A steering wheel core structure comprises a hub core, polygonal in cross section with diametrically opposed, parallel peripheral faces; a spoke core with a U-shaped central portion brought into engagement with the peripheral surfaces of the hub core to clamp the same and held at the central portion between an enlarged end of the hub core and a hub bracket. The hub bracket has a finger engaged in a peripheral cut of the hub core so as to prevent relative rotation between the hub bracket and the hub core, a pair of upstanding portions engageable with upstanding portions of the spoke core so as to prevent relative rotation between the spoke core and the hub core, and a pair of horn contact portions and a pair of hub cover mounting portions cooperating to hold therebetween radial portions of the spoke core so as to prevent the spoke core from falling off from the hub bracket. The spoke core is secured at the central portion to the hub cover by projection welding and the hub bracket is secured at its base portion to the hub core by projection welding.
