Abstract:
A steering wheel includes (a) a core member having a boss portion, a spoke portion, and a rim portion, the spoke portion stretching between the boss portion and the rim portion; and (b) a polyurethane member covering at least the rim portion of the core member, the polyurethane member having a specific gravity of 0.7 to 0.9 and a Shore A hardness of 45 to 60. A steering wheel proper defined as being a combination of the core member and the polyurethane member has a weight of 1.0 to 2.5 kg. This steering wheel is satisfied in both of weight reduction and maintenance of moment of inertia necessary for steering wheel.
