The rotation module 150 is configured to relatively rotate the first and second bodies 110 and 120 between the closed state and the open state. That is, the rotation module 150 is connected to the first and second bodies 110 and 120 so that the first and second bodies 110 and 120 are exposed so that the first and second surfaces are exposed, . Referring to these drawings, the rotation module 150 can be disposed on the side surfaces of the first and second bodies 110 and 120, specifically, the side surfaces facing each other in the open state.

Referring to these drawings, the rotation module 150 is formed to relatively rotate the first and second bodies 110 and 120 about the rotation axis 152. [ The first and second bodies 110 and 120 are relatively rotated between the closed state (see FIG. 1) and the open state (see FIG. 2).

The rotation module 150 includes a bracket 151, the rotation shaft 152, and protrusions 153a and 153b.

The bracket 151 is connected to the first body 110 and the rotation axis 152 protrudes from the bracket 151 and rotates together with the first body 110. The second body 120 is rotatably connected to the rotating shaft 152. The second body 120 may be provided with a frame so that the rotation shaft 152 is inserted and rotated.

Referring to these drawings, a pressing unit 160 is mounted on the second body 120.

[ . Although the flexible display 141 is elastically deformed and restored in the present embodiment, the same mechanism can be applied to the keypad 142 as well.

The pressing unit 160 includes a supporting member 161 and a torque transmitting portion 162.

The support member 161 is formed to support one side of the flexible display 141 and is disposed at a position where at least a portion of the support member 161 is pressed by the rotation of the rotation module 150.

The protrusions 153a and 153b of the rotation module 150 are formed to protrude from the outer periphery of the rotation shaft 152 and press at least a part of the support member 161 by the rotation of the rotation shaft 152. The rotation force transmitting portion 162 is configured to rotate the portion supporting the one surface of the flexible display 141 in a direction to press the flexible display 141 when at least a part of the support member 161 is pressed.

The support member 161 includes a support portion 161a, a guide portion 161b, and an extension portion 161c. The supporting member 161 is formed of a metal such as stainless steel and the supporting portion 161a, the guide portion 161b and the extending portion 161c may be integrally formed by pressing one metal plate.

The supporting portion 161a is formed to support one surface of the flexible display 141. [ Specifically, for example, a flexible circuit board (not shown) for driving the flexible display 141 is mounted on the back surface of the flexible display 141, and the support portion 161a supports the back surface of the flexible circuit board along one direction And a plate member having both ends thereof formed in one direction.

The guide portion 161b may be formed on at least one of both ends of the support portion 161a and at least a part of the rotation force transmitting portion 162 is connected to the guide portion 161b to guide the rotation of the support portion 161a . The guide portion 161 includes a body connected to the support portion 161a and a through hole formed to be long in one direction in the body.

The extension portion 161c extends from the support portion 161a or the guide portion 161. [ Referring to these drawings, the extension portion 161c extends in the direction intersecting the extension portion 161c of the guide portion 161, and by the relative rotation of the first and second bodies 110 and 120, So that at least a portion thereof is disposed within a range in which the rotation axis 152 of the rotation module 150 rotates. More specifically, the extended portion 161c is disposed within a range in which the projections 153a and 153b of the rotating shaft 152 rotate, and the protrusions 153a and 153b are rotated in the relative rotation of the first and second bodies 110 and 120, 153b.

The rotation force transmitting portion 162 includes a rotation bar 162a.

One end of the rotation bar 162a is rotatably connected to the second body 120 and the other end is connected to the guide part 161b. The rotation bar 162a is at least partially bent between both ends and one end of the rotation bar 162a is positioned at a position away from the support portion 161a in the direction from the extension portion 161c toward the support portion 161a, 2 body (120). The second body 120 is formed with a fastening portion to which the outer periphery of the rotary bar 162a is rotatably inserted. The support portion 161a is formed so that the rotation center of the support portion 161a is separated from the support portion 161a and the extension portion 161c. When the extension portion 161c is pressed, the support portion 161a and the extension portion 161c are moved in the same direction .

The guide portion 161b is elongated in one direction so as to guide sliding of the other end of the rotation bar 162a and a lubricating member 163 is attached to the guide portion 161b. The lubrication member 163 is provided with a guide hole 163a which slides while the other end of the rotation bar 162a contacts with the lubrication member 163. The lubrication member 163 is formed of a material having a lower friction coefficient than the support member 161. [

The lubrication member 163 is made of, for example, polyoxymethylene (POM), and the rotation bar 162a causes a lubrication friction with the lubrication member 163 during sliding. Here, the lubrication friction means the friction by the lubrication member.

Hereinafter, the variable mechanism of the input / output unit will be described with reference to Figs. 6A and 6B. 6A and 6B are cross-sectional views taken along lines VIa-VIa and VIb-VIb of FIGS. 1 and 2, respectively.

Referring to these drawings, a plurality of protrusions 153a and 153b protruding from the outer circumference of the rotary shaft 152 are provided. The plurality of protrusions 153a and 153b are spaced apart from each other at the rotary shaft 152, The extension portion 161c is disposed between the plurality of projections 153a and 153b so as to be pressed against the rotation of the rotation shaft 152 in opposite directions opposite to each other.

6A, in the closed state, the rotation bar 162a is disposed adjacent to one end of the guide hole 163a, and the flexible display 141 is supported by the support portion 161a in a bent state toward the inside of the second body 120 The back surface is supported.

6B, when the first and second bodies 110 and 120 rotate relative to each other in the closed state, the extension portion 161c, which rotates together with the second body 120, And the support portion 161a moves together with the extension portion 161c by the pressing so as to push the flexible display 141. [ The flexible display 141 is resiliently restored by pressing the support portion 161a to be flat.

One end of the flexible display 141 is fixed to the second body 120 and the other end of the flexible display 141 is formed to be movable along at least a part of the second body 120.

Specifically, a guide groove 143 is formed on a surface defining the display hole 141a, and the other end of the flexible display 141 is inserted into the guide groove 143. [ The guide groove 143 is formed to be recessed in the moving direction of the flexible display 141 to guide the other end of the flexible display 141 to move.

When the flexible display 141 changes from a curved surface to a flat surface, the distance between the opposite ends of the flexible display 141 is distant. Therefore, the sliding of the other end of the flexible display 141 helps the flexible display 141 to easily change from a curved surface to a flat surface.

Referring again to FIG. 6A, when the first and second bodies 110 and 120 rotate relative to each other in the open state to the closed state, the extension portion 161c rotating together with the second body 120 is rotated by the second projection 153b And the support portion 161a moves together with the extension portion 161c by the pressing so as to press the flexible display 141. [ The flexible display 141 is elastically deformed by pressing the support portion 161a toward the inside of the second body 120 to form a curved surface. Accordingly, in the closed state, the flexible display 141 has a shape corresponding to the curved surface of the keypad 142 or the first front surface.

7A and 7B are cross-sectional views illustrating another embodiment of a mobile terminal according to the present invention.

Referring to these drawings, the pressing unit 260 is connected to the other end of the flexible display 241, and is configured to pull the other end of the flexible display 241.
