Claims

[Scope of Claim for Utility Model Registration] (1) A metal lace that has a folded wall formed on its outer periphery and that has the entire circumference or three or more parts of the edge of the folded wall protruded inward; Formed in a circular ring,
It consists of a synthetic resin cage with a plurality of pockets for holding the rollers so that they can roll freely, and the outside diameter of this cage in its free state is equal to the maximum inner diameter of the protruding part of the edge of the folding wall. A non-separable type in which the retainer and race are inseparably connected by forming the retainer larger than the diameter of the tangent circle and allowing the outer peripheral edge of the retainer to ride over the above protruding part while the retainer is elastically deformed. Thrust roller bearing. (2) A folded wall is formed on the inner peripheral edge, and a metal lace is formed around the entire circumference or at least three parts of the edge of the folded wall to protrude outward, and is formed in a circular ring shape;
It consists of a synthetic resin cage with multiple pockets for holding the rollers so that they can roll freely, and the inner diameter of this cage in its free state is the minimum circumscribed circle of the protruding part of the edge of the folded wall. A non-separable type thrust roller in which the retainer and race are inseparably connected by forming the retainer smaller in diameter than the diameter of the retainer and allowing the inner peripheral edge of the retainer to ride over the above-mentioned protruding portion while the retainer is elastically deformed. bearing. (3) The non-separable thrust roller bearing according to claim 1 or 2, wherein a continuous slit from the outer circumferential edge to the inner circumferential edge is formed at one location of the cage formed in the shape of an annular ring made of synthetic resin.
