1. A vehicle wheel comprising:
two annular rim members disposed on a same axis;
at least one annular flange member disposed between the two rim members so as to have a same rotation axis as the two rim members;
a securing member that secures a positional relationship between adjacent members among the two rim members and the at least one flange member;
a plurality of body springs that each connect adjacent members among the two rim members and the at least one flange member; and
a plurality of linking springs that are linked to the plurality of body springs so as to restrict relative displacement between the plurality of body springs, wherein
at least part of each body spring in the plurality of body springs in a width direction of the vehicle wheel protrudes further to an outer side in a radial direction of the vehicle wheel than the rim members and the flange member, and the plurality of body springs are provided at intervals over an entire circumferential direction of the vehicle wheel, and
the plurality of body springs are attached to the rim members and the flange member so that an axis of each body spring in the plurality of body springs forms an inclination angle of less than 30 degrees with respect to the radial direction of the vehicle wheel at peripheral portions of the rim members and the flange member.
