Claims

[Claims for Utility Model Registration] 1. Consisting of a linear guide rail and a movable body that moves astride the guide rail, the movable body has an approximately inverted U-shape in cross section and has ring-shaped leg-like parts on both left and right sides. It consists of a moving block having a ball circulation path, and a plurality of balls that circulate through each ball circulation path of the moving block and roll between the guide rails. Each ball circulation path is formed by a groove-shaped outgoing path formed so as to face the guide rail using a retainer on the guide rail side of the leg-like portions on both the left and right sides of the moving block, and an intermediate portion. A direct-acting guide device comprising a hole-shaped return path formed on the outside in the left-right direction of the forward path of the leg-shaped portion, and a reversal path formed at both front and rear ends of the moving block to connect the end of the forward path and the end of the return path. , A ball guide part constituting a part of the reversing path is formed at either the front or rear end of the intermediate portion of the moving block, and the width in the left-right direction at the outer end in the front-rear direction of the ball guide part is larger than the diameter of the ball. A direct-acting guide device characterized by being larger. 2. A guide member that is fitted into the end cap portion and forms a reversal path is integrally formed at one end of the intermediate portion of the moving block, and a ball guide portion is formed from both left and right sides of the guide member to the outside in the front and back direction. 2. The direct-acting guide device according to claim 1, further comprising: a direct-acting guide device; 3. The direct-acting guide device according to claim 1 or 2, wherein the width of the ball guide member in the left-right direction at the outer end in the front-rear direction is not more than three times the diameter of the ball.
