Claims (6)

A guide rail having a rolling element guide surface, and a loaded rolling element guide that is disposed so as to be relatively movable with respect to the guide rail and that forms a rolling element track along with the rolling element guide surface. A slider having a surface, and a plurality of rolling elements that roll on the rolling element raceway, the slider having a rolling element return passage in which the rolling elements roll in an unloaded state, A pair of end caps that are attached to both ends of the slider body in the moving direction and that form direction change paths that are respectively connected to both ends of the rolling element raceway and the rolling element return path. An endless circulation path is configured by the moving body track path, the pair of direction change paths, and the rolling element return path, and the endless circulation path includes a plurality of rolling element accommodation portions that individually accommodate the rolling elements. Before A rolling element was housed linear guide apparatus rolling elements accommodation belt which is formed into a closed end shape to align the rolling element row in the arrangement direction of the endless circulation passage is incorporated,
The rolling elements accommodation belt is disposed one by one for one endless circulation path, the developed length of that is the center distance between the rolling elements between the rolling element accommodating portions located at both ends thereof, said slider A linear guide device characterized by being shorter than the remaining path length of the infinite circulation path when one end cap is removed from.   Both ends of the rolling element accommodation belt are opposed to each other in the endless circulation path in a non-contact state, and one or more rolling elements not accommodated in the rolling element accommodation section are disposed between the opposed both ends. The linear motion guide device according to claim 1, wherein a moving body is incorporated.   The rolling element housing belt has an abutting surface that abuts against a rolling element that is not accommodated in the rolling element accommodating portion, and the abutting surface moves the abutting rolling element in the outer circumferential direction of the infinite circulation path. The linear motion guide device according to claim 2, wherein the linear motion guide device has an allowable shape. A guide rail having a rolling element guide surface, and a loaded rolling element guide that is disposed so as to be relatively movable with respect to the guide rail and that forms a rolling element track along with the rolling element guide surface. A slider having a surface, and a plurality of rolling elements that roll on the rolling element raceway, the slider having a rolling element return passage in which the rolling elements roll in an unloaded state, A pair of end caps that are attached to both ends of the slider body in the moving direction and that form direction change paths that are respectively connected to both ends of the rolling element raceway and the rolling element return path. A plurality of infinite circulation paths are configured from the moving body track path, the pair of direction change paths, and the rolling element return path, and each of the infinite circulation paths has a plurality of rolling element accommodating portions that individually accommodate the rolling elements. Moving body A method of manufacturing a linear guide apparatus rolling elements accommodation belt which is formed into a closed end shape aligning the separate component to accommodate the rolling elements as rolling element row in the arrangement direction of the endless circulation passage is incorporated,
The unfolded length of the rolling element housing belt is such that the center-to-center distance between the rolling elements of the rolling element housing portions located at both ends thereof is the remaining of the endless circulation path when one end cap is removed from the slider. Use one shorter than the path length for each infinite circuit ,
A rolling element row insertion step for inserting a rolling element in a state where the rolling element is accommodated in the rolling element accommodation belt from a portion where one of the pair of lid members is removed in each endless track of the slider, and the rolling element row insertion step And a step of attaching an end cap to the slider body, and a method of manufacturing the linear motion guide device. Furthermore, when the both ends of the rolling element accommodation belt face each other in a non-contact state in the endless circulation path, the rolling element accommodation belt is not accommodated in the rolling element accommodation portion between the opposing both ends. Or use what can incorporate two or more rolling elements,
Further, after the lid member mounting step, the positions of the end portions of the rolling element housing belts in the plurality of rows of infinite circulation paths are moved in the arrangement direction so as to face the rolling element guide surface inside the slider. And a non-accommodating rolling element assembling step of incorporating one or more rolling elements that are not accommodated in the rolling element accommodating part from the opening window part that is opened to the gap between the opposing opposite ends. The manufacturing method of the linear guide apparatus of Claim 4.   The rolling element housing belt has an abutting surface that abuts against a rolling element that is not accommodated in the rolling element accommodating portion, and the abutting surface moves the abutting rolling element in the outer circumferential direction of the infinite circulation path. 6. The method of manufacturing a linear motion guide device according to claim 5, wherein a surface having a shape that allows the movement is used.
