The purpose of the present invention is to prevent the risk when the wire-rope that is hanging an X-ray irradiation element including an X-ray tube breaks.The X-ray imaging apparatus to solve the above problem comprises a wire-ropes 17, 18 that hang and support an X-ray irradiation element 5 and have a different fatigue strength each other, wherein the different between the fatigue progressions of the wire-ropes 17, 18 takes place, the wire-rope 17 or the wire-rope 18 having a weaker fatigue strength breaks first and both wire-ropes 17, 18 never break simultaneously.
