A lower ridge 16 protruding from the inner wall of the running rail 17, which is rotatably fitted near the center of the cylindrical body and has a slit 13 in the longitudinal direction at the bottom of the cylindrical body, is used to prevent the lower roller 9 from moving. The lower spherical surface of the upper rolling wheel 8 which is closer to the horizontal axis R is supported by the upper ridge 18 protruding from the inner wall of the traveling rail 17 at a diagonally upper position substantially opposite to the lower ridge 16. A hanging door car supported by
