Abstract
A steering wheel having a ring portion, a boss portion arranged at the center of the ring portion, and a spoke portion connecting the boss portion with the ring portion, and in which the boss portion includes a boss and a boss plate, the boss having non-circular surfaces formed on the outer peripheral surface of the boss, the boss plate being connected with the spoke portion and with the upper surface of the boss by resistance welding and having flexible portions and restricting projections located around the center of the boss. The flexible portions provide an energy absorbing function and non-circular surfaces of the boss and the restricting projections of the boss plate prevent rotation of the boss plate relative to the boss when the welding portion happens to break.
