Is fixed with the clasp 14. The motion identification circuit 5 that determines whether or not an abnormal situation is detected based on the movement of the bather 2 and the signal read by the water level detector 4 and an abnormality determination signal input from the motion identification circuit 5 indicate that the abnormal situation exceeds a limited time. A controller 7 composed of a timer for outputting a signal to the outside is incorporated in the detection unit 13, and when the bather 2 causes an accident, the alarm 8 and the warning light 9 are activated and the radio 1
0, it is configured to be able to report to a remote place by the wire reporting device 11.
