ル配線の保守をしなければならないという欠点が
あつた。 The rotary cable processing mechanism of the irradiation head of a conventional radiation therapy apparatus is located above the irradiation head, and the wiring cable is wound several times (so-called coiled) so as to be concentric with the irradiation head.
The bundled cables routed from inside the device main body are coiled inside the upper part of the irradiation head, and the ring of the coiled cable expands and contracts at the same time as the irradiation head rotates. The number of coiled cables is limited because the coiled cables may break, the cables may get caught inside the irradiation head, and the upper part of the irradiation head requires a compact structure. There was a drawback. Furthermore, when the coiled cable is broken or caught, the irradiation head, which is a heavy object, must be removed and the coiled cable wiring must be maintained.
本考案の目的は、このような従来の欠点を解消

る。 The purpose of the present invention is to eliminate such conventional drawbacks, prevent wiring cables from breaking or getting caught, ease restrictions on the number of cables, and eliminate the need for heavy irradiation during maintenance. It is an object of the present invention to provide a radiation therapy device that eliminates the need to remove a head portion, facilitates the design of a shield against radiation, and can be mounted compactly.

る。 A tightly wound coil spring 1 bent into a U-shape has a fixing part 2 at its tip, and a joining part 4 with the outer frame of an irradiation head part 3 at the other end of the coil spring 1.
A cable 5 whose one end is connected to the inside of the apparatus main body passes through the coil spring 1, and the other end of the cable 5 is connected to the inside of the irradiation head section 3. When the irradiation head 3 is rotated in the direction of the arrow from the state shown in FIG. 2, the coil spring 1 wraps around the outer frame of the irradiation head 3 while maintaining its U-shape, as shown in FIG. go. When the rotation of the irradiation head 3 is returned to normal, the coil spring 1 is corrected by the guide 6 that guides the cable 1 in a tangential position with the outer frame of the irradiation head 3, and the U-shaped will be returned to its original position while being retained.
