ABSTRACT:
A steering wheel structure includes a steering wheel ring, a first spoke extending downward from a steering shaft and carrying the steering wheel ring on the steering shaft and, an air bag case disposed on a tip end portion of the steering shaft. An air bag received in the air bag is case in a folded state and an inflator is provided for inflating the air bag with gas. An igniter is used to ignite a material in the inflator to produce the gas.
