Therefore, the number of parts is increased to three, which is expensive. When the roller 5 is rotatably supported on the support part 2 by the support shaft 4, the support shaft 4 is supported from one support hole of the support part 2 to the roller 5 and the other support shaft of the support part 2 is supported. Since one end or both ends of the support shaft 4 must be deformed after being inserted into the hole, it is difficult to attach the roller 5, that is, to assemble the roller 5.

Furthermore, since the side surface of the support portion 2 is formed in a U shape, the support portion 2 is deformed when an external force F is applied to the support portion 2 by the cord C, as shown in FIG. 5 (a). Due to damage to the support shaft 4 or close contact with the support portion 2,
There is a possibility that the roller 5 may not rotate properly. Further, as shown in FIG. 6, when the string hooks 1 are attached to each other and the opposing string hooks 1 come into contact with each other, the supporting portions 2 come into contact with each other at the open end portions thereof. As a result, the rollers 5 are in contact with each other, which causes inconveniences such as damage to the rollers 5 and difficulty in rotation.

The present invention has been made in order to eliminate the above-mentioned inconvenience, and has a small number of parts, is inexpensive, is easy to assemble, and is capable of minimizing the deformation of the supporting portion even when an external force from the cord acts. Accordingly, it is possible to prevent the rotation of the rollers from being hindered, and to provide a string hanger that does not hinder the rotation of the rollers even when the string hangers come into contact with each other.

Since it can be inserted and attached from the side, it becomes easy to assemble.

Further, when the external force F by the string C acts,
Although the upper piece 12u of the support portion 12 is curved upward, the side surface shape of the support portion 12 that pivotally supports the roller body 14 is a square shape, so that the deformation of the support portion 12 is minimized, so that the roller body 1
4 is not hindered from rotating and rotates smoothly. Further, even if the string hooks 11 facing each other come into contact with each other, since the support portions 12 are formed in the square shape, the support portions 12 come into contact with each other, and the roller bodies 14 do not come into contact with each other. The roller body 14 is not damaged or becomes hard to rotate.

Since the thickness of the lower piece 12d corresponding to the roller portion 14r to which the tension of the cord C is applied is increased up to the lower end of the groove 14g, the cord C has the lower piece 12d and the roller portion 14r.
