Claims

[Scope of Claim for Utility Model Registration] (1) A fixing device for a bearing in a caster that fixes a bearing interposed between an axle housing and an axle, which comprises a pair of segments made of synthetic resin; Each segment includes a cylindrical part that can be fitted between the axle housing and the bearing fitting, and a hole formed at one end of the cylindrical part that is smaller than the outer diameter of the bearing fitting and has an outer diameter larger than the inner diameter of the axle housing. 1. A fixing device for a bearing in a caster, comprising a flange having a diameter, and a locking portion formed at the other end of the cylindrical portion and capable of being locked to each other as the segments approach each other in the axial direction. (2) The fixing device for a bearing in a caster according to claim 1, wherein a positioning rib that can be engaged with an axial positioning groove provided on the inner circumference of the axle housing is provided on the outer periphery of the cylindrical portion. (3) The device for fixing a bearing in a caster according to claim 1 or 2, wherein the flange and the cylinder portion are provided with axial slits.
