Abstract
Abstract An improved thrust roller bearing assembly is proposed which comprises a thrust roller bearing and an annular shim. According to this invention, the shim can be coupled with the thrust roller bearing beforehand. This simplifies the assembly of related members. Engaging means provided on the cylindrical portion of the outer race or the inner race or on the shim assures a stable coupling of the shim with the thrust roller bearing.
