cross-sectional view of the wheel (100), the outer end (Aa) of the plate thickness center line (A) is between the flange (22) and a center (211) of the tread (21) in the axial direction of the wheel (100).
车轮(100)具备轮毂部(10)、轮圈部(20)、以及板部(30)。轮圈部(20)包括踏面(21)和凸缘(22)。板部(30)连接轮毂部(10)和轮圈部(20)。在车轮(100)的纵剖视下,板部(30)具有直线状的板厚中心线(A),其以随着朝向半径方向的外侧而向凸缘(22)侧接近的方式倾倒。在车轮(100)的纵剖视下,板厚中心线(A)的外端(Aa)在车轮(100)的轴方向上位于凸缘(22)与踏面(21)的中央(211)之间。
