Claims

[Scope of utility model registration request]

A track rail having rolling grooves formed in the longitudinal direction on an upper surface and both side surfaces, and rolling grooves formed in the longitudinal direction on an inner circumferential surface corresponding to the rolling grooves of the track rail, and the rolling grooves. a bearing body having a ball return hole penetrating through both end faces formed in an adjacent portion separated by a predetermined distance from the bearing body; and a bearing body that is attached and fixed to both end faces of the bearing body, and that communicates the rolling groove and the ball return hole. The track rail includes a lid body having an arc-shaped ball return path, a rolling groove of the track rail, a rolling groove and a ball return hole of the bearing body, and balls arranged and held in the ball reversing path of the lid body. In a linear motion bearing in which the bearing body is slidably straddled over the bearing body through the ball, the lid body is connected to an inner lid having a rolling surface that guides the ball on the reversed inner diameter side and the reversed outer diameter of the ball. an outer cover having a rolling surface serving as a side guide; the inner cover and the outer cover are overlapped to form a ball reversal path by the rolling surfaces; and the inner cover and the outer cover are overlapped. A linear motion bearing characterized in that a part of a spigot for positioning is provided on a surface thereof by protruding the above-mentioned rolling surface for reversal.
