US Patent 9302535 Automobile wheel

Each spoke portion includes spoke projecting threads on both sides thereof, and a reinforcing plate portion is formed so as to protrude from a side edge of each of the spoke projecting threads outward in a spoke widthwise direction. The reinforcing plate portion is formed continuously with an inter-spoke plate portion extended from a fitting portion of a disc flange portion to a wheel radially inner side, and forms an integral plate surface with the inter-spoke plate portion. With this configuration, it is possible to reduce imbalance of rigidity of the spoke portion in a radial direction, and to increase rigidity of an automobile wheel.
