Claims

[Claims for Utility Model Registration] (1) A cage that holds a plurality of rollers arranged in a radial direction, and a ring-shaped inner and outer ring that is provided opposite to the cage and that brings the plurality of rollers into contact with each other. A thrust roller bearing, which is installed by fitting into the holding part of the casing, is connected to this race by engagement with the peripheral edge of the race. This holder consists of a circular spacer part which is overlapped with the race, and a holder formed on the periphery of the spacer part, and the holder is formed on the periphery of the holder.
A thrust roller bearing unit having a short cylindrical retaining wall that inseparably connects a retainer and a retainer through non-contact engagement during use. (2) The thrust roller according to claim 1 of the utility model registration claim, wherein the retainer has an inward or outward flange-shaped portion on the inner peripheral edge or outer peripheral edge of the retaining wall on the side opposite to the spacer portion. bearing unit.
