Abstract
Abstract A steering wheel main body comprises cover members for covering a metal ring core (5) and metal spoke cores (6A,6B,6C), respectively, and a pad, situated substantially in a central upper portion of the steering wheel which is formed integrally with such cover members. A boss (8) is connected through a connecting part (21) with the metal spoke cores (6B,6C), which are arranged on opposite sides of the steering wheel and formed into a united body. The boss (8) is situated below the metal ring core (5) and the metal spoke cores (6B,6C) are connected to the boss (8) and to the other metal spoke core (6A) through sub-connecting parts (22) to thereby form an opening (23), and an air bag device is mounted through the opening. This permits completion of the assembling operation of the steering wheel with ease. After completion of the assembling of the steering wheel, that completed assembly is mounted onto the top end portion of a steering shaft.
