PROBLEM TO BE SOLVED: To provide a lubrication management mechanism which can continuously supply lubricant to a contact portion, and facilitate automation of cleaning of the contact portion in a moving system in which a movable body is reciprocated while being in contact with an induction rail. SOLUTION: A thread groove 10A is formed on an outer wall surface, while a conduction passage 11 for fluid is arranged inside. One end of the conduction passage 11 is opened to the thread groove 10A at an aperture 12. A screw shaft 10 is rotatable around a longitudinal shaft. A tubular front of a supply pipe 30 is arranged along an inner wall of the conduction passage 11. A rotary connection part 20 seals a gap between the conduction passage 11 and the supply pipe 30. A screw nut 8 has a thread groove 8A formed with a through- hole at its inner wall surface, while the tread groove 8A being screwed with the thread groove 10A of the screw shaft 10.
