Abstract (en)
[origin: EP2871328A1] In a variable nozzle turbocharger, variable nozzles operate through circumferential displacement of a unison ring (12) aligned with a main plate (10) in a thickness direction thereof. A gap is formed between facing surfaces (F1, F2) of the unison ring and the main plate, and projections (41) that project from one surface (F1) out of the facing surfaces (F1, F2) toward the other surface (F2) are provided in the gap. When the unison ring is displaced in its circumferential direction, foreign substances attached to the gap between the facing surfaces (F1, F2) are scraped out from the gap by the projections.
