Summary:There is disclosed a compressor which stably supplies oil to a sliding portion. The compressor includes an ejector oil pump which sucks the oil from an oil reservoir in the bottom part of a sealed container to an oil passage formed in a rotary shaft, and the ejector oil pump includes an oil suction pipe having one end connected to the oil passage and the other end which opens in the oil reservoir, and an ejector pipe having one end which communicates with the discharge side of a compression mechanism portion and the other end inserted into the opening of the other end of the oil suction pipe to open. The inner diameter of the other end of the oil suction pipe is larger than the outer diameter of the other end of the ejector pipe so that a gap for oil suction is constituted between both the pipes, and the other end of the oil suction pipe is provided with first and second dowel portions as positioning portions which position the other end of the ejector pipe.
