摘要:
A foil bearing unit includes: a first foil holder formed of a single component; a radial bearing foil mounted to an inner peripheral surface of the first foil holder; a thrust bearing foil mounted to an end surface of the first foil holder; and an inner member including: a shaft portion; and a flange portion projecting radially outward from the shaft portion. The inner member is supported in a radial direction by a fluid pressure that is generated in a radial bearing gap between a bearing surface of the radial bearing foil and an outer peripheral surface of the shaft portion, and the inner member is further supported in a thrust direction by a fluid pressure that is generated in a thrust bearing gap between a bearing surface of the thrust bearing foil and one end surface of the flange portion.
