ABSTRACT:
A linear rolling motion guide apparatus comprises a track member as a guide rail formed with a track extending in a longitudinal direction thereof, a movable member as a movable block formed with a rolling member circulation passage including a loaded rolling member rolling track corresponding, in position, to the track of the track member, a number of rolling members such as balls rolling in the rolling member circulation passage, the movable member being arranged to be movable relatively to the track member by a rolling motion of the rolling member and a rolling member connection assembly, as a retainer, mounted to the movable member, the rolling member connection assembly having a flexible belt-shaped member supporting the rolling members in series to be rotatable. The movable member is formed with a single material and the movable member is integrally formed with guide portions, for guiding the flexible belt-shaped member, to both sides of the loaded rolling member rolling track with the same material as that of the movable member through the same manufacturing process therefor.
