Abstract:
1. A rolling guide device, comprising: a raceway rail having a longitudinally extending rolling groove for a large number of balls; and a slide member assembled to the raceway rail through an intermediation of the large number of balls, wherein the slide member is formed by bending a metal plate member and has a lateral web and a pair of flange parts provided upright on the lateral web to be formed in a channel-like configuration, wherein each of the flange parts includes wherein the ball deflection grooves and the non-load straight-line groove of the track groove are opposed to the raceway rail so that the balls are retained in the ball deflection grooves and the non-load straight-line groove, and wherein the ball deflection grooves are formed so as to be shallowest at the positions where the ball deflection grooves are connected to the load straight-line grooves and deepest at the positions where the ball deflection grooves are connected to the non-load straight-line grooves.
