PURPOSE:To facilitate installation to a movable body and adjustment of pre-load by connecting a pair of sliding-base half bodies having many rollers to each other by means of an elastically deformable top board which connects the top surfaces of said half bodies. CONSTITUTION:Each of a pair of sliding-base half bodies 1 having nearly an L-shaped longitudinal section, has a horizontal part 1a and a vertical part 1b which extends downward from one end of the horizontal part 1a, and is connected to the other by a top board 3, which connects their top surfaces forming a downward recess part 4, while which is elastically deformable in a position between both of the sliding-base half bodies. Thereby, in order to give a defined pre-load to a bearing, one of the sliding-base half bodies 1 is pressed toward a track base 5 side with an adjusting bolt 24 which is advanced from a movable body A side, causing the top board 3 to be subjected to elastic defomation at its thin wall part 16, to adjust the pre-load. The sliding-base half bodies 1 are installed to a movable body A with bolts 19. |
