Abstract
The present invention provides a finite linear motion rolling guide unit comprising: a track member; and a link mechanism for holding ball rolling members which is arranged between vertically depending track portions of a sliding member which rides over the track member through the ball rolling members so as to be finitely linearly slidable. The link mechanism is simply constructed by two or more link arm members. In the relative reciprocating motion at any speed of the track member and the sliding member, a deviation movement thereof from the normal position of the ball linear moving members is prevented and, at the same time, the smooth and stable linear motion rolling guiding operation of the balls is assured.
