An attachment structure is a structure that attaches an annular brake disk to an attachment object member that is a wheel or a disk body of a railway vehicle. The attachment structure includes a fastening member and an elastic member. The elastic member is disposed between a nut of the fastening member and the brake disk. The elastic member has a member body having a tubular shape, and a flange. The flange is connected to an end part on the nut side among two end parts of the member body. The flange protrudes outward from the member body and contacts an outer peripheral portion of the nut.

A wheel includes a boss, a rim, and a web. The rim includes a tread and a flange. A center of the rim in the axial direction of the wheel is disposed closer to the flange in the axial direction than a center of the boss in the axial direction is. The web has a plate-thickness center line that has a linear shape when the wheel is viewed in its longitudinal section. When an angle that the plate-thickness center line forms with the axial direction is denoted by a, a distance in the axial direction from a side face of the rim to an outer end of the plate-thickness center line is denoted by Pw, a length of the rim in the axial direction is denoted by Wr, and Pw/Wr is denoted by L, the wheel satisfies the expression L≥0.0223α−1.363. Where, the angle α is 90° or less.
