(57) Disclosed herein is an impeller including: an upper plate formed integrally with upper blades; and a lower plate formed integrally with lower blades each including a coupling groove formed in an inner side thereof so that the upper blades are coupled thereto, the coupling groove corresponding to the upper blade, wherein the upper plate and the lower plate are coupled to each other so that the upper blades are fitting-coupled to the coupling grooves of the lower blades. Each of the upper and lower blades is formed on the upper and lower plates configuring the impeller, and a coupling structure between the upper and lower blades is integrated, thereby making it possible to improve rigidity of the impeller.
