PURPOSE:To facilitate casting work and reduce the weight of a wheel by installing a wheel bearing through a disc brake fitted onto the both side surfaces of an inner wheel. CONSTITUTION:A disc brake 3 is fixed onto the both side surfaces 17 of an inner wheel 13 by a fixing tool, and the center of the brake disc 3 is accorded with the center of a body 1, and a bearing 2 is installed into a center hole. Said bearing 2 is constituted of a bearing outer shaft installation hole 14 and a collar 15. Therefore, a large cavity 16 is formed in the center part of the body 1, and a thick part for connecting the bearing 2 and a spoke 12 can be removed, and the strength of the wheel can be increased. |
