To provide an apparatus and method for evaluating bearing fatigue life of lubricant, capable of miniaturizing the structure of a pressure mechanism and enhancing evaluation accuracy.

An angular ball bearing mechanism 2 enabling the relative rotation of an outer wheel member 21 and an inner wheel member 22, both of which are immersed in lubricant and opposed to each other, through spherical bodies 23, the pressure mechanism 4 for pressing the outer wheel member 21 and the inner wheel member 22 in a mutually approaching direction and a rotary mechanism 3 for rotating the inner wheel member 22 with respect to the outer wheel member 21 are provided. The protruded spherical surfaces of the spherical bodies 23 come into contact with the rolling part 22A of the inner wheel member 22 in a protruded state (spot like state) and the pressing force from the pressure mechanism 4 is concentrated to one place of the rolling part 22a and each of the spherical bodies 23.
