Claims

[Scope of utility model registration request]

In a split type resin composite impeller in which a hollow cylindrical shaft of a full-blade impeller is inserted into a corresponding hole of a half-blade impeller and connected, a plurality of slits extending in the axial direction are provided around the hollow cylindrical shaft. A radius that is formed to be elastically deformable and that, when the hollow cylindrical shaft is inserted into a hole corresponding to a half-blade impeller, engages with the half-blade impeller to prevent the shaft from falling out of the hole. A split resin complex impeller characterized in that an engaging element protruding outward in the direction is provided near the tip of the shaft portion.
