Claims

[Claims for Utility Model Registration] (1) A cage that holds a plurality of rollers arranged in a radial direction, and at least one circle that is provided opposite to the cage and that brings the plurality of rollers into contact with each other. The thrust roller bearing has a ring-shaped race and is installed by fitting into the holding part of the casing, and a short cylindrical folded wall formed on the periphery of the race fits into this race. The holder consists of a circular spacer section that overlaps the main body of the lace, and a holder made of synthetic resin that is formed on the periphery of the spacer section and that fits into the folding wall. A thrust roller bearing unit having a short cylindrical fitting wall. (2) Utility model registration claim 1, in which the holding part is a circular recess formed in the casing, and the peripheral edge forming the fitting wall that fits into the recess is the outer peripheral edge of the holder. Thrust roller bearing unit described in . (3) Utility model registration claim No. 1 in which the holding part is a circular convex part formed on the casing, and the peripheral part forming the fitting wall that fits into the convex part is the inner peripheral part of the holder. The thrust roller bearing unit according to item 1. (4) The thrust roller bearing unit according to claim 2, wherein the holder has an outward flange-shaped portion on the outer peripheral edge of the fitting wall on the side opposite to the spacer portion. (5) The thrust roller bearing unit according to claim 3, wherein the holder has an inward flange portion on the inner peripheral edge of the fitting wall on the side opposite to the spacer portion.
