Claims

[Claims for Utility Model Registration] 1. A roller bearing unit for linear motion in which a casing straddled by a straight rod-shaped traffic rail can perform infinite linear motion via a large number of infinitely circulating rollers, the diameter and length of which are different. An endless circulation path is provided in which a large number of substantially equal cylindrical front rollers are alternately arranged adjacent to each other with their rotation axes differing by 90 degrees, and circulate endlessly. A direction changing path having a substantially square cross section for changing the direction of the rolling rollers is formed by connecting both ends of the track and the return path, and is attached separately to both front and rear ends of the casing. The side plate includes a side plate main body in which a switching cavity is recessed, the outer edge of which is a semicircular right-angled V-shaped groove forming two outer peripheral side surfaces of the direction switching path having a substantially square cross section; A semicircular right-angled V-groove forming two inner circumferential sides of the channel is recessed on the outer edge, and has a divided structure consisting of two members, including a side plate spacer fitted into the conversion cavity. Split side plates for linear motion roller bearing units. 2. The divided side plate of a linear motion roller bearing unit according to claim 1, which is a side plate spacer in which the vicinity of the outer edge of a semicircular right-angled V-shaped groove is cut out.
