PROBLEM TO BE SOLVED: To provide a hooking height state detection tool capable of detecting a hooking height and determining normality or abnormality based on a fact that there is a sag due to the deadweight of a rope, and provide a safety belt with a rope having the hooking height state detection tool at a substantially intermediate position.SOLUTION: A hooking height state detection tool is attached to a substantially intermediate part of the length of a rope of a safety belt having a belt, the rope, and a hook. The hooking height state detection tool comprises: an inclination angel sensor for detecting whether a hook side of an attachment portion is higher or lower than a belt side of the attachment portion in a lengthwise direction of the rope; and normality/abnormality determination means for determining whether an inclination state of the output is normal or abnormal. |
