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.
