PROBLEM TO BE SOLVED: To provide a mobile radiation generator capable of extending a horizontal range of an X-ray irradiation part 15 without complicating the structure of an arm part 17.SOLUTION: A truck part 14 includes front wheels 36F and rear wheels 36R. An arm part 17 is fitted with an X-ray irradiation part 15 at a free end thereof. A second support part 18B supports the arm part 17 at an upper end so as to freely rotate about a rotation axis AX2. A body part 16 mounted on the truck part 14 is fitted with a second support part 18B that is inclined with respect to the front of the truck part 14, where an inclination angle α is fixed.SELECTED DRAWING: Figure 46
