PURPOSE:To ensure support by integrally providing, on the outer circumferential surface of a horizontally fixed outer casing spacer-projected pieces for mounting an inner casing and the outer casing on almost the same axis. CONSTITUTION:An inner casing 7 incorporating a pump part 10 is mounted on the same axis with an outer casing 3, and a spacer-projected pieces 14 are integrally mounted on the outer circumferential surface of the inner casing 7 at the side of a motor part 8. The spacer-projected pieces 14 are installed almost near the center of gravity to be integrally prepared at the side of the motor part 8 of an inlet port 9, and extended in three directions, that is, in the downward and sideways directions. Accordingly, support can be secured.
