PROBLEM TO BE SOLVED: To provide a turbine rotor, a turbine unit and a turbocharger, capable of making the difference between pressure occurring on the positive pressure surface of a blade and pressure occurring on the negative pressure surface thereof small on the downstream side in a flow direction of fluid in a blade part.SOLUTION: The blade thickness on an upstream end part 26C side in a turbine blade 26 is thicker than the blade thickness on a downstream end part 26 D side in the turbine blade 26. Further, the flow passage cross sectional area of an inflow port 62A is larger than those of other portions. Consequently, the difference between pressure occurring on a positive pressure surface 60 of the turbine 26 and pressure occurring on a negative pressure surface 58 thereof is made small. |
