Abstract
A radial turbine impeller includes full blades and splitter blades arranged alternately in the rotational direction of the radial turbine impeller, the splitter blades having a shorter blade length in a fluid flow direction in the radial turbine impeller than the full blades. A throat is provided between each two of the full blades adjacent to each other in the rotational direction. A part of a downstream edge of each splitter blade on a side of a base edge which is joined to an outer peripheral surface of a hub is positioned upstream of the throat, and a part of the downstream edge of each splitter blade on a side of a tip edge which is remote from the outer peripheral surface of the hub is positioned downstream of the part of the downstream edge on the side of the base edge.
