PROBLEM TO BE SOLVED: To provide a brake device of a slide rail capable of being easily and inexpensively produced, utilizing characteristics of a basic structure of a slide rail.SOLUTION: A slide rail is made of an outer member 1, a ball retainer 2, plural balls 4, and an inner member 3. A brake projection part 5 which projects toward a substrate 21 direction of the ball retainer 2 by predetermined dimension, is formed on at least one side end part substrate of the outer member 1 and in a slide direction of the inner member 3. A synthetic resin brake push-up member 6 for applying predetermined elasticity to the ball retainer 2 is integrated on a slide side end part of the substrate 2 of the ball retainer 2. By such a structure in which, the slide side end part contacts the brake projection part 5 and pushes up the slide side end part of the ball retainer 2, the balls 4 on the slide side end part are pressed to a ball slide surface of the outer member 1.SELECTED DRAWING: Figure 3 |
