ドベアリング。[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 to the outer periphery of a cylindrical or cylindrical inner member by a pair of communicating grooves. 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. The portion of each of these grooves on the outer circumferential side of the inner member from the center of the ball is formed into a narrow opening with a width smaller than the outer diameter of the ball, and a part of the narrow opening of the load ball groove is provided with a cut for inserting the ball. A slide bearing characterized by having a notch formed therein.
