直動形ガイド装置。[Claims for Utility Model Registration] 1. Consists of a linear guide rail and an inverted U-shaped moving body that moves astride the guide rail, with leg-like structures on both sides of the guide rail and on both sides of the moving body. Ball guide grooves are formed on the surfaces facing both sides of the guide rail in the part, ball outward paths are formed by both ball guide grooves, and ball return paths are formed in the leg-shaped parts on both sides of the moving body, and the ball outward path is formed. The end portion and the end portion of the ball return path are connected by a reversing path formed at both ends of the moving body to form a ball circulation path. In a linear guide device in which a plurality of moving balls are enclosed and the balls on each ball's outward path are held by a wire holder, the wire holder prevents the balls from contacting the groove surfaces of both ball guide grooves on the ball's outward path. A direct-acting guide device that is placed in a space between the guide rail and the moving body at a position sandwiched between the dots. 2. The linear guide device according to claim 1, wherein the wire holder has an irregular cross section and is formed with a cylindrical ball guide surface.
