<P>PROBLEM TO BE SOLVED: To provide an anode rotating type X-ray tube with high reliability in which a rotor can make a stable rotation movement. Ž<P>SOLUTION: In the X-ray tube, a cylindrical rotor includes a cylindrical inner face and a fixed axle is inserted into the hollow cylinder to support the rotor rotatably. A pillar-shape bearing part is installed in the fixed axle and includes an opposed face opposed to the cylinder inner face. A bearing groove is formed in the opposed face and a dynamic bearing is formed on the opposed face by lubricant filled in the gap. At both ends of the pillar-shape bearing part, a thin structure is provided at the end of the pillar-shape bearing part by a circular circumference groove formed by cut-out and a cylindrical flange part at the outer periphery of the circular circumference groove.
