To inhibit deterioration of casting quality in a case that a damper storage part is integrated with a hub part etc., secure strength of the damper storage part, and achieve sufficient weight reduction in a die cast wheel made of a magnesium alloy.SOLUTION: A die cast wheel (100) made of a magnesium alloy includes a rim part, a hub part (120), and spoke parts. The hub part includes an inner cylinder part (121), an outer cylinder part (122), a connection part (123), a damper storage part (124), and ribs (140) provided within the damper storage part and is integrally formed. Each rib has: a pair of first vertical wall parts (141) protruding from the connection part to the outer side in an axel direction; a lateral wall part (143) spreading in a direction intersecting with the axle direction and connecting the first vertical wall parts with each other; and at least one second vertical wall part (142) which protrudes from the lateral wall part to the outer side or inner side in the axle direction, extends in a circumferential direction, and connects the first vertical wall parts with each other.SELECTED DRAWING: Figure 8

    【課題】マグネシウム合金製のダイカストホイールにおいて、ダンパ収納部をハブ部等と一体化した場合の鋳造品質の低下を抑制し、且つ、ダンパ収納部の強度の確保と十分な軽量化とを両立させる。【解決手段】マグネシウム合金製のダイカストホイール(100)は、リム部と、ハブ部(120)と、複数のスポーク部とを備える。ハブ部は、内筒部(121)と、外筒部(122)と、連結部(123)と、ダンパ収納部(124)と、ダンパ収納部内に設けられた複数のリブ(140)とを含み、一体に形成されている。各リブは、連結部から車軸方向における外側に突出して径方向に延びる一対の第1縦壁部(141)と、車軸方向に交差する方向に広がり第1縦壁部を互いに接続する横壁部(143)と、横壁部から車軸方向における外側または内側に突出し、周方向に延びて第1縦壁部を互いに接続する少なくとも1つの第2縦壁部(142)とを有する。【選択図】図8
