Abstract
A variable nozzle turbocharger 1 comprising: nozzle rings 21, 22 that define a scroll flow path 23; a variable nozzle 30 arranged in the scroll flow path; and a nozzle shaft 40. In the variable nozzle turbocharger having the nozzle shaft inserted through a nozzle shaft hole 60 provided in the nozzle rings, the nozzle shaft hole has: a pivot hole section 61 that pivots the nozzle shaft and a large-diameter hole section 62 provided in an end section of the nozzle shaft hole, on the scroll flow path side, and having a larger diameter than the pivot hole section 61. The variable nozzle turbocharger comprises a seal member 50 fitted to the nozzle shaft, housed in the large-diameter hole section, and sealing a gap between an inner circumferential surface 64 of the pivot hole section and the outer circumferential surface 43 of the nozzle shaft facing this inner circumferential surface.
