Claims

[Scope of utility model registration request]

(1) A rotating cylinder to which an anode target is fixed, a rotating shaft coaxially fixed to the inside of this cylinder, a cylindrical anode fixing base disposed between this rotating shaft and the cylinder, and this A pair of ball bearings consisting of an inner race, an outer race, and a ball interposed between the anode fixed base and the rotating shaft, a coil spring disposed between the pair of ball bearings, and one end of the coil spring. In the rotary anode X-ray tube, the rotary anode X-ray tube includes a fixed spacer provided in contact with one of the pair of ball bearings, and a movable spacer provided in contact with the other end of the coil spring and the other end of the pair of ball bearings. A rotating anode X-ray tube characterized in that a gap exists between the outer peripheral surface of the anode fixing base and the inner surface of the anode fixing base.

(2) The movable spacer is fitted to the outer race of the ball bearing.
Rotating anode type X-ray tube as described in .

(3) The rotating anode type according to claim 1 of the utility model registration claim, wherein the gap is set to 30 μm or more.
