Abstract
A plurality of flat plates are laterally disposed at an outer circumference of a hub and auxiliary vanes are disposed in parallel to at least side edges of each of said flat plates while being spaced apart from the side edges. Accordingly, an occurrence of eddy flows can be restricted, a peeling-off eddy flow can be reduced, agitating and mixing of gas-liquid can be made efficient without producing any damage to microorganisms or the lie and an agitating efficiency can be improved with a simple structure.
