Wheel For Railway Vehicle

Abstract: A wheel (100) comprises a boss part (10), a rim part (20), and a plate part (30). The rim part (20) includes a tread surface (21) and a flange (22). A center (Cb) of the boss part (10) in the axial direction of the wheel (100) is disposed closer to the flange (22) than is a center (Cr) of the rim part (20) in the axial direction. The plate part (30) has a linear plate-thickness center line (A) in a vertical cross-sectional view of the wheel (100). The wheel (100) satisfies L=0.053a-3.8626 where a is an angle between the plate-thickness center line (A) and the axial direction, Pw is a distance in the axial direction between a side surface (24) of the rim part (20) and an outer end (Aa) of the plate-thickness center line (A), Wr is the length of the rim part (20) in the axial direction, and L is a value obtained by dividing Pw by Wr. The angle a is 90° or less.
