摘要： An automotive wheel that can prevent deformation of a back side opening edge of a wheel rim in a radial direction and reduce the weight of the wheel rim is proposed.Because the automotive wheel has a structure in which an annular rib section formed in a stepped manner at each of the inside and the outside and having a thinner wall thickness than the other part of a ledge section is circumferentially formed in the ledge section of the wheel rim, an effect of preventing the deformation of a back side opening edge of the wheel rim in a radial direction is improved by virtue of a shaping effect of the annular rib section, and a weight reduction effect can be provided in connection with the thinner wall thickness of the annular rib section.
