BEARING DEVICE FOR DRIVE WHEEL

摘要

PROBLEM TO BE SOLVED: To provide a bearing device for a drive wheel capable of accomplishing light weight/miniaturization of the device and preventing noise generated on an abutment surface of a calked part of an internal member and a shoulder of an outer coupling member over a long period of time. SOLUTION: A thrust bearing 25 having a resin covering film containing a binder resin comprising a fluorine resin and a heat-resistant resin and a metal oxide as indispensable components on a surface of a disc of metal is interposed between the shoulder part 19 of the outer coupling member 14 and an inner end surface 7a of the internal member 8.
