Claims

[Scope of Claim for Utility Model Registration] A loaded ball groove along the axial direction of the inner member and a deeper non-load ball groove are connected by a pair of communication grooves on the outer periphery of a cylindrical or cylindrical inner member. At least three sets of annular ball circulation paths in which a plurality of balls are stored in these grooves are provided at equal intervals in the circumferential direction, and a cylindrical outer member is disposed outside the inner member to accommodate the load ball grooves. In a slide bearing that is fitted and supported through balls located inside, the balls are housed in each groove of the ball circulation path with their centers located inside the outer periphery of the inner member. . A slide bearing characterized in that a ball fall prevention member is attached to a convex portion surrounded by the ball circulation path of the inner member.
