Abstract
A device for holding a small weight rotor body on a shaft of a balance testor. The shaft has a stopper portion engaging the rotor body inserted on the shaft, and has a pair of axially spaced apart annular grooves to which respective O-rings are fitted. The O-rings generate a frictional force for fixedly connecting the rotor body on the shaft during the measurement of the unbalance.
