In a turbo, pump according to the present invention, blades 3e and a shroud 3f are continuously formed with a boss 3c of a turbine wheel 3, a meridian plane configuration of the shroud 3f is formed as an concave arcing rotatable surface. A boss shroud 3f1 is formed substantially parallel to the axis of rotation O. A portion 3e2 of a blade outlet edge 3e1 is smoothly continuous to the boss shroud 3f1 and largely projects downstream. A portion 3e3 of the blade outlet edge 3e1 is formed substantially perpendicular to the axis of rotation O. The blade outlet...
