1. A wheel to be used in a railway vehicle, the wheel comprising:
a boss that forms an inner circumferential portion of the wheel and into which an axle of the railway vehicle is to be inserted;
a rim that forms an outer circumferential portion of the wheel and includes a tread to come into contact with a top surface of a rail on which the railway vehicle travels and a flange protruding outward from the tread in a radial direction of the wheel, wherein the rim is positioned so as to be outward from the boss in a track-width direction; and
a web that has an annular shape and connects the boss and the rim, wherein
when the wheel is viewed in a longitudinal section,
the web has a plate-thickness center line having a linear shape and two ends, the plate-thickness center line being inclined such that the plate-thickness center line approaches a flange side as the plate-thickness center line extends outward in the radial direction, and
of the two ends of the plate-thickness center line, an outer end that is positioned more outward in the radial direction is positioned between the flange and a center of the tread in an axial direction of the wheel.
