Claims

[Scope of utility model registration request]

A rotating part in which a target, a rotor, and a rotating shaft are fixed to each other, and inner rings of two bearings spaced apart from each other are fixed to the rotating shaft via a sleeve, and this rotating part is connected to the bearing. A rotary anode X-ray tube having a fixed part rotatably supported through the rotating anode X-ray tube, wherein the bearing is an angular ball bearing, and an outer ring of one of the angular ball bearings on the target side is inserted into the opening side of the fixed part. The other angular contact ball bearing is fitted into the fixed bushing and fixed to the fixed part via the fixed bushing by being pressed in the axial direction by a bearing retainer screwed onto the outer periphery of the opening side of the fixed part. The outer ring is fitted into a slide bushing slidably provided inside the fixing part, and is biased by a preload spring disposed between the fixing bushes and the slide bushes. Features a rotating anode X-ray tube.
