。[Claims for Utility Model Registration] (1) Approximately 90 internal angles along the circumferential direction on the outer peripheral surface side
an inner ring 1 in which a V-shaped groove 5 of approximately 90 degrees is formed, and a V-shaped groove 6 with an inner angle of approximately 90 degrees facing the V-shaped groove 5 is formed along the circumferential direction on the inner peripheral surface side. The inclination directions intersect alternately between the outer ring 2 and the opposing V-shaped grooves 5 and 6, and the projected center line obtained by projecting a straight line passing through the axis onto the rotation plane of the inner and outer rings is In a swing bearing consisting of a large number of rollers 3 arranged so as to face the center 0 of the inner and outer rings 1 and 2, and a spacer retainer 7 that is interposed between mutually adjacent rollers 3 and holds the rollers 3, the spacer The retainer 7 is formed with curved grooves 8 and 9 on both left and right side surfaces thereof, into which the rollers 3 adjacent to each other are rotatably fitted, and these curved grooves 8 and 9 have a longitudinal center 10 as their apex. A swing bearing characterized in that inclined contact surfaces 8a, 8b, 9a, and 9b are formed that are inclined at an angle of 1/2 of the angle 2θ formed by the projected center lines of the rollers 3 adjacent to each other. (2) The slewing bearing according to claim 1, wherein an oil sump through hole 11 is formed between the curved grooves 8 and 9 on both side surfaces of the spacer retainer 7.
