PROBLEM TO BE SOLVED: To make timing to generate an alarm proper by generating the alarm at the time of applying a seat belt judgement switch and a drive position judgement switch and temporarily stopping the alarm at the time when the drive position judgement switch is applied after application of a reverse position judgement switch. SOLUTION: A seat belt judgement switch 1 is put on at the time when a seat belt is not worn and puts on a pilot lamp 3. A drive position judgement switch 5 is put on when a transmission is shifted to a drive, and a reverse position judgement switch 9 is put on when the transmission is shifted to a reverse position. When the seat belt is not worn and the transmission is shifted to a drive position, alarming sound is generated, and the larming sound is stopped after specified time passes. In case of changing from the drive position over to the reverse position, an alarm circuit is cut out and the alarming sound is stopped. Consequently, it is possible to certainly alarm wearing of the seat belt by generating the alarming sound at the most suitable timing. |
