Abstract: PROBLEM TO BE SOLVED: To provide a thin and compact seat slide device which can freely move a seat by one action not only in the longitudinal direction but also in the lateral direction and also in the diagonal direction.
SOLUTION: Two sets of roller groups 16, 26 piled in a plurality of steps are arranged between a car body and a seat. A holder 14, 24 holds each roller 16a or 26a, its rolling axial center is arranged in parallel in each roller group 16 or 26, in the other hand the rolling axial center of first/second roller groups 16 and 26 is made orthogonal. An intermediate member 30 is arranged between the two roller groups 16 and 26, the rollers 16a and 26a are rolled on both end surfaces of the intermediate member 30.

Abstract: PROBLEM TO BE SOLVED: To provide an integrated thrust bearing wherein a bearing ring and a cage are reliably non-separable from each other even when a clearance inside the bearing in the radial direction is increased.
SOLUTION: Pawls 6 which are set to be high enough for the end faces of rollers 2 to be exposed from the front end of a collar 5a of an outer ring 5 lock the outer peripheral edge of the cage 3 provided at the front end of the collar 5a of the outer ring 5. They are formed by protruding portions protruding toward the inside at a plurality of peripheral positions of the front end of the collar 5a of the outer ring 5.

Abstract: PROBLEM TO BE SOLVED: To provide a one-piece type thrust bearing capable of securely having a ball race and a cage non-separable when the bearing inner clearance in the radial direction is large.
SOLUTION: A plurality of claws 6 projecting inward at the tip of a collar 5a of an outer ring 5 for engaging the periphery of cage 3 are formed by bending so that the projection of each claw 6 is larger than the bearing inner clearance δ in radial direction in order to securely making the inner and outer rings 4, 5 and the cage 3 non-separable even if the bearing inner clearance δ is large.
