Abstract: A turbo machine according to present disclosure includes a rotating shaft, a first impeller, a first fluid bearing, a first holding member, a first lubricating liquid casing, a first supplying passage, and a first squeeze film damper. The first fluid bearing rotatably supports the first taper portion and the first cylindrical portion. The first fluid bearing is attached to the first holding member. The first lubricating liquid casing forms a first storing space. The first supplying passage is a passage through which a lubricating liquid is supplied to the first storing space. The first squeeze film damper is a space located between the first fluid bearing and the first holding member. The first squeeze film damper communicates with the first supplying passage.

Abstract: A turbo machine according to the present disclosure includes a rotating shaft, an impeller, a first bearing, and a first supply passage. The rotating shaft includes a first taper portion and a first cylindrical portion. The first bearing includes a first taper support surface and a first cylindrical portion support surface, the first taper support surface including a first taper hole forming surface and rotatably supporting the first taper portion, the first cylindrical portion support surface rotatably supporting the first cylindrical portion. The first supply passage is open to a space formed between the first cylindrical portion and first cylindrical portion support surface. An inclination angle of the first taper hole forming surface with respect to the axial direction of the first bearing is greater than an inclination angle of an outer surface of the first taper portion with respect to the axial direction of the rotating shaft.
