Claims

[Scope of utility model registration request]

In an impeller in which a plurality of integrally molded elements each having a large number of blades standing upright in the axial direction of one of a disc-shaped or annular support member are connected on a common axis,
A cross flow characterized in that the plurality of elements are connected so that the diameter of the outer envelope circle at one end of the support member of the plurality of blades and the diameter of the outer envelope circle at the other end substantially match. impeller.
