ABSTRACT:
A rolling guide unit comprises a movable member provided with a pair of support portions extending from lateral end portions of a main body portion so as to provide a recessed portion between the main body portion and both the support portions, a guide rail disposed in the recessed portion of the movable member so that side surfaces of the guide rail face the inner surfaces of the support portions, respectively, and a number of rolling members disposed to be rollable between corresponding rolling member rolling grooves formed to the guide rail and the support portions of the movable member so that each of the rolling members contact the rolling member rolling grooves at two contact points and the the rolling members apply load to the rolling member rolling grooves, the movable member and the guide rail being relatively movable through the rolling of the rolling members. Each of the rolling member rolling grooves has an arcuate shape in section having radius of curvature larger than that of the rolling member and the contact points are displaceable along the arcuate shape of the rolling member rolling groove.
