Abstract: The bearing device 4 is press-fitted between the inside surface of the axis insertion hole of a steering column and the outside surface of a steering axis inserted into the axis insertion hole so as to support the steering axis. The bearing device 4 comprises a roller bearing arranged on the outside surface of the steering axis and a spacer ring arranged between the outside surface of the roller bearing and the inside surface of the axis insertion hole. The spacer ring comprises a wall thickness holding unit for holding the thickness of its wall in the radius direction and a thickness reduction unit which is provided on at least one site of the inside and outside surfaces and its end in the vicinity of the wall thickness holding unit and which reduces the thickness of the wall to facilitate deformation of the spacer ring.

Abstract: A cage of a roller bearing including a plurality of pockets formed by punching from the outside, each storing a roller, in the circumferential direction of a barrel, which comprises a first projection for preventing the roller from being disassembled to the outside of the barrel and a second projection for preventing the roller from being disassembled to the inside of the barrel. The first projection is provided at a thin portion of the barrel which is formed between the brims of the pocket. The second projection is provided at a thick portion of the barrel in the axial direction by knurling.
