ABSTRACT:
An air bag, a control device and a rider or operator removal detecting part are disposed in an operator's jacket. An air bag device body includes air inflating chambers, an ECU, a battery, a radio receiver, a main switch and a warning device incorporated into the jacket. In response to a synchronizing signal transmitted from a vehicle-body-side radio transmitter, a vehicle-body-side electric wave signal generating part and a rider-side reference waveform signal generating part, respectively, generate an electric wave signal and a comparison signal in a synchronized state with a signal comparing part determining a phase difference between both signals. When a delay quantity or a change of the delay quantity of the electric wave signal from the electric wave signal generating part is increased, the ECU detects a removal of a rider for informing an air bag drive part.
