。[Claims for Utility Model Registration] It has a track rail that has a trapezoidal cross section and extends in the shape of a rail, with ball rolling grooves formed on both inclined sides, and a recess with a trapezoidal cross section that fits the track rail. Ball transfer grooves are formed on the slanted inner surfaces of both hanging parts, respectively, facing the ball rolling grooves, and bolt holes for mounting a sliding base are provided in the upper part of both hanging parts. A ball circulation hole is formed on each side, and both pole transfer grooves and the ball circulation hole include a sliding table connected to the ball circulation path through a circulation path formed in the end cap, and the ball circulation hole is accommodated in the ball rolling groove. In a linear guide device in which a sliding table moves in a straight line by rolling a large number of balls, the ball circulation hole is formed on the side of both ball transfer grooves, and the end cap is provided with balls. An upwardly convex circulation path is formed to scoop up the ball at right angles to the slanted outer surface, gently change the direction of the ball, and guide the ball to the ball circulation hole. A linear guide device characterized by avoiding interference with holes.
