Abstract:
1. A method of manufacturing a rolling bearing apparatus comprising: a first pressing step of fitting an inner face of an inner race of a first rolling bearing to an outer face of a first member in a pressed state; a second pressing step of fitting an inner face of an inner race of a second rolling bearing to a protruding fitting portion of the outer face of the first member in a pressed state at a position spaced from the first rolling bearing in an axial direction; a pre-loading step of pressing the inner races of the first rolling bearing and the second rolling bearing towards each other in the axial direction with a second member sandwiched between outer races of the first rolling bearing and the second rolling bearing; and a first welding step of welding at least a portion of a peripheral portion of the inner race of the second rolling bearing in the axial direction pressed in the pre-loading step to the outer face of the first member through irradiation with laser light, wherein the position of the fitting of the inner face of the inner race of the second rolling bearing to the protruding fitting portion of the outer face of the first member is a position at or close to the peripheral portion.
