PROBLEM TO BE SOLVED: To avoid disadvantages such as encroachment on a usable rotational frequency region, degradation of efficiency, noise, an increase in load to a material, and functional disorder of a structure in the case resonance occurs, occurring by vibration of turbine blades. SOLUTION: A fluid mechanism for the turbocharger having a guide device including a housing (1) defining a flow passage of a fluid flowing through the fluid mechanism, an impeller hub (2) rotatably supported in the housing (1), a plurality of turbine blades (3) provided to the hub (2) for changing the flow direction of the fluid, and guide blades (4) for changing the flow direction of the fluid, and an interference generating device (5) for generating interference in the flow of the fluid is proposed. The interference reduces vibration of the turbine blades (3) caused by the guide blades (4) by superposition. COPYRIGHT: (C)2010,JPO&INPIT
