Abstract
An X-ray tube of the rotary anode type including lubricant passages or lubricant housing recesses formed opening at those areas of a fixed or rotary structure where spiral grooves of slide bearings are present so as to allow lubricant to be more reliably supplied to these grooves-provided areas. Even when the rotary structure starts its rotation or it is being rotated, therefore, the liquid metal lubricant can be more reliably interposed between those faces of the fixed and rotary structures on which the slide bearings are formed. This can prevent the bearings from being damaged and the operation of these bearings can be kept more stable.
