<P>PROBLEM TO BE SOLVED: To provide a slide rail device having a lower rail having a uniform cross section, an upper rail having a uniform cross section and slidably fitted to the lower rail, and balls inserted between the lower rail and the upper rail, the slide rail device having favorable balance in an adhesion preventing property against the indentation of the ball and a rolling property of the ball. <P>SOLUTION: A lower-rail lower ball contact R part and a lower-rail upper ball contact R part in contact with a lower ball and an upper ball, respectively, are formed in a lower rail. When the lower ball diameter is defined as r1, the upper ball diameter is defined as r2, the diameter of the lower-rail lower ball contact R part is defined as R1, and the diameter of the lower-rail upper ball contact R part is defined as R2, R1≥1.1r1 and R2≥1.1r2 are satisfied. <P>COPYRIGHT: (C)2012,JPO&INPIT |
