Abstract
A striking energy absorbing structure for a steering wheel is composed of a cover member, an energy absorbing member of a brittle plastic filling the inside of the cover member, and a horn switch member buried therebetween. Also disclosed is a method of manufacturing the above-described striking energy absorbing structure. The energy absorbing member is molded by casting a brittle plastic material into the inside of the cover member. In this cast molding, the horn switch member is previously set inside the cover member, so that the three members, that is, the cover member, the horn switch member and the energy absorbing member are simultaneously integrated with each other.
