Abstract
A bearingof a support portionfor rotatably supporting a shaftof a rotating bodyto be measured with respect to the magnitude of unbalance thereof is formed into a hollow U-shape and has formed therein an injection portfor injecting a gas towards the shaft. As the shaft can be supported and floats without making contact with the bearing by virtue of the gas injected from the injection port, the friction can be made small and, hence, a change in rotational speed can be made small. The number and position of the injection ports are determined as required.
