。[Scope of Claim for Utility Model Registration] 1. Raceway grooves are formed in the longitudinal direction on a part of the side wall surface of a table or bed formed by making a thin steel plate into a U-shaped cross section, and the raceway grooves of the table and bed face each other. The lower plate attached to both longitudinal ends of the bed is formed into a trapezoidal shape, and its tapered surface is located on the ball side, and one end is connected to the ball through a ball having a retainer. It is located on the bed side from the center, and the other end is on the table side beyond the center of the ball, and the upper plate attached to both longitudinal ends of the table leaves a nearly constant gap in the shape of the inner peripheral surface. A ball bearing for linear motion made of a thin steel plate, characterized in that the ball bearing is shaped to fit the lower plate. 2. The retainer of the ball has an I-shaped cross section, and a window for retaining the ball is formed approximately in the center of the I-shape, and an intermittent annular protrusion such as a semicircle is formed at the periphery of the window. A ball bearing for linear motion made of a thin steel plate according to claim 1, characterized in that the ball bearing is made of a thin steel plate and is adapted to hold balls.
