Patent number: 10232665Abstract: A wheel cover includes: a cover body having an engagement hole and configured to cover a design face of a wheel; and a cover fastener that is inserted through the engagement hole. A primary attachment member of the cover fastener includes: a supporter that supports a periphery of the engagement hole; a cylindrical portion that is inserted in a hub hole formed in the wheel; a coupler that couples the supporter and the cylindrical portion; and a hook extending from the cylindrical portion to an outer circumferential side of the cylindrical portion, the hook being contactable with an inner circumferential portion of the hub hole at a position spaced apart from an outer circumferential surface of the cylindrical portion. A secondary attachment member of the cover fastener has an insertion portion that is inserted in a space formed between the hook and the outer circumferential surface.Type: GrantFiled: April 11, 2017Date of Patent: March 19, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tomohiko Takeda, Masanobu Mizui, Noriyoshi Matsui, Makoto Nitta, Hiromichi Yamazaki, Yasuo Noji
