1. A motor vehicle steering wheel, comprising a steering-wheel rim, a cast hub, flat steel deformable spokes connecting the steering-wheel rim to the cast hub for mounting on a steering shaft, associated free ends of the spokes being cast into the cast hub in a cast-in area, and each spoke having in the cast-in area a passage bore which extends in an axial direction of the steering wheel and is penetrated by hub material during the casting process to form a tension-rod connection between hub material located above and below the spoke at the entry area of said spoke into the hub, wherein said passage bore is arranged directly adjacent to the entry area of the spoke into the hub, said hub having a rolling step at the outer peripheral edge of the hub on the underside of the hub, a portion of said spoke immediately curving away from the rim in a gradual manner at the rolling step, the spoke gradually continuing to curve as a function of distance from the hub such that the spoke curves towards the rim at a predetermined distance from the hub, whereby said curvature of said spoke in cooperation with said rolling step permits said spoke to deform in a defined manner having a large radius.
