A fixed vane-type turbocharger comprising: a bearing housing; a turbine housing with a first flow passage between the turbine housing and the bearing housing; a compressor housing with a second flow passage between the compressor housing and the bearing housing; a fixed vane assembly (15, 29) provided in at least one of the first and second flow passages (9, 28), and comprising a movable member (11, 31) which is capable of forward and backward movement and has a first face facing a face of the bearing housing and a second face opposed to the first face, and vanes (14, 32) which are fixed to the second face of the movable member (11, 31); and a pressing means provided between the first face of the movable member (11, 31) and the face of the bearing housing, and pressing the movable member (11, 31) so that distal ends of the vanes (14, 32) are brought into pressure contact with a face of the turbine housing or a face of the compressor housing which faces the vanes (14, 32); wherein the pressing means comes into contact with the first face of the movable member (11, 31) within a range in a radial direction where the vanes (14, 32) are disposed so that the distal ends of the vanes (14,32) are brought into pressure contact with the face of the turbine housing or the face of the compressor housing within the range in the radial direction where the vanes (14,32) are disposed, characterized in that: the pressing means is a disk spring, and an outer circumferential edge of the disk spring presses against the first face of the movable member (11, 31) along a circle corresponding to the center-of-gravity positions of the vanes (14, 32). a bearing housing; a turbine housing with a first flow passage between the turbine housing and the bearing housing; a compressor housing with a second flow passage between the compressor housing and the bearing housing; a fixed vane assembly (15, 29) provided in at least one of the first and second flow passages (9, 28), and comprising a movable member (11, 31) which is capable of forward and backward movement and has a first face facing a face of the bearing housing and a second face opposed to the first face, and vanes (14, 32) which are fixed to the second face of the movable member (11, 31); and a pressing means provided between the first face of the movable member (11, 31) and the face of the bearing housing, and pressing the movable member (11, 31) so that distal ends of the vanes (14, 32) are brought into pressure contact with a face of the turbine housing or a face of the compressor housing which faces the vanes (14, 32); wherein the pressing means comes into contact with the first face of the movable member (11, 31) within a range in a radial direction where the vanes (14, 32) are disposed so that the distal ends of the vanes (14,32) are brought into pressure contact with the face of the turbine housing or the face of the compressor housing within the range in the radial direction where the vanes (14,32) are disposed, characterized in that: the pressing means is a disk spring, and an outer circumferential edge of the disk spring presses against the first face of the movable member (11, 31) along a circle corresponding to the center-of-gravity positions of the vanes (14, 32).
