Claims

[Claims for Utility Model Registration] (1) A container that stores a plurality of balls, which has a shaft insertion hole approximately in the center into which a pivot shaft can be inserted, and which is connected to a circumferential end surface of the container. A pivot type bearing comprising a flange plate, wherein the flange plate has a thickness greater than the vessel wall of the container and has a cutout window or groove formed along a circumferential portion thereof, and the container is A pivot type bearing characterized in that it has a circumferential end surface portion that is fitted into a notch window or groove of the flange plate. (2) The pivot type bearing according to claim 1, wherein the flange plate is made of a synthetic resin material with self-lubricating properties. (3) The pivot type bearing according to claim 1, wherein the flange plate is made of a synthetic resin material with a small coefficient of friction. (4) The pivot type bearing according to claim (1), wherein a film having self-lubricating properties is formed in the shaft insertion hole of the flange plate. (5) The pivot type bearing according to claim 1, wherein a coating made of a material having a small coefficient of friction is formed in the shaft insertion hole of the flange plate. (6) The pivot type bearing according to claim (1), wherein a plurality of cutout windows of the flange plate are formed on the same circumference. (7) The pivot type bearing according to claim (1), wherein a plurality of grooves of the flange plate are formed on the same circumference. (8) The pivot type bearing according to claim (1), wherein the groove of the flange plate is formed in an annular shape. (9) Claim (1) wherein the flange plate comprises an annular outer member and an inner member that fits into the annular outer part.
Pivot type bearings as described in . (10) The pivot type bearing according to claim (1), wherein a minute protrusion is formed on the inner wall of the cutout window of the flange plate.
