<p>PROBLEM TO BE SOLVED: To provide a dynamic balancing device capable of more accurately measuring a dynamic balance of a tire from a change in a vibration condition and the like when a tire is rotated. SOLUTION: By means of a piezoelectric element arranged in contact with a spindle housing surface, an exciting force is measured. The tire and the spindle are rotationally driven by means of a rotation drum rotating while perpendicularly pressing the tire with a first pressing load in the predetermined direction to the rotational axis of the spindle. In this way, the dynamic balance can be measured more accurately. When the first pressing load is set to 40-60 kgf, more accurate measurement can be carried out.</p> |
