A rolling bearing includes an outer ring; an inner ring; a ring member; and a plurality of rolling elements that roll while in contact with the outer ring and the inner ring in a radial direction. The outer ring includes: an annular section whose inner surface has a rolling motion surface on which the rolling elements roll; and a projecting section that projects radially outwardly while being connected in an integrated manner with an axial end of the annular section, and that serves as a fixing section for fixing the outer ring to a certain supported-object member. The ring member is provided outside an outer surface of the annular section, and covers the outer surface around an entire circumference of the outer surface. The ring member and the outer surface partition an annular space therebetween. The rolling elements are pressed against the outer ring and the inner ring by diameter reduction of the annular section due to elastic deformation of the annular section in the radial direction, the elastic deformation being caused by pressurized fluid supplied to the annular space. |
