PROBLEM TO BE SOLVED: To provide a structure capable of suppressing vibration of a shaft in a self-priming pump.SOLUTION: A self-priming pump 1A has a first casing 21A, a second casing 22A, and a third casing 23A. A rear-side end of a shaft 26A is fixed to the first casing. A front-side end of the shaft is fixed to a shaft support part 50A provided to the second casing. In this self-priming pump, the second casing and the third casing are fixed by a fixing means 27A. Vibration of the second casing is thereby suppressed. As a result, vibration of the shaft fixed to the shaft support part of the second casing is also suppressed. |
