PROBLEM TO BE SOLVED: To provide a turbine simply formed, easily manufacturable, and easily increasing the output. SOLUTION: The blades 41 of an impeller 4 extends parallel to the rotating center X and are tilted rearward in the rotating direction. A casing member 6A has working fluid discharge ports 62 opened in inner surfaces 61 closing the space parts 42 between the blades 42, respectively, and arranged parallel to the rotating center X and jetting working fluid receiving parts 63 adjacent to the inner surfaces 61 in the circumferential direction. The working fluid discharge ports 62 discharge a working fluid radially inward toward the impeller 4 in the front in the rotating direction. The jetting working fluid receiving parts 63 allow the working fluid jetted from the space parts 42 to flow radially outward in the back in the rotating direction. When the impeller is rotated, in the first stage, the space parts 42 are closed by the inner surfaces 61 and the high-pressure working fluid is discharged from the working fluid discharge ports 62, and in the second stage, the high-pressure working fluid is jetted from the space parts 42 into the jetting working fluid receiving parts 63.
