ABSTRACT:
A steering wheel having an impact energy absorbing member capable of absorbing a predetermined amount of impact energy while being attached in a predetermined position to the steering wheel through its upper portion. The steering wheel includes a boss assembly provided at the center of the steering wheel and including a metallic core. The impact energy absorbing member which is disposed above the metallic core and which is capable of deforming by being reduced in size generally in the axial direction of a steering shaft when it receives an impact force applied in the axial direction, and a pad disposed over the impact energy absorbing member to cover the same. The impact energy absorbing member has attachment extensions projecting outward from its upper peripheral portion generally parallel to its central portion. An attachment hole is formed in each attachment extension to enable the impact energy absorbing member to be fixed to the steering wheel with a screw. The attachment hole is opened in the peripheral portion thereof on the pad outer edge side when impact force is applied to the pad.
