摘要： A rotary anode X-ray tube, comprising a rotor, a stationary structure, a dynamic pressure slide bearing formed between the rotor and the stationary structure, the stationary structure having a lubricant storage chamber and provided with a lubricant passageway, and a vacuum vessel. Holes are formed in the stationary structure extending from the lower edge surface along the tube axis and not to cross the lubricant storage chamber and the lubricant passageway. Heat transfer members for the stationary structure having a heat conductivity higher than that of the stationary structure are inserted into the holes, respectively. A heat transfer member having a heat conductivity higher than that of the inner cylindrical structure of the rotor is bonded in a cylindrical form to the outer circumferential wall of the inner cylindrical structure constituting a bearing. A heat transfer member can be mounted to each of the rotor and the stationary structure.
