PROBLEM TO BE SOLVED: To increase productivity by reducing manufacturing time and improving casting quality, when manufacturing a magnesium alloy wheel by die-casting.SOLUTION: At each connection portion 160 between a spoke portion 150 and a rim portion 140, there are provided a bottom surface portion 161, inclined surface portions 162 and 163. The bottom surface portion 161 is narrower than the rim portion 140 with respect to a side-to-side direction, and extends in a direction orthogonal to a radial direction. The inclined surface portions 162 extend in directions away from each other, from both ends, with respect to a circumferential direction, of the bottom surface portion 161, to portions spaced apart from the bottom surface portion 161, in the rim portion 140. The inclined surface portions 163 extend in directions away from each other, from both ends, with respect to the side-to-side direction, of the bottom surface portion 161, to portions spaced apart from the bottom surface portion 161, in the rim portion 140.SELECTED DRAWING: Figure 7

    【課題】ダイカスト鋳造でマグネシウム合金製のホイールを製造する際、製造時間を短くしつつ鋳造品質を向上させることによって生産性を高める。【解決手段】スポーク部150とリム部140の連結部160には、底面部161並びに斜面部162及び163が形成されている。底面部161は、左右方向についてリム部140より幅が狭く、径方向に直交する方向に沿っている。斜面部162は、周方向について、底面部161における両端部から、リム部140における底面部161から離隔した部分まで、互いに離隔する方向に延びている。斜面部163は、左右方向について、底面部161における両端部から、リム部140における底面部161から離隔した部分まで、互いに離隔する方向に延びている。【選択図】図7
