Abstract
A rotary machine includes a rotor having a cylindrical shape and having a main oil feed hole through which lubricating oil passes and that is provided in an axial direction and a slide bearing provided outward in a radial direction with a gap between the rotor and the slide bearing and configured to hold the rotor so that the rotor rotates around an axis. The rotor is provided with a branch oil feed hole through which the gap and the main oil feed hole communicate with each other and through which the lubricating oil passes. A foreign matter separating portion configured to separate foreign matter from the lubricating oil is provided further backward in a direction of rotation of the rotor than the branch oil feed hole.
