ABSTRACT:
A steering wheel core is provided including a boss, a ring and a spoke. The spoke is composed of a cover member having predetermined rigidity, and a flexible insert embedded in the cover member. The insert is formed with a bent portion. The cover member has a reduced thickness portion near the bent portion of the insert. Due to the reduced thickness portion, the cover member has a lower strength near the bent portion than that of remaining portions thereof. As a result, the cover member ruptures near the bent portion if an impact is applied to the steering wheel, so that the spoke is deformed to absorb the impact. However, the spoke will not rupture completely due to the insert flexing at its bent portion.
