ABSTRACT:
A rolling guide unit may include a cylindrical shaft with track grooves in the axial direction, a hollow outer cylinder with a hole for the shaft and track grooves facing the track grooves of the shaft, balls in the track grooves, and side plates attached to the ends of the outer cylinder with ball direction turning passageways to couple the outer cylinder track grooves and the ball return passageways. The side plates may include a thin inside plate and a thick outside plate, each of which has a cross sectional surface corresponding to a cross sectional surface of the outer cylinder. A mountain-shaped bridge portion having an arc-shaped cross sectional groove and defining an inwardly curved track is provided on the surface of the inside plate between the openings for the direction turning passageway and the return passageway. On the outside plate, a direction turning passageway U-turn portion is formed like an arc-shaped notched groove to correspond with the openings of the inside plate.
