PROBLEM TO BE SOLVED: To require no oil passage for carrying out a lubrication of a sealing means for partitioning a high discharge pressure area at the inside of a compressor and a low pressure area at the inside of the compressor at a surface of a rotation member. SOLUTION: In a lip seal 37 interposed between a center housing 12 and a periphery surface of a rotation shaft 14, a removal thereof from an insertion hole 121 is inhibited by a snap ring 38. A support part 122, i.e., a forming part of the insertion hole 121 for supporting the lip seal 37 is put out in a motor housing 13. An outlet 324 of a discharge passage 32 is directed to a tip end of the snap ring 38 and the support part 122.
