PROBLEM TO BE SOLVED: To achieve weight saving and reduce manufacturing costs in a saddle-riding type vehicle wheel manufactured by using die casting.SOLUTION: A saddle-riding type vehicle wheel is a die-casting product and comprises a rim, a hub, and a plurality of spokes connecting the rim and the hub. The hub comprises a plurality of connection parts connecting an inner peripheral part and an outer peripheral part, extending from the inner peripheral part to the outer peripheral part in a radial direction, and arranged at intervals in a circumferential direction. The plurality of connection parts include a plurality of first connection parts located at one side in a rotation axis direction of the wheel and a plurality of second connection parts located at the other side. When the hub is viewed from the rotation axis direction, each first connection part is located between two second connection parts adjacent to each other in the circumferential direction, and each second connection part is located between two first connection parts adjacent to each other in the circumferential direction. A through hole penetrating in the rotation axis direction is formed between the first connection part and the second connection part adjacent to each other in the circumferential direction.SELECTED DRAWING: Figure 3

【課題】ダイカストを用いて製造された鞍乗型車両用ホイールにおいて、軽量化を実現するとともに、製造コストを低くする。【解決手段】本発明の実施形態による鞍乗型車両用ホイールは、ダイカスト鋳造品であり、リムおよびハブと、リムとハブとを繋ぐ複数のスポークとを備える。ハブは、内周部と外周部とを繋ぐ複数の繋ぎ部であって、内周部から外周部へ径方向に延びるとともに周方向に間隔を空けて配置された複数の繋ぎ部を有する。複数の繋ぎ部は、ホイールの回転軸線方向における一方側に位置する複数の第１繋ぎ部と、他方側に位置する複数の第２繋ぎ部とを含む。回転軸線方向からハブを見たとき、各第１繋ぎ部は、周方向に互いに隣接する２つの第２繋ぎ部の間に位置しており、各第２繋ぎ部は、周方向に互いに隣接する２つの第１繋ぎ部の間に位置している。周方向に互いに隣接する第１繋ぎ部と第２繋ぎ部との間には、回転軸線方向に貫通する貫通穴が開いている。【選択図】図３
