Publication number: 20100133894Abstract: The degree of freedom in design is increased while maintaining strength by enabling a decorative member to be disposed without thinning a wheel main body. A wheel is made up of a wheel main body 1 which is made up of a rim portion 10 and a disc portion 11 and which has a vent hole 141 in the disc portion 11 and a decorative member 2 made from a resin which is held in at least the disc portion 11 and is observed from the vent hole 141. Since the decorative member 2 is observed in the vent hole 141, the wheel main body 1 including spoke portions 14 does not have to be thinned. In addition, since the design of the decorative member is observed in cooperation with the design of the disc portion 11, the degree of freedom in design is increased.Type: ApplicationFiled: January 28, 2010Publication date: June 3, 2010Applicants: TOYODA GOSEI CO., LTD., TOPY KOGYO KABUSHIKI KAISHAInventors: Kazuo Takeda, Tomokazu Nishikawa, Daiichiro Kawashima, Tatsuya Oba, Tatsuya Arakawa, Koji Murakami, Kenichi Sakanoshita
