Patent number: 6663188Abstract: A cover body (22) has mounting claws (25), which are provided on a peripheral part thereof and restrained by a wire ring (23) from deforming toward the center of the cover body. The cover body is attached to a disc wheel of a vehicle by these mounting claws in such a way as to cover an outer surface part of the disc wheel. In this wheel cover, the necessity for additionally attaching the wire ring to the cover body is eliminated by inserting the wire ring thereinto and performing die-forming. Further, the stiffness of the cover body can be enhanced. Thus, a forming cycle time can be decreased. Moreover, the thickness of the cover body can be reduced.Type: GrantFiled: July 15, 2002Date of Patent: December 16, 2003Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Isao Sumi, Takashi Yamada, Eiji Saito, Keiichi Kitayama, Yasuhide Narita
