PROBLEM TO BE SOLVED: To provide a movable X-rays apparatus wherein a counter wt. such as iron corresponding to wt. of a holding part holding an X-rays tube can be equipped in the hollow part of a support by making thickness and height of the support smaller. SOLUTION: A revolving support 3 is vertically provided on a movable truck 1 and a counter wt. 8 connected with the holding part of an X-rays tube 10 movable in the up and down direction along this support 3 with a wire 9 is hung movably up and down in the support 3. The X-rays tube 10 is rotated in the horizontal plane by a support revolving part provided on the movable truck 1 and constituted of a bearing part 2 and a rotating shaft 4 with a hollow part 5. In addition a projected part 12 entering into the hollow part 5 is provided on the lower part of the counter wt. 8 in the support 3 and when the X-ray tube holding part is elevated to the uppermost level, the counter wt. 8 and the projected part 12 are lowered to the lowermost level on the contrary. In this case, by entering the projected part 12 provided on the lower part of the counter wt. into the hollow part 5 of the support revolving part, the vol. of the hollow part 5 can be utilized as the vol. of the counter wt.
