PROBLEM TO BE SOLVED: To provide an oil feeder capable of feeding oil with a desired oil quality despite the fact that the oil feeder is formed rather simple at a low cost. SOLUTION: This oil feeder comprises lubrication points allowed to receive lubricating oil and hydraulic units 11 and 12 allowed to receive hydraulic equipment oil, and an oil tank 5 used in common for lubrication oil and hydraulic equipment oil. A feed line 6 from the oil tank is branched at a branch point 13 into a lubricating oil branch pipe 6a and a hydraulic equipment oil branch pipe 6b. A filter device 26 disposed midway of the feed conduit 6 and installed in the upstream of the branch point 13 is installed exclusively to the filter device, and the device also has a plurality of filter units 28 and 29 with different mesh widths matching quality requested for the hydraulic equipment oil. Thus a simple and compact structure can be realized.
