Claims

[Claims for Utility Model Registration] Consisting of a linear guide rail and a moving body that moves astride the guide rail and has a generally inverted U-shaped cross section, Ball guide grooves are formed on opposing surfaces of both sides of the guide rail, ball outward paths are formed by both ball guide grooves, ball return paths are formed in leg-shaped portions on both sides of the moving body, and ball return paths are formed at the ends of the ball outward paths. and the ends of the ball return path are connected by reversing paths formed at both ends of the moving body to form a ball circulation path, and the ball rolls between the moving body and the guide rail in the ball circulation path of the moving body. In a direct-acting guide device in which a plurality of balls are enclosed and each ball is held in a retainer, the retainer is formed by bending a single wire into a loop shape. A linear guide device in which both ends of a loop-shaped wire holder are attached to both ends of a movable body, and two straight parts of the loop-shaped wire holder hold the ball on the ball's outward path.
