PROBLEM TO BE SOLVED: To provide a safety belt usage state confirmation system capable of reliably confirming that a safety belt is used on site, a safety belt usage state confirmation method, and a hook of a safety belt.SOLUTION: A sensor 103 that detects an electronic signal in an inside region E of a hook 101 and a cable 11 disposed at an attaching part 2 that generates an electronic signal react with each other in a non-contact manner. The sensors react with each other when the hook 101 is actually attached to the attaching part 2, and the attaching part 2 and the cable 11 that generates an electronic signal are positioned in the inside region E. The sensors react with each other automatically if a user WP actually attaches the hook 101 to the attaching part 2, without the user WP performing a special operation. A second controller can easily detect the attachment of the hook 101, and when the hook 101 is not attached, a warning device 5 issues a warning, thereby confirming the usage state of the safety belt 100. |
