Therefore, the support shaft 40 has a simple shape and can be formed by a single press working.
Further, the support shaft 40 is attached to the cutout portion 21d of the guide member 20 via the collar 50. Therefore, compared with the conventional support shaft, the number of parts is increased, but the support shaft 40 itself can be processed by one press work, and the collar 50 can be formed by resin molding. The manufacturing cost of the shaft 40 and the collar 50 can be reduced as compared with the case of manufacturing a supporting shaft by processing a complicated shape from a conventional metal circular rod.
Further, since the support shaft 40 is attached to the guide member 20 via the collar 50, the support shaft 40 is rotatable with respect to the guide member 20 around its central axis. As a result, even when the hanging door is not a sliding door but a folding door, the runner structure 10 of the main hanging door can be applied.

Since the convex portion 21c is formed on the main body 21 of the guide member 20, when the guide member 20 moves along the guide rail 12, or when the guide member 20 is stationary on the guide rail 12, When the guide member 20 tries to float up from the guide rail 12 for some reason, the convex portion 21c comes into contact with the upper surface on the inner side of the guide rail 12, so that the guide member 20 is prevented from rising upward from the guide rail 12. .. Therefore, the guide member 20 does not come off from the guide rail 12.
