PROBLEM TO BE SOLVED: To smoothly transfer from a wheel to rolling balls so as not to generate falling of a sash pulley when the sash pulley having the wheels and the rolling balls passes through the crossing part of hanger rails. SOLUTION: This hanging device 1 is constituted of a hanger rail 2 and a sash pulley 3. Two hanger rails 2 are crossingly laid on a ceiling. The sash pulley 3 rolls wheels 5 on the side of a vehicle body 4 to run along the hanger rail 2 and hang a partition panel with a hanging bolt 6 hung from the center. The vehicle body 4 is respectively provided with wheels on the four sides squarely crossed with each other, and rolling balls 7a, 7b in front and rear of the wheel 5 on the lower face side of the vehicle body 4. The rolling ball running faces 10a, 10b are along a wheel running face 9 in the fixed range of the crossing part and positioned on the upper position therefrom, and extended to an expanding slot side. The rolling balls 7a, 7b are arranged on the lower face side of the vehicle body 4 and over the wheel 5. In the crossing part of the hanger rails 2, the rolling balls 7a, 7b smoothly run the sash pulley 3 instead of the wheel 5 positioned on the expanding slot.
