SUMMARY OF THE INVENTION According to the present invention, a hanging object is hanged on a hanging portion that is inserted into a rail between rails having an open lower surface so that the rail can travel. In the hanging runner that can be lowered, the running portion that is locked to the rail upper surface inside the rail is horizontally rotatably connected to the upper end of the shaft portion inserted between the rails, and the hanging object is It is characterized in that it is a hanging runner in which a hanging part to be hung is connected to a lower end of a shaft part protruding below the rails so as to be horizontally rotatable.

The above-mentioned suspension runner can be formed of a synthetic resin having a low contact resistance such as a polycarbonate resin, a polyacetal resin, or a fluororesin. In addition, the traveling portion, the shaft portion, and the suspending portion may be horizontally rotatably connected by inserting the end portion of the shaft portion into the hole portion of the traveling portion and the suspending portion, or by using a pin or a screw. It is also possible to connect them horizontally such that they can be rotated horizontally with a connecting member such as.

That is, when the hanging runner is moved along the rail of the rail, the contact resistance generated at the contact portion between one rail and the running portion is large, and the contact resistance at the contact portion between the other rail and the running portion is large. When the generated contact resistance becomes smaller, the running portion horizontally rotates around the shaft portion due to the difference in the contact resistance, and the contact surface of the running portion that is in contact with the rail is rotationally displaced in the circumferential direction. The contact resistance and sliding noise generated at the contact part between the rail and the running part are reduced. Moreover, the direction of the suspending portion is displaced with respect to the moving direction of the suspending runner (approximately 36
0 degree).
