A supercharger that comprises a drain oil path 50d and a drain oil space 120. The drain oil path 50d is formed in a radial bearing support part 50. One end of the drain oil path 50d opens at a surface of the radial bearing support part 50 that is opposite a compressor-side thrust ring (a thrust bearing) 63 and/or a surface of the radial bearing support part 50 that is opposite a thrust collar (a borne part) 65, and the other end opens at a lower surface of the radial bearing support part 50.
