PURPOSE: To get rid of force acting in the axial direction of a turbine by installing plural pieces of symmetrical blade profile turbine blades extending as separated in parallel with an axis of rotation of a rotor hub.
CONSTITUTION: One end of plural pieces of symmetrical blade profile turbine blades in the same form and size is tightly attached to a peripheral edge at the one end side of a disklike rotor hub 6 symmetrically as to rotation axis X. Tangential force sinα acting on each turbine blade comes to an output shaft moment. With this moment, such force that is expressed with Fcosα in the tangential direction is received, but if looking at a radial turbine as a whole, the sum total of these value of force comes to zero in substance when taking a fact into consideration that these turbine blades 5 are clamped to the rotor hub 6 at regular intervals.
