<P>PROBLEM TO BE SOLVED: To simplify structure, reduce the number of parts, suppress manufacturing cost, and improve maintainability. <P>SOLUTION: A variable capacity turbine includes: a plurality of nozzle blades 31 disposed with equal pitches along the circumferential direction in a fluid inlet passage 24; a nozzle baseplate 32 which forms one wall surface of the fluid inlet passage 24 and is provided with an end surface 32a connected with an end surface 31a on the one side of the nozzle blade 31; a back plate 34 which is opposite to the nozzle baseplate 32, forms the other wall surface of the fluid inlet passage 24, and is provided with an end surface 34a formed with recesses 34b each containing an end surface 31b on the other side of the nozzle blade 31; and a drive means 45 which advances/retracts the nozzle baseplate 32 coupled with the nozzle blade 31 along the rotation axis direction so as to vary the fluid passage cross-section of the fluid inlet passage 24. <P>COPYRIGHT: (C)2012,JPO&INPIT |
