ABSTRACT:
In the present invention, a partition wall which partitions a discharge port and a suction port provided on a static passage, in the rotating direction, has a discharge side shape which is identical with the shape of blades, and has a positional relationship in which the partition wall does not overlap with the discharge port in view of such a fact that the pressure variation on the suction side is higher than that of the discharge side, and noise on the suction side is dominant.
