A part of the groove line 20 includes a guide portion 21 that protrudes in the rotation direction of the hinge cap 5, and a large insertion port is formed between the groove line 20 and the guide portion 21, and the circumferential direction from above. A guide groove 22 having a smooth slanted shape from the side surface to the bottom surface of the groove line 20 is provided.

  On the other hand, the drop-off prevention protrusion 19 located at the lower end of the hinge cap 5 is provided in the circumferential direction so as to have a bending portion 23 of stopper means protruding toward the rotation direction of the hinge cap 5 as shown in FIGS. An extending notch 24 is provided.

  The operation of an example of the embodiment of the present invention will be described below.

  When attaching the strap string S to the foldable mobile phone, the cover portion 17 of the hinge cap 5 is inserted into the rotation groove 8 and the guide portion 21 is disposed below the first opening 11 in advance. The distal end annular portion Sa of the strap string S is inserted into the guide groove 22 through the first opening 11 as shown in FIG. Next, the guide portion 21 is arranged below the second opening 12 by rotating the hinge cap 5, and the tip annular portion Sa of the strap string S is guided to the second opening 12 as shown in FIG. It pushes out from the groove 22 to the outside of the key-side casing 2 through the second opening 12. Subsequently, in a state where the strap string S is passed through the first opening 11 and the second opening 12, the strap string S is passed by passing the band portion Sb of the strap string S on the opposite side through the tip annular portion Sa of the strap string S. Is hooked on the strap hooking portion 10 and attached to the foldable mobile phone. Here, when the strap string S is attached to the shoulder portion of the key-side casing 2 in the foldable mobile phone, the key-side casing 2 does not interfere with the display-side casing 3. When the display-side casing 3 is opened, as shown in FIGS. 23 and 24, the strap strap S attachment portion is positioned in the gap L, and the key-side casing 2 and the display-side casing 3 are located. When is closed, as shown in FIG. 25, the strap strap S attachment portion is located outside. Further, when the distal end annular portion Sa of the strap string S is taken out from the second opening 12, the second opening 12 depends on the shape of the second opening 12 or the like and the material of the distal end annular portion Sa of the strap string S. You may make it easy to pull out from the lower part.

  At the same time, when the hinge cap 5 is rotated, as shown in FIGS. 19 to 22, the drop-out prevention protrusion 18 of the hinge cap 5 slides in the drop-off prevention groove 9 of the casing 2 on the key side, and the hinge cap 5 The drop-off prevention protrusion 19 positioned at the lower end of the first member passes over the first stopper portion 13 and the second stopper portion 14 while the bending portion 23 is bent toward the notch 24. Here, as shown in FIGS. 19 and 21, when the drop-out prevention projection 19 at the lower end contacts the first stopper portion 13, the guide portion 21 of the hinge cap 5 is positioned below the first opening 11. The hinge cap 5 is made rotatable when the first stopper portion 13 is overcome. Further, as shown in FIGS. 21 and 22, when the drop-off preventing projection 19 at the lower end gets over the second stopper portion 14, the guide portion 21 of the hinge cap 5 is positioned below the second opening 12. Furthermore, when the lower-end drop-off preventing projection 19 gets over the first stopper portion 13 or the second stopper portion 14, it prevents the lower-end drop-off preventing projection 19 from jumping in the opposite direction depending on the direction of the notch 24 of the lower-end drop preventing projection 19. The rotation of the hinge cap 5 is restricted to one side.

  Thus, according to an example of the embodiment of the present invention, the strap string S is attached to the shoulder portion of the key-side casing 2 by the strap string S attachment structure. It is possible to make the housing 1 simple by eliminating the need to provide a projecting portion, to prevent rattling, and to improve the design so as to be compatible with various housing designs. Moreover, since the housing 1 of the terminal device can be made into a simple shape, even when the strap device S is pulled out from the state in which the terminal device is stored in the pocket or the like, it can be smoothly taken out from the pocket or the like. Furthermore, since the strap string S can be passed through the key-side casing 2 by the rotation of the hinge cap 5 (rotating body), the attachment of the strap string S is not affected by the attachment location and can be easily attached. . Moreover, since the guide groove 22 of the guide part 21 has a smooth diagonal shape from the side surface to the bottom surface of the groove line 20 so as to form a large insertion port and go from the upper side to the circumferential direction, the annular end portion of the strap string S Sa can be easily inserted and locked.

  The strap string S mounting structure includes the first stopper portion 13 and the second stopper portion 14 that restrict the rotation of the hinge cap 5 to one side, so that the hinge cap 5 can be positioned and the guide portion 21 is provided with the first stopper portion 21. The opening 11 and the second opening 12 can be suitably moved.

  The attachment structure of the strap string S includes the hinge unit 4 in the hinge housing portion 6 of the housing 1 so that the housing 1 can be folded, and the hinge housing portion 6 has two openings 11 and 12. S can be attached to the hinge housing portion 6 which is the shoulder portion of the casing 2 on the key side, and the design can be further improved. In addition, since the left and right hinge storage portions 6 are provided on both shoulders of the key-side casing 2, the strap string S can be freely attached to the left and right. Furthermore, since the strap string S can be attached to the strap hooking portion 10 of the hinge storage portion 6 and disposed without interfering with the display-side casing 3, the strap string S can be stably suspended.

  In the attachment structure of the strap string S, the hinge cap 5 that guides the strap string S can hide the hinge unit 4, so that the design can be further improved. Further, even when an antenna that can be pulled out is built in the terminal device, it is possible to easily prevent rattling.
