良に至る。[Problems to be Solved by the Invention] However, in the former case, if starting and braking of the anode are repeated, loosening occurs, causing vibration and noise. In the latter, since the brazing material must be brazed together with the rotor instead of the target alone, the brazing material and its melting point (or brazing temperature) are limited, and a relatively low melting point brazing material must be used. Then, when the brazing material comes out to an unnecessary part when brazing, the target is at a high temperature of about 1000 ° C. during the operation of the X-ray tube, so that the brazing material evaporates, and the degree of vacuum deterioration and X-ray This causes metal deposition on the inner and outer envelopes of the tube container, and eventually leads to poor withstand voltage.
