To provide an elevating/descending apparatus for X-ray examination, which is produced relatively inexpensively and is stable during examination which moves the center of gravity.
A disk 11 is installed on the axis 12 of an elevating/descending/ rotating apparatus, said disk 11 having an at least partially circular peripheral surface. The disk 11 is firmly fixed to the apparatus, etc., and at least a pair of rollers 21 and 22 is arranged at an immobile portion 15 and 16 of a substrate. A connecting means 25 is provided to connect the rollers 21 and 22 to the disk, so that when each roller of a first roller pair rotates simultaneously toward a different direction the disk 11 and the body of the apparatus slide vertically, and when each roller of a first roller pair rotates simultaneously toward a same direction the disk 11 and the body of the apparatus rotate a central axis 30.
