摘要： (57) [Abstract] [Purpose] The present invention is when combining a plurality of constituent members, even in a state where the tip portion of the blade 5 has been slightly reduced in the inner diameter direction by the strain in molding, the configuration of the adjacent members mutually By that allows for the positioning accuracy, it is to an object to be adapted to constitute an irregular pitch cylindrical impeller 1 having the effect of reducing low noise variation. [Configuration] components of the unequal pitch cylindrical impeller of the present invention, said in a circular plate-like support member 2 of the components 1, at a predetermined unequal pitch in the same manner as the blades 5, positioning the fitting groove 3 is provided with, and is characterized by providing the tapered protruding ring 4 in contact with the inner peripheral surface of the fitting groove 3.
