AI Technical Summary
Technical Problem
Conventional vehicle wheels have limitations in the design and structural integrity of the members between the spokes, which affect their aerodynamics and design freedom.
Method used
The vehicle wheel design incorporates an extension portion with a plate-like member between adjacent spoke portions, featuring a reinforcing portion that extends axially and is separated from the hub and spokes, enhancing structural integrity and aerodynamics while allowing for increased design freedom.
Benefits of technology
The new design improves aerodynamics by reducing air resistance and allows for lighter and more aesthetically appealing wheel designs with enhanced structural support.

Abstract
To improve the components between spokes in vehicle wheels. [Solution] The vehicle wheel comprises a cylindrical wheel rim portion, a hub mounting portion attached to the axle hub on the vehicle side, a plurality of spoke portions extending radially from the hub mounting portion and joined to the wheel rim portion, and an extension portion positioned between at least one pair of adjacent spoke portions among the plurality of spoke portions in the circumferential direction of the wheel rim portion. The extension portion has a plate-like portion extending from the wheel rim portion toward the hub mounting portion and separated from both the hub mounting portion and the pair of spoke portions, and a reinforcing portion protruding from at least one surface of the plate-like portion and extending in the axial direction of the wheel rim portion.
