内ユニツト。 A track rail having a track formed on both sides of the upper surface in the longitudinal direction of a long member and a slide unit having a similar track formed at a position opposite to the track are transferred between each track in three or more rows. In a linear motion rolling guide unit that provides infinite linear motion guidance via a moving body, a large number of rollers are inserted between the tracks on the top surface, and a large number of balls are inserted between the tracks on the side surface, and the arrangement of the rollers is A linear motion rolling guide unit that is of a parallel type and is characterized in that the raceway grooves that come into contact with the balls are shaped like gossock arch grooves.
