Provided are a stator blade assembly advantageous for improving the evacuation performance by shortening the evacuation time, and an exhaust pump provided with such a stator blade assembly. Inner and outer stator blade bases 14A, 14B of a plurality of stator blades 14 are supported by frames F1, F2. A projecting portion T protruding from the frame F1 supporting the inner stator blade base 14A, or from the frame F2 supporting the outer stator blade base 14B, or from both of the frames F1, F2 is provided in a gap in the vicinity of the inner or outer stator blade base 14A, 14B between one of the supported stator blades 14 (14-1) and the stator blade 14 (14-2) transversely adjacent thereto. |
