Abstract
A device for measuring the imbalance of a disc-like object has at least three load sensors having cantilevers for supporting the object at their corresponding measuring points selected, with a same angular distance therebetween, on a measuring circle which is concentric with a circular through-hole of the object. Each of the caltilevers is extended tangential to the measuring circle and directed perpendicular to the line of sight in the same sense when viewed from the center of the through-hole. A positioning device positions the center of the through-hole in the object relative to the load sensors, and a calculator device for calculating the imbalance of the object using the data supplied from the plural load sensors.
