PROBLEM TO BE SOLVED: To provide a suspended roller which can reduce manufacturing costs by making a manufacturing time shorter than ever before and simplifying assembling operations. SOLUTION: This suspended roller comprises: base part 1 which is formed in an approximately square shape in a plan view, and which holds an upper end of a connecting rod 2 for suspending a movable wall; an upper plate 9 which is mounted on the top-surface side of the base part 1, and in which a hole part 8 is provided in a position near the outside of the corner part of the base part 1; a plurality of directional wheels 3 which are arranged on the top-surface side of the top plate 9, and which can be freely rotated around a vertical shaft center; and four ball holding column parts 12 which are arranged on the undersurface side of the top plate 9 in such a manner as to correspond to the hole part 8. In the base part 1, a horizontal pivot 7, on which a wheel 6 is pivotally supported, is inserted and fixed into the hole part 5 of each of four side surfaces 1a. A rolling ball 11 is held on the undersurface side of the column part 12; a screw hole part 10 is provided on the top-surface side of the column part 12; and the column part 12 is fixed in such a manner that a bolt member 4 inserted through the hole part 8 from above the top plate 9 is screwed into the screw hole 10. Additionally, the directional wheel 3 is pivotally attached to the upper end of each bolt member 4. COPYRIGHT: (C)2007,JPO&INPIT
