Wheel For Railway Vehicle

Abstract: A wheel (100) comprises a boss part (10), a rim part (20), and a plate part (30). A rim width center (Cr) is located on a flange (22) side of the rim part (20) with respect to a boss width center (Cb). The plate part (30) has a linear plate-thickness center line (A) in a vertical cross-sectional view of the wheel (100). The plate-thickness center line (A) is inclined with respect to the radial direction of the wheel (100) so as to be farther from the flange (22) toward the outside in the radial direction. Letting Pw be the distance in the axial direction of the wheel (100) from a side surface (24) of the rim part (20) to an outer end (Aa) of the plate-thickness center line (A) and Wr be the length in the axial direction of the rim part (20), Pw/Wr is less than 0.40.
