PROBLEM TO BE SOLVED: To feed a lubricant to three systems or more systems of conduit lines separately from a single pump, to enhance a freedom degree of lubricant feeding and versatility, to facilitate the system, and to realize cost reduction. SOLUTION: This device is provided with the single pump 10 for feeding the lubricant stored in a lubricant storage part 20, and a plurality of switch valves 30 and 50 sequentially and continuously connected to the pump 10 and switched so as to separately feed the lubricant to the plurality of conduit lines P1, P2 and P3 having the different systems. The switch valve 30 upper than the lowermost switch valve 50 is switched so as to connect the pump 10 and the conduit line P1, the lowermost switch valve 50 is switched so as to connect the pump 10 and the conduit line P2 and is switched so as to connect the pump 10 and the conduit line P3.
