In a hydrodynamic thrust gas bearing comprising a wave-shaped bump foil, the bump foil is formed so that its height gradually increases from the leading edge side to the trailing edge side, and from this halfway position to the rear edge. 1. A dynamic pressure type thrust gas bearing, characterized in that a rigid outer ring pad is formed to be gradually lowered to an edge position, and a rigid outer ring pad having a substantially convex bearing surface is disposed on the bump foil. +2) The hydrodynamic thrust gas bearing according to claim 1, wherein a pedestal is fixed to the base plate so as to be located between the base plate and the bump foil. (3) The dynamic pressure type thrust gas according to claim 1 or 2 of the utility model registration, which is formed so that the height of the outer circumference side of the bump foil is slightly larger than the height of the inner circumference side. bearing. (4) The hydrodynamic thrust gas according to claim 1, 2, or 3, wherein the bearing surface of the bearing pad is coated with a ceramic coating. bearing.
