Abstract
The present invention relates to an air foil journal bearing in which air is introduced between a foil and a rotor rotating at high speed and generates pressure to support a radial load of the rotor and allow the rotor to rotate smoothly, and more particularly, to a housing fixing structure of an air foil journal bearing that improves durability against external impact or vibration by restricting an axial movement of a bump by means of two opposite ends of the bump and a top foil fixing portion.
