Abstract

Provided is a rolling guide device which can be produced easily and inexpensively by achieving a reduction in the number of parts constituting a slide member () and a reduction in machining worker-hours therefor. The rolling guide device includes: a raceway rail (); and the slide member () assembled to the raceway rail () through an intermediation of the large number of balls (), in which the slide member () is formed by bending a metal plate member () and has a lateral web () and a pair of flange parts () to be formed in a channel-like configuration, and in which each of the flange parts () has a track groove () in which the balls () circulate, the track groove () including a load straight-line groove () allowing the balls () to roll while bearing a load, a pair of ball deflection grooves () and releasing the balls () having rolled through the load straight-line groove () from the load while changing their direction, and a non-load straight-line groove () transferring the balls () from one ball deflection groove () to the other ball deflection groove ().
