Abstract
In a method of manufacturing a rotating anode type X-ray tube, in the step of checking the rotational balance of a rotary structure to which an anode target is fixed and correcting the rotational balance as required, the rotary structure is fitted on a stationary support jig which sprays a high-pressure gas from its interior, in place of a columnar stationary structure, to set the rotary structure upright. The rotary structure is rotated at a high speed while spraying the high-pressure gas, and the rotational balance of the rotary structure is checked. The rotational balance of a rotating unit can be checked in the air easily and at high precision, and can be adjusted directly in the outer air as required.
