A turning behavior control device for a vehicle includes a yaw rate detector, a front wheel suspension, a rear wheel suspension, a brake device, a hydraulic pressure supplier, and a travel controller. The left and right front wheels of the vehicle are steered wheels and drive wheels. The travel controller includes a deviation value calculator configured to calculate a deviation between a standard yaw rate for determining a degree of understeer during turning of the vehicle and a yaw rate detected by the yaw rate detector, and a braking force controller configured to output, to the hydraulic pressure supplier, a first signal for applying braking forces to left and right front wheels in addition to a turning inner rear wheel when it is determined that the deviation calculated by the deviation value calculator exceeds a predetermined deviation reference value.

Turning behavior control device for vehicle

A vehicle wheel element structure includes a center disc member, abutment members, and wheel-element-side fastening surfaces. Disc members extend radially in an outer diameter direction from the center disc member. The center disc member includes a center bore and fastening holes. The abutment members are provided on an inner side of the center disc member. Each abutment member protrudes from a position that is away from an opening of a corresponding one of the fastening holes by a predetermined distance. Each abutment member protrudes by a predetermined amount with respect to a reference plane when the abutment member is fastened to a hub unit. The abutment members abut first on a hub-side fastening surface. The wheel-element-side fastening surfaces are provided on the inner side of the center disc member. Each wheel-element-side fastening surface includes the corresponding one of the openings.
