PURPOSE:To permit even large-size partition wall to be easily moved by a method in which pairs of main wheels pivotally attached to the side frame of a runner frame are combined with rails, and racks set on the running rails are engaged with a pinion. CONSTITUTION:Pairs of main wheels 14 are pivotally attached to the inside of the side frame parts 12 of a runner frame 10, and a running rail R is combined with the wheels 14 in a form of passing the rail R between the side frame parts 12. Racks 21 are set on the rail R, and a pinion 22 pivotally attached to the lower frame part 11 of the frame 10 is engaged with the racks 21. The pinion 22 is rotationally operated by a motor M1 built in the partition wall W, and the frame 10 is allowed to run and move through the racks 21. |
