ABSTRACT:
A steering wheel comprises a steering wheel core having a ring core piece, a boss disposed downwardly of the center of the ring core piece and spoke core pieces, extending upwardly from the boss in the radial outer directions, for connecting the ring core piece to the boss. Provided at the ends of spoke core pieces extending from the boss are connecting parts, each formed of die casting metal, for connecting the spoke core pieces to ring core piece. A plurality of ribs formed integrally with the connecting parts are protruded from the upper surfaces of the connecting parts on the side of spoke core pieces. A pad, the upper surface of which is made substantially horizontal, is stretched over the boss to vicinal portions to the connecting parts. The surfaces of ring core piece and also of connecting parts including the ribs are covered with coating layers formed of synthetic resin by the injection molding. Each layer is arranged to have a substantially horizontal upper surface so that the upper surfaces of connecting parts are flush with the upper surface of pad.
