Abstract
A rolling bearing apparatus is provided that rotatably supports a cam shaft in a cylinder head of an engine. The rolling bearing apparatus includes a plurality of rolling elements; a cage that positions the rolling elements so as to be spaced at regular intervals from each other in a circumferential direction and that retains the rolling elements in a freely rotatable manner; a shell-type outer ring configured to receive the rolling elements and the cage and having a raceway surface of the rolling elements at an inner side thereof; and an outer ring fastening member formed of a material having almost the same thermal expansion coefficient as the shell-type outer ring and having a press-fit portion press-fitted to the shell-type outer ring.
