PURPOSE:To reduce the number of roll faces and save the labour of assembly work by placing rollers in two load grooves which are formed on a friction base at the end of the horizontal part and at the lower end of the vertical part thereof and also placing rollers between the upper part of a track and roll face at the side thereof. CONSTITUTION:Friction bases 1 run at the side of the lower face of the tip end of the horizontal part 2a and the side of the internal face of the lower end of a vertical part 2b along the related axial direction and constitute load ranges of a roller endless track. The friction bases have a load groove 9 having a travelling flat face. A grooved loadless part 10 which is formed together with the load groove 9 along the axial direction and constitutes a loadless range of a roller endless rail is formed on both the upper face of the tip end part of the horizontal part 2a and the external face of the lower end part of the vertical part 2b. After a fitting bolt 7 is tightened loosely, an adjusting bolt 26 which is thrusted from the side of a movable body 20 is pressed toward the horizontal part 20 from a fitting part 2c with respect to the upper part of the slide rail. Preadjustment can be thus performed. |
