ABSTRACT:
In a linear motion machine in which a number of rolling elements 8 are interposed between a linearly extending guide shaft 1 and a moving body 2 linearly moved while being guided by the guide shaft 1, and the elements 8 circulate along element rolling grooves 5 in the moving body 2 while rolling within the grooves 5, a lubricant supply member 14 made of lubricant-contained polymer is located near a load-receiving areal part of the element rolling grooves 5. The lubricant is oozed out of the lubricant supply member 14 and automatically supplied to the element rolling grooves 5 and the elements 8. A stable lubrication of the machine is ensured for a long time.
