    • A wheel cover which can be mounted on wheels having the same standardized diameter irrespective of types of the wheels. The wheel cover has a plurality of clips, for sandwiching a rim flange of the wheel, fixed at positions proximate to a peripheral edge of a disc-shaped wheel cover body, with the clips spaced at predetermined intervals. The clips and the wheel cover body are connected with each other through a plane fastener. A plurality of first plane members constituting the plane fastener is installed at positions proximate to the peripheral edge of the underside of the disc-shaped wheel cover body, with the first plane members spaced at predetermined intervals in the circumferential direction of the disc-shaped wheel cover body. A second plane member engaging the first plane member elastically is installed on each clip. Each clip has a sandwiching portion for sandwiching the rim flange elastically or by the clamping force of a screw means.
    • 可以安装在具有相同标准直径的车轮上的轮罩,而不考虑车轮的类型。 轮盖具有多个夹子,用于夹持轮的轮缘凸缘,固定在靠近盘形轮罩主体的周边边缘的位置处,夹具以预定间隔隔开。 夹子和车轮盖体通过平面紧固件相互连接。 构成平面紧固件的多个第一平面构件安装在靠近盘形轮罩主体的下侧周缘的位置处,其中第一平面构件在盘形轮的圆周方向上以预定间隔隔开 盖体。 弹性地接合第一平面构件的第二平面构件安装在每个夹子上。 每个夹子具有用于将弹性边缘或通过螺钉装置的夹紧力夹住边缘凸缘的夹持部分。
