摘要： A thrust bearing device 40A is constituted by a turbine-side thrust collar 42 and a compressor-side thrust collar 44 that are fixed to a rotary shaft 12; and a thrust bearing (46) that is arranged between the thrust collars. The thrust bearing 46 is provided with an oil passage 48 that supplies lubricating oil r to sliding-contact surfaces formed between the thrust bearing 46 and the thrust collars 42 and 44. The outsides of the thrust collars 42 and 44 in a radial direction incline toward the thrust bearing 46 side. A gap c between the sliding-contact surfaces is narrowed as the gap goes outward in the radial direction, and establishes a basic region gap (c1) > an outer peripheral end gap (c2). The lubricating oil outflow resistance of a radial outer region of the gap c becomes larger than that of a radial inner region. Therefore, the lubricating oil r can be kept from flowing out from a radial outer outlet.

摘要： When changing a nozzle blade angle by rotating a drive ring, a contact load generated between an inner circumferential surface of the drive ring and an outer circumferential surface of a mount can be reduced, allowing the drive ring to rotate smoothly and reducing the amount of wear and a driving force. It is also possible to reduce an impact force, such as engine vibrations, generated at the drive ring when an external force acts, reducing the risk of damage. A plurality of notches (19) are provided at an inner rim of the drive ring (14), and, among inner circumferential surfaces (14a, 14b, 14c, 14d, 14e, 14f, 14g, and 14h) located between the notches (19), when a driving force for rotating the drive ring (14) is applied, the inner diameters of the inner circumferential surfaces (14e, 14f, 14g, and 14h) where the contact load with the outer circumferential surface of a mount becomes large are made larger than the outer diameter of the outer circumferential surface.
