PROBLEM TO BE SOLVED: To provide a compressor appropriately supplying lubricating oil to sliding portions of a shaft and bearing portions. SOLUTION: The axial lower end of the shaft 25 transmitting rotational driving force to a compression mechanism section 10 is rotatably supported by the first bearing portion 29, and also the axial upper end of the shaft 25 is rotatably supported by the second bearing portion 27. Further, a main oil filler passage 25a extending in the axial direction and first and second auxiliary oil filler passages 25b, 25c extending in the radial direction are formed inside of the shaft 25, and a pipe member 50 leading oil to the vicinity of the inlet of the second auxiliary oil filler passage 25c is arranged inside of the main oil filler passage 25a. Thereby, it is possible to supply the oil to the sliding portion of the shaft 25 and the second bearing portion 27 arranged on a side higher than the first bearing portion 29, and it is possible to supply the oil also to the sliding portion of the shaft 25 and the first bearing portion 29 by gravity action.
