The plate spring 700 is formed in a bar shape and has an elastic portion 710 bent in the direction of the spring groove 620 of the rotate arm 600. A stop protrusion 720 is protruded at an end of the elastic portion 710.

When the rotation arm 600 rotates, the stop protrusion 720 rotates in contact with the spring groove 620 and is inserted into the stop groove 630 by an elastic restoring force when moving to the stop groove 630 to be inserted into the rotation arm. It will block the random rotation of 600.

Here, in one of the stop grooves 630, the stop protrusion 720 is inserted when the terminal is folded, and the other stop protrusion 720 is inserted when the terminal is unfolded.

On the other hand, the first magnet 810 and the second magnet 820 are formed in a plurality, respectively, and are fixed to be spaced apart from the left and right ends of the main cover 120 at regular intervals.

That is, the first magnet 810 is fixed to the main cover 120 disposed on the left side of the center cover 110, and the second magnet 820 is disposed on the right side of the center cover 110. It is fixed to the main cover 120.

Accordingly, when the terminal is folded, the first magnet 810 and the second magnet 820 are adjacent to each other, and the main cover 120 is supported so as to maintain the folded state by an attractive force action.

Here, it is preferable that the first magnet 810 has an upper end of an N pole and a lower end of an S pole, whereas the second magnet 820 has an upper end of an S pole and a lower end of an N pole.

In addition, the cover magnet 830 has a rectangular shape and consists of a plurality of pieces. That is, the cover magnets 830 are fixedly mounted by being disposed in each of the two main covers 120 by four,

The wing magnets 840 have the same square shape as the cover magnets 830, and are fixedly mounted to each of the two wing plates 130 by four.

The cover magnet 830 and the wing magnet 840 support the wing plate 130 to be in close contact with the main cover 120 by an attractive force action.

Meanwhile, the front plate 900 is disposed above the flexible display 140, is formed in a frame shape covering an edge of the flexible display 140, and is coupled to the main cover 120.

The front plate 900 has a function of improving durability and preventing damage by bringing the edge of the flexible display 140 into close contact with the main cover 120.

In the foldable portable terminal according to the first embodiment of the present invention having the above configuration, when the flexible display 140 is folded, the guide member 400 and the rotating member 300 rotate together and slide, so that the By compensating for a change in the gap according to the folding of the flexible display, the flexible display can be stably folded in a streamlined shape, and an effect of improving durability is provided.

The rotate arm 600 has one end fixedly mounted to the wing plate 130, and the other end rotatably mounted along the first swing groove 510, so that the rotation angle and direction of the wing plate 130 Guide to ensure stable operation.

By providing the plate spring 700 in which the elastic part 710 protrudes in the direction of the other end of the rotating arm 600, the volume is reduced compared to the coil spring used to prevent arbitrary rotation of the terminal. Provides the effect of being compact and lightweight
