PROBLEM TO BE SOLVED: To provide a compressor for stably supplying an oil to a sliding part. SOLUTION: This compressor comprises an ejector oil pump 80 for sucking the oil from an oil sump 15 at the inside bottom part of a closed container 12 into an oil passage 90 formed in a rotating shaft 16. The ejector oil pump 80 comprises an oil sucking pipe 82 one end of which is connected to the oil passage 90 and the other end of which is opened into the oil sump 15 and an ejector pipe 88 one end of which is communicated with the discharge side of a first rotating compression element 32 and the other end of which is inserted into the other end opening of the oil sucking pipe 82 and opened. The inner diameter Sb of the oil sucking pipe 82 at the other end is larger than the outer diameter Sa of the ejector pipe at the other end, and gap for sucking the oil is formed therebetween. A first dowel part 71 and a second dowel part 72 are formed, as a positioning part 70 for positioning the other end of the ejector pipe 88, at the other end of the oil sucking pipe 82.
