The casing and the partition wall are integrally formed. The casing has a circular opening through which the shaft is inserted into the low-pressure chamber and another circular opening which is sealingly closed by a lid having high-rigidity. The casing also has an inlet port through which fluid is introduced into the low-pressure chamber and an outlet port through which the pressurized fluid is discharged from the high-pressure chamber.
