摘要： A rotary positive pole type X−ray tube, wherein a positive pole target (22) is rotatably supported by a rotating mechanism (25) having a rotating body (23) and a fixed body (28), a fitted portion between the rotating body (23) and the fixed body (28) is formed of bearing areas (L1) to (L4) having dynamic sliding bearings and a non−bearing area (L5) having a clearance between the rotating body (23) and the fixed body (28) larger than that in the bearing areas (L1) to (L4), and the rotating body facing the non−bearing area is positioned where a time for heat transfer from the positive pole target (22) is shorter than that from the rotating body facing the bearing areas, whereby the characteristics of heat radiation from the positive pole target (22) can be increased, and a stable bearing operation can be maintained.
