陽極Ｘ線管。[Claims for Utility Model Registration] 1. Consists of an anode part and a cathode part that are vacuum-enclosed in one envelope, and the anode part has a target that collides with accelerated and focused electrons from the cathode part, and a target that rotates the target. In a rotating anode X-ray tube that has a rotor that is directly connected to the rotor, the cathode part has three parts: a focusing electrode that focuses thermionic electrons, a holding part for the focusing electrode, and a support part that supports the holding part through an envelope. A rotating anode X-ray tube, characterized in that it comprises an integral member consisting of a rotary anode X-ray tube. 2 Consists of an anode part and a cathode part that are vacuum-enclosed in a single envelope, and the anode part has a target that collides with accelerated and focused electrons from the cathode part, and a rotor that is directly connected to the target to rotate it. In the rotating anode X-ray tube, the cathode part is an integral member consisting of a focusing electrode that focuses thermoelectrons, a holding part for the focusing electrode, and a supporting part that supports the holding part through an envelope. A rotating anode X-ray tube, characterized in that the focusing electrode is fixed by the integral member.
