In addition, when the hinge plate 200 is moved rearward and the main body 80 is opened, the position of the first link member 300 and the second link member 400 is the first hinge point (from the front to the rear) 310, the second hinge point 320, the third hinge point 410, and the fourth hinge point 420 are arranged in this order, and the fourth hinge point 420 and the second hinge point 320 are disposed from the top to the bottom. The first link member 300 and the second link member 400 are hinged plates when the main body 80 is opened by being arranged in the order of the third hinge point 410 and the first hinge point 310. It is inclined opposite to the inclination direction of 200 to stably support the hinge plate 200, and has an effect of improving the holding force of the first link member 300 and the second link member 400.

2 and 9, the second link member 400 has both sides formed to be wide as the width of the main body 10, one end of which is mounted to the hinge base 100, and the other end of the second link member 400. Mounted on the plate 200 is disposed long in the vertical direction.

The second link member 400 blocks the rear of the main body 80 when the hinge plate 200 is moved to the rear to open the main body 80, so that the main body 80 and the movable body 90 ), The wires such as FPCB connecting to block the invisible from the rear, there is an effect that the appearance of the mobile terminal looks simple and neat.

In addition, one end of the second link member 400 is disposed behind the first end of the first link member 300, and the other end is disposed behind the other end of the first link member 300, thereby providing the first link. The member 300 and the second link member 400 support the hinge plate 200 forward and backward, respectively, to prevent the hinge plate 200 from rotating arbitrarily, and an external force applied to the hinge plate 200. By dispersing the effect of improving the holding force for supporting the hinge plate 200.
