Claims

[Scope of Claim for Utility Model Registration] (1) An extended guide rail having axial ball rolling grooves on both sides, and a guide rail that is loosely fitted into the guide rail so as to be movable in the axial direction, and A slider having a ball circulation unit including a ball rolling groove facing the ball rolling groove and a ball return passage parallel to the ball rolling groove, and a large number of balls rotatably inserted into the ball circulation path of the ball circulation unit. In the assembly type linear guide device, the slider has a ball circulation unit that is engaged and fixed to a top plate portion with bolts, wherein the top plate portion is formed into a planar shape, and the top plate portion and the ball circulation unit are connected to each other. 1. An assembly type linear guide device characterized in that the assembly type linear guide device is configured to be positioned through a positioning pin and engaged and fixed with a bolt. (2) The assembly type linear guide device according to claim (1), wherein the slider is loosely fitted into the guide rail so as to straddle the guide rail. (3) The assembly type linear guide device according to claim (1), wherein the guide rail has a substantially U-shaped cross section, and the guide rail is loosely fitted into a recess of the guide rail.
