Abstract
A steering wheel has a substantially T-shaped groove, which is positioned on the side opposite to the side facing the driver, in a core portion provided at the center of the steering wheel. When a load is applied to the lowest portion of a steering wheel rim, bending moments are exerted on the steering wheel about the boss portion and deform the steering wheel about a line parallel to a line connecting two points where two lower spoke members on the core portion are secured to the steering wheel rim. The steering wheel simultaneously creates the predetermined magnitude of deformation due to the deformation of a top portion of the T-shaped groove which is bent in response to the intensive stress. When further load is applied to the steering wheel, angular moments are generated with the distal ends of the spoke members serving as bending portions about the line perpendicular to a line connecting two points where two lower spoke members in the core portion are secured to the steering wheel rim. At this time, the predetermined magnitude of deformation of the steering wheel can be maintained due to deformation of a leg portion of the T-shaped groove which is bent in response to the intensive stress.
