PURPOSE:To provide a warning device having only one indicator which can give an alarm for the defective mounting of a seat belt and the failure of an occupant protection device, and also can inform an occupant of a broken electric circuit when the occupant protection device is not connected to the indicator. CONSTITUTION:The switching actions of switching transistors 8 and 11 are made different in response to the warning signal and the signal-indicating the connecting condition of a failure warning indicating device 3 which are outputted from a seat belt warning circuit 7 and a failure detection circuit 9 respectively, so that the indication pattern of an indicator 10 is thereby changed. |
