Abstract: Disclosed is a steering wheel equipped with an air bag system. The steering wheel has a controller having a processor which outputs a trigger signal for actuating an air bag in accordance with the strength of an impact arising from a collision of a car, upon sensing the impact, and a memory which stores a process by this processor; an inflator which generates a gas in accordance with a signal outputted from the controller; and an air bag which is inflated with the gas supplied from the inflator. Between the opposite surfaces of a controller case and an inflator case, there is provided a heat-insulating layer. This heat-insulating layer serves to reduce heat passing from the inflator to the controller when the air bag is inflated. Consequently, contents stored in the memory mounted in the controller will never be destroyed by heat, and it is possible to analyze the process of operation of the processor after a collision of a car body.
