PROBLEM TO BE SOLVED: To provide structure capable of detecting the generation of abnormality in output signals from sensors 5, 5, in accompaniment to the generation of a defect in a constitutive component, a wire or the like, as to a load measuring instrument for calculating a load acting between an outer ring 1 and a hub 2, based on a phase difference existing between the fellow signals from the pair of sensors 5, 5. SOLUTION: The presence of the abnormality in the output signals from the sensors 5, 5 is determined when a difference between frequencies or periods of the output signals from the sensors 5, 5, or a difference between a rotation speeds found based on the respective frequencies or periods, exceeds a preset threshold value, by an abnormality monitor (not shown). Constitution of this manner is adopted to solve the problem hereinbefore. COPYRIGHT: (C)2008,JPO&INPIT
