PROBLEM TO BE SOLVED: To increase, in a supercharger formed with a space for noise prevention and so forth in the inner periphery of a compressor housing, the capacity of the space while compactifying the supercharger.SOLUTION: A compressor housing 5 surrounds a compressor chamber 20 in which compressor blades 2 rotate, and is formed of an inner housing 17 and an outer housing 18, which are fitted to each other in the axial direction. A tubular part 18a of the outer housing 18 is formed with an inward-opening groove 25, and an internal space 26 opened toward the inward-opening groove 25 is formed between the inner periphery of the outer housing 18 and the outer periphery of the inner housing 17. The internal space 26 can be formed having a large capacity without increasing the outer diameter of the inner housing 17. |
