A bearing apparatus for including a camshaft, a plurality of cam blocks disposed in an axial direction on the camshaft, a housing member including an arc concave portion, a cap member which is fixed to the housing and includes an arc concave portion, a roller bearing interposed between the arc concave portion of the housing member and the arc concave portion of the cap member so as to rotatably support the camshaft, and annular first and second control rings which are separately provided from the camshaft, and are press-fitted and fixed to an outer surface of the camshaft at opposite side portions of the roller bearing in the axial direction. Surfaces of the first and second rings that face each other are formed as slide surfaces, and the slide surfaces come in contact with opposite side surfaces of at least one of the housing member and the cap member to receive an axial load.
