To improve a reduction effect on vibration around a vehicle longitudinal axis of a wheel.SOLUTION: A vehicle wheel 10, 10A to D according to an embodiment includes: a cylindrical wheel rim 18; an annular mass member 22 disposed along a circumferential direction of the wheel rim 18; and an annular rubber member 24 disposed between the wheel rim 18 and the mass member 22. On a cross section cut in an axial direction X of the vehicle wheel, an interface 26 between the wheel rim 18 and the rubber member 24 has a first arc A1 expanding to a radial outer side Ro and an interface 28 between the rubber member 24 and the mass member 22 has a second arc A2 expanding to the radial outer side Ro.SELECTED DRAWING: Figure 2
【課題】ホイールの車両前後軸周りの振動に対する低減効果を向上する。【解決手段】実施形態に係る車両用ホイール10,10A~Dは、筒状のホイールリム18と、該ホイールリム18の周方向に沿って配される円環状のマス部材22と、ホイールリム18とマス部材22との間に介在する円環状のゴム部材24と、を備える。車両用ホイールの軸方向Xに切断した断面において、ホイールリム18とゴム部材24との界面26が半径方向外側Roに膨らむ第1の円弧A1を持ち、ゴム部材24とマス部材22との界面28が半径方向外側Roに膨らむ第2の円弧A2を持つ。【選択図】図2
