Claims

[Claims for Utility Model Registration] (1) A roller bearing that is attached to the end of the shaft with a cylindrical shaft as an inner ring, and a roller bearing that is attached to the outer ring end of the roller bearing and is slidably inserted into the inner hole of the cylindrical shaft. a roller bearing device having a seal that forms a sealed portion with an outer circumferential surface of a shaft, the seal having a fixing portion to the outer ring end on the outer circumference, and a seal on the inner circumference in one direction in the axial direction; A roller bearing device comprising: an annular plate having a protruding cylindrical portion; and an elastic body attached to the annular plate to form a sealing portion between the annular plate and the outer peripheral surface of the shaft. (2) In claim (1), at least one axial end surface of the outer ring is provided with an annular step portion for attaching a seal, and the step bottom of the annular step portion extends from the outer ring end surface side to the inner side of the outer ring. The seal is formed in a tapered shape that gradually becomes larger in diameter toward the seal, and the outer peripheral edge of the annular plate of the seal is bitten into the tapered step bottom portion of the annular step portion by plastic deformation due to caulking. roller bearing device.
