いることを特徴とするリニアガイド装置。[Scope of Claim for Utility Model Registration] A guide rail with ball rolling grooves extending in the axial direction on each side of the left and right sides, and balls having a saddle shape to be placed over the guide rail and facing the ball rolling grooves, respectively. A rolling groove is provided on the inner surface of each sleeve portion, and the ball can be moved along the guide rail by rolling of a large number of balls interposed between the ball rolling groove and the ball rolling groove of the guide rail. a pair of saddle-shaped end caps that are attached to each end face of the bearing body and have a semicircular groove space forming a circulation path for the balls; In the linear guide device having a cylindrical return guide, each sleeve portion of the end cap is formed with a return guide insertion groove that penetrates the recessed groove space, and the return guide insertion groove is configured such that the end cap is inserted into the bearing. The return guide has a lower end opening that allows the return guide to be inserted from below when attached to the main body, and the return guide has a lubricating oil groove with one end closed, and the return guide is connected to the return guide. A linear guide device characterized in that a minute convex portion is formed so that the minute concavo-convex portion bites into and fits into the return guide insertion groove when the linear guide device is inserted into the return guide insertion groove.
