To prevent deterioration of the durability of a peripheral rotary wheel body by enabling high retention of the mounting accuracy of each of partial wheel bodies relative to a hub.SOLUTION: A peripheral rotary wheel body 5 is composed of a combination of partial wheel bodies 50 separate in a circumferential direction. Respective ends of the partial wheel bodies 50 adjacent in the circumferential direction overlap in the circumferential direction. In addition, at an overlapping portion of the ends in the circumferential direction, contact parts 53 disposed in contact with each other in a radial direction are formed.SELECTED DRAWING: Figure 2
【課題】ハブに対する各部分輪体の取付精度を高く維持できるようにして、周部回転輪体の耐久性の低下を避けられるようにする。【解決手段】周部回転輪体5が、周方向での複数個に分割された部分輪体50の組み合わせで構成され、周方向で隣り合う位置の部分輪体50の端部同士が、周方向で互いに重複し、かつ、端部の周方向での重複箇所に、径方向で互いに当接する当接部53が形成されている。【選択図】図2
