Claims

[Scope of utility model registration request]

The sleeve has an extended guide rail with ball rolling grooves in the axial direction on both sides, and a ball rolling groove opposite to the ball rolling groove of the guide rail on the side surface of the sleeve. A slider body having a ball return passage forming a through hole parallel to the ball rolling groove and spanning over the guide rail, and a ball rolling groove of the slider body attached to both ends of the slider body. an end cap having a semi-circular curved path that communicates with the ball return passage; and an end cap that is fitted between the ball rolling groove of the guide rail and the ball rolling groove of the slider body, and the curved path of the end cap. and a large number of balls that loosely fit into the ball return passage of the slider body, wherein the slider body has a notch that cuts out the ball rolling groove and the ball return passage of the body at an intermediate portion thereof. A linear guide device characterized in that a double-sided end cap having a semi-circular curved path formed on both sides back to back is fixed to the notch, and the ball circulation path is divided into a plurality of parts.
