An object is to provide a floating bush bearing device with excellent oscillation stability and small bearing loss. A floating bush bearing device which rotatably supports a rotation shaft includes: a bearing housing, a floating bush rotatably disposed between the rotation shaft and an inner circumferential surface of the bearing housing, in the bearing housing, and a bush side oil supply hole which is formed through the floating bush and is capable of supplying lubricating oil between the rotation shaft and the inner circumferential surface of the floating bush, the inner circumferential surface of the floating bush has a non-circular shape so that a gap portion is formed between the rotation shaft and the inner circumferential surface of the floating bush, the gap portion having a predetermined clearance or larger regardless of relative positions of the rotation shaft and the inner circumferential surface of the floating bush, and the bush side oil supply hole communicates with the gap portion.

A surface coating film includes, a base material which is a hard material; and an oxidation-resistance coating layer containing, as a main component, a complex oxide of Li and at least Al and covering a surface of the base material. Further, a method of manufacturing a surface coated member, includes, supporting a base material which is a hard material in a hermetic container with the use of a holder arranged in the container; arranging a complex oxide forming target containing Li and at least Al, as main components, in the container; feeding oxygen into the container; and forming an oxidation-resistance coating layer that covers the base material to obtain the surface coated member by effecting electric discharge between the complex oxide forming target as an anode and the holder as a cathode.
