To secure a design property when a wheel does not rotate and achieve reduction of air resistance when the wheel rotates.SOLUTION: A vehicle wheel cover includes: a body member which is attached to a wheel of a vehicle wheel and integrally rotates with the wheel when the wheel rotates; an auxiliary member which is disposed at the outer side of the vehicle wheel relative to the body member and can move in a wheel rotation axis direction relative to the body member; and weight members which are disposed offset from a rotation center of the wheel to a radial outer side between the body member and the auxiliary member and moved to the radial outer side by a centrifugal force acting when the wheel rotates. The body member has guide parts each of which extends from the rotation center side to the radial outer side and guides the weight member. The auxiliary member has shutter parts each of which extends in a radial direction and is supported at one end in the radial direction by the body member. Further, the shutter part contacts with the weight member at a radial position set according to a magnitude of the centrifugal force and the other end in the radial direction moves in a rotation axis direction in response to movement of the weight member in the radial direction.SELECTED DRAWING: Figure 8

    【課題】ホイールの非回転時にデザイン性を確保しつつホイールの回転時に空気抵抗の低減を図ること。【解決手段】車両用ホイールカバーは、車輪のホイールに取り付けられ、ホイールの回転時にホイールと一体で回転する本体部材と、本体部材よりも車輪外側に配置され、本体部材に対してホイールの回転軸方向に移動可能な補助部材と、本体部材と補助部材との間においてホイールの回転中心から径方向外側にずれて配置され、ホイールの回転時に作用する遠心力により径方向外方に移動するウェイト部材と、を備える。本体部材は、回転中心側から径方向外方に延在し、ウェイト部材を案内するガイド部を有する。補助部材は、径方向に延在し、径方向一端部で本体部材に支持され、遠心力の大きさに応じた径方向位置でウェイト部材に接し、ウェイト部材の径方向への移動に応じて径方向他端部が回転軸方向に移動するシャッタ部を有する。【選択図】図8
