In the conventional mobile X-ray apparatus, the front part of the lower wheel of the trolley is formed into an eave shape so as to avoid an obstacle in front of the trolley so that the wheel does not step on the cable. However, such a structure is not so effective because the eaves of the frame may bite the cable in some cases. Therefore, when moving the mobile X-ray apparatus, the operator usually has to remove the cable in many cases. Further, even in a device provided with a means for avoiding the above-mentioned cable, the operator needs to evacuate the means each time when getting over a step, which may increase the burden on the operator. . Further, if the operator tries to move the device without noticing the step during the movement, the means may be damaged.

The present invention has been made by paying attention to the above-mentioned problems, and it is possible to eliminate an operator from stepping on the cable only by moving the apparatus in the traveling direction, and there is a step in the middle of the movement. It is an object of the present invention to provide a mobile X-ray apparatus which can smoothly overcome a step even if it exists.
