Variable-capacity turbine

The object of this invention is to eliminate the quantity of exhaust gas supplied to the turbine without going through the channels between the nozzle vanes provided in a variable-capacity turbocharger. The nozzle unit (100) in the turbocharger (10) has a mounting plate (102) and a side plate (106) installed in a recession (20) provided in the housing (20) in such a way that the side plate can move in the recession, both of which are provided parallel to the turbine shaft; a pushing means (116,150) to push the side plate toward the mounting plate (102); and a limiting means (108) to limit the movement of the side plate parallel to the turbine shaft toward the mounting plate (102).
