Abstract

Abstract A pair of portions of a steering wheel which are normally gripped by a driver''s hands are slightly reduced in diameter or cross sectional area as compared with the other portions thereof and are integrally covered with a soft, elastic and non-slippery material such as foamed synthetic plastic or leather to have a diameter or cross sectional area greater than that of the other portions of the wheel so that the driver may grip the steering wheel easily and firmly without slippage. Transmission of vibrations from the steering wheel to the driver''s hands may be sufficiently dampened, and the appearance of the steering wheel may be enhanced materially when the color of the grip portions is different from that of the other portions.
