The cable 26 is configured by, for example, FPC. Accordingly, since the cable 26 has a certain degree of flexibility, it can be easily looped around the shaft portion 32.

  Here, the cable 26 is arranged so that the distance from the shaft portion 32 to the cable 26 (distance r shown in FIG. 6) is substantially constant in the looped part (part A shown in FIG. 6). The Here, the distance r is a distance shorter than the distance from the shaft portion 32 to the inner surface of the substantially cylindrical portion of the hinge cover 31 (distance R shown in FIG. 6).

As shown in FIG. 6, the distance R from the shaft portion 32 to the substantially cylindrical portion of the hinge cover 31 is configured to be substantially constant. That is, since the hinge cover 31 is formed in a substantially cylindrical shape, the distance from the shaft portion 32 is maintained at a substantially constant distance R in portions other than the protruding portions 311 and 312 of the hinge cover 31. In the protruding portion 312 fitted to the rear case 25, as shown in FIG. 6, the distance from the shaft portion 32 to the protruding portion 312 (R + α shown in FIG. 6) is substantially cylindrical of the hinge cover 31 from the shaft portion 32. It is comprised so that it may become larger than the distance R to the inner wall of a part.
The distance from the shaft portion 32 to the protruding portion 312 is substantially the same as the distance R from the shaft portion 32 to the inner wall of the substantially cylindrical portion of the hinge cover 31.

With such a configuration, the hinge cover 31 (particularly the protruding portion 311 and the protruding portion 312) does not interfere with the loop of the cable 26.
The projecting portion 311 and the projecting portion 312 are configured to project outward and have a distance from the shaft portion 32 that is greater than the distance from the shaft portion 32 to the inner wall of the cylindrical portion of the hinge cover 31.
For this reason, it is suppressed that the protrusion part 311 and the protrusion part 312 interfere with the loop of the cable 26. FIG. Thereby, when the protrusion part 311 and the protrusion part 312 protrude inward (inner space side of the hinge cover 31), or the distance from the shaft part 32 to the protrusion part 312 is a cylinder of the hinge cover 31. The loop diameter of the cable 26 can be increased compared to the case where the distance is smaller than the distance to the inner wall of the portion.
Accordingly, the degree of freedom of the cable 26 can be improved in the hinge portion 3.

Incidentally, as described above, the upper housing 1 and the lower housing 2 are configured to be rotatable with respect to each other about the shaft portion 32 as a central axis. FIG. 6 shows a case where the upper housing 1 and the lower housing 2 are in the open state.

Thereby, compared with the case where the hinge part is covered with a plurality of external members, the hinge part 3 can be shown in a simple structure, and by extension, the upper housing 1 and the lower housing 2 can also be shown in a simple structure. It becomes.
Moreover, since the protrusion part 311 and the protrusion part 312 protrude outward, the space in the hinge part 3 can be ensured and interference with the cable 26 in the hinge part 3 can be suppressed.

  Further, the mobile terminal 100 of the present embodiment is configured such that the cable 26 loops (winds) around the shaft portion 32 once in the hinge portion 3. For this reason, the cable 26 can be easily routed in the hinge part 3, and the degree of freedom in designing the hinge part 3 can be improved.

Further, in the portable terminal 100 of the present embodiment, in the hinge portion 3, the distance r from the shaft portion 32 to the loop portion of the cable 26 is the distance R from the shaft portion 32 to the inner wall portion of the substantially cylindrical portion of the hinge cover 31. It is configured to be always smaller than.
On the other hand, the distance R + α from the shaft portion 32 to the inner wall of the protruding portion 312 portion of the hinge cover 31 is configured to be larger than the distance R from the shaft portion 32 to the inner wall portion of the substantially cylindrical portion of the hinge cover 31. For this reason, when the protrusion 312 is fitted to the lower housing 2, the space inside the hinge 3 is not compressed, and the degree of freedom of behavior of the cable 26 in the hinge 3 is improved.

Further, in the portable terminal 100 of the present embodiment, the lower casing 2 has the front case 21 (second case member of the present invention) and the rear case 25 (third case member of the present invention) as the inner case 24 (the present invention). (Internal mounting member). The protrusion 311 of the hinge cover 31 is fitted to the front case 21 and the protrusion 312 is fitted to the rear case 25.
