１項記載の薄肉形直線運動用転がり軸受。[Claims for Utility Model Registration] (1) A pair of raceways in which raceway grooves are formed in the longitudinal direction of the side surfaces of a prismatic member are arranged with the raceway grooves facing each other, and a large number of flat plates with rolling elements are provided between the raceway grooves. In a rolling bearing for finite linear motion in which a retainer of the shape of a shape is inserted to move a way in a straight line, a concave notch is formed on the end face along the raceway groove of the side surface where the raceway groove is formed in the way. A rolling bearing for finite linear motion, characterized in that a spring portion is formed in the retainer at a position corresponding to the concave notch so as to protrude so as to come into contact with the concave notch. (2) The thin-walled utility model according to claim 1, wherein the recessed portion of the wayway is a substantially U-shaped recess formed over almost the entire length of the wayway in the longitudinal direction. Rolling bearing for linear motion.
