[0048] The inner arm 51 can extend long. The length direction of the inner arm 51 can be parallel to the length direction of the support arm 50. The inner arm 51 may include a first inner rod 511, a second inner rod 512, and an inner bridging portion 513. The first inner rod 511 and the second inner rod 512 can extend along the length direction of the inner arm 51 and can be opposite to each other. The inner bridging portion 513 can connect the upper edge of the first inner rod 511 and the upper edge of the second inner rod 512. The inner arm 51 may be made of metal. The inner arm 51 may be referred to as the first arm 51, or the lower arm 51, or the inner bracket 51.

[0049] The outer arm 52 can extend long. The outer arm 52 can be adjacent to the inner arm 51. The length direction of the outer arm 52 can be parallel to the length direction of the inner arm 51. The outer arm 52 may include a first outer rod 521, a second outer rod 522, and an outer bridging portion 523. The first outer rod 521 and the second outer rod 522 can extend along the length direction of the outer arm 52 and face each other (opposite). The outer bridging portion 523 can connect the upper edge of the first outer rod 521 and the upper edge of the second outer rod 522. The outer arm 52 may be made of metal. The outer arm 52 may be referred to as the second arm 52, the upper arm, or the outer bracket 52.

[0050] Furthermore, the outer arm 52 may surround a portion of the inner arm 51. The first inner rod 511 and the second inner rod 512 of the inner arm 51 may be located between the first outer rod 521 and the second outer rod 522 of the outer arm 52. The inner bridging portion 513 of the inner arm 51 may be located below the outer bridging portion 523 of the outer arm 52.

[0051] The support member 53 may include a rod portion 531, a stop portion 532, a cylinder portion 533, and an elastic member 534. The support member 53 may be referred to as a spring module 53.

[0052] The rod portion 531 may be located between the first inner rod 511 and the second inner rod 512 of the inner arm 51, and extend elongated along the inner arm 51. The rod portion 531 may pass through the inner rib 514 of the inner arm 51. The inner rib 514 may bend from the inner bridging portion 513 toward the first inner rod 511 and the second inner rod 512. The rod portion 531 may be divided into a first part 531a and a second part 531b based on the inner rib 514. The first part 531a may extend from the inner rib 514 in a first direction, and the second part 531b may extend from the inner rib 514 in a second direction opposite to the first direction.

[0053] The stop 532 can be coupled to the first portion 531a of the rod 531 to be movable along the length of the rod 531. The stop 532 can be located between the inner rib 514 and the outer rib 524. The rod 531 can rotate about its length axis. For example, an external thread can be formed on the outer peripheral surface of the first portion 531a, and an internal thread that engages with the external thread can be formed on the inner peripheral surface of the stop 532. In this case, if the rod 531 rotates in a first rotation direction R1, the stop 532 can move away from the inner rib 514; if the rod 531 rotates in a second rotation direction R2 opposite to the first rotation direction R1, the stop 532 can move closer to the inner rib 514. A flange 532F can be formed at the end of the stop 532 facing the inner rib 514 and located at or separated from the inner rib 514.

[0054] The cylindrical portion 533 can be coupled to the first portion 531a of the rod portion 531 to be movable along the length direction of the rod portion 531 and opposite to the stop 532. The cylindrical portion 533 can extend along the length direction of the rod portion 531, and the end of the first portion 531a of the rod portion 531 can be inserted into the cylindrical portion 533. The cylindrical portion 533 on the rod portion 531 can move toward or away from the stop 532. The outer rib 524 of the outer arm 52 can be located at the end of the cylindrical portion 533. The outer rib 524 can be bent from the outer bridging portion 523 toward the first inner rod 511 and the second inner rod 512 and opposite to the inner rib 514. A flange 533F can be formed at the end of the cylindrical portion 533 facing the outer rib 524 and support the outer rib 524.

[0055] The elastic member 534 can be located between the stop 532 and the cylinder 533, and can extend and retract along the length of the rod 531. The elastic member 534 can be a spring with elasticity. The elastic member 534 can be wound in the form of a coil around the stop 532 and the cylinder 533. One end of the elastic member 534 can be fixed to the flange 532F of the stop 532, and the other end of the elastic member 534 can be fixed to the flange 533F of the cylinder 533. Thus, the elastic member 534 can be gradually compressed as the cylinder 533 approaches the stop 532, and the elastic member 534 can gradually return to its original length as the cylinder 533 moves away from the stop 532.

[0056] Reference Figure 9 and Figure 10 The support arm 50 can be rotatably connected to the first bracket 61 and the second bracket 62 respectively.

[0057] The first bracket 61 can be connected to the rod 30 (see reference). Figure 2The upper end of the first bracket 61 is joined to the support arm 50 and is adjacent to one end of the support arm 50. The first bracket 61 may include a first side portion 611, a second side portion 612, and a bottom portion 613. The bottom portion 613 may form the bottom of the first bracket 61. The first side portion 611 may be bent upward from one side of the bottom portion 613, and the second side portion 612 may be bent upward from the other side of the bottom portion 613. The first side portion 611 and the second side portion 612 may be spaced apart from each other. A spacer 614 may be inserted between the first side portion 611 and the second side portion 612. The first bracket 61 may be made of HGI (hot rolled galvanized iron). The first bracket 61 may be referred to as a rear bracket 61, a hinge bracket 61, or a clip 61.

[0058] Furthermore, the first bracket 61 may be located between the inner rods 511 and 512 of the inner arm 51. The first bracket 61 may be located between the outer rods 521 and 522 of the outer arm 52. The first inner rod 511 and the first outer rod 521 may be adjacent to the left side of the first side portion 611, and the second inner rod 512 and the second outer rod 522 may be adjacent to the right side of the second side portion 612.

[0059] The first pin Pa can sequentially pass through the first hole 511a, the first side portion 611, the second side portion 612, and the first hole 512a of the second inner rod 512, and is engaged with the first inner rod 511 and the second inner rod 512. The inner arm 51 can be engaged with the first bracket 61 to be rotatable about the first pin Pa. For example, the first pin Pa can be fixed to the inner arm 51 by a rivet or nut and can rotate relative to the first bracket 61. For example, a washer and / or a disc spring can be engaged with the first pin Pa to provide friction for the rotation of the inner arm 51 relative to the first bracket 61.

[0060] The second pin Pb can sequentially pass through the first hole 521a, the first side portion 611, the second side portion 612 of the first outer rod 521, and the first hole 522a of the second outer rod 522, and engage with the first outer rod 521 and the second outer rod 522. The outer arm 52 can be engaged with the first bracket 61 to be able to rotate about the second pin Pb. For example, the second pin Pb can be fixed to the outer arm 52 by a rivet or nut and rotate relative to the first bracket 61. For example, a washer and / or a disc spring can be engaged with the second pin Pb to provide friction for the rotation of the outer arm 52 relative to the first bracket 61.

[0061] The central axis of the first pin Pa and the central axis of the second pin Pb can be separated from each other. The central axis of the second pin Pb can be separated from the central axis of the first pin Pa by an upward axis.

[0062] The second bracket 62 can be coupled to the rotary connector 40 and is adjacent to the other end of the support arm 50. The second bracket 62 may include a first side portion 621, a second side portion 622, and a body 623. The body 623 may form the rear portion of the second bracket 62. The body 623 may be a solid block (see figure). Figure 10 ) or "C" shaped bars (see reference) Figure 9 The first side portion 621 protrudes forward from one front end of the main body 623, and the second side portion 622 protrudes forward from the other front end of the main body 623. The first side portion 621 and the second side portion 622 can be spaced apart from each other. A portion of the rotary connector 40 can be inserted between the first side portion 621 and the second side portion 622. The second bracket 62 may include HGI (hot rolled galvanized iron) material. The second bracket 62 may be referred to as the front bracket 62.

[0063] Furthermore, the second bracket 62 can be located between the inner rods 511 and 512 of the inner arm 51. The second bracket 62 can be located between the outer rods 521 and 522 of the outer arm 52. The first inner rod 511 and the first outer rod 521 can be adjacent to the left side of the main body 623, and the second inner rod 512 and the second outer rod 522 can be adjacent to the right side of the main body 623.

[0064] The third pin Pc can sequentially pass through the second hole 511b of the first inner rod 511, the main body 623, and the second hole 512b of the second inner rod 512, and engage with the first inner rod 511 and the second inner rod 512. The inner arm 51 can be engaged with the second bracket 62 to be able to rotate about the third pin Pc. For example, the third pin Pc can be fixed to the inner arm 51 by a rivet or nut and rotate relative to the second bracket 62. For example, a washer and / or a disc spring can be engaged with the third pin Pc to provide friction for the rotation of the inner arm 51 relative to the second bracket 62.

[0065] The fourth pin Pd can sequentially pass through the second hole 521b of the first outer rod 521, the main body 623, and the second hole 522b of the second outer rod 522, and engage with the first outer rod 521 and the second outer rod 522. The outer arm 52 can be engaged with the second bracket 62 to be able to rotate about the fourth pin Pd. For example, the fourth pin Pd can be fixed to the outer arm 52 by a rivet or nut and rotate relative to the second bracket 62. For example, a washer and / or a disc spring can be engaged with the fourth pin Pd to provide friction for the rotation of the outer arm 52 relative to the second bracket 62.

[0066] The central axes of the third pin Pc and the fourth pin Pd can be separated from each other. The central axis of the fourth pin Pd can be separated from the central axis of the third pin Pc by an upward axis.

[0067] The second part 531b of the rod 531 can be located between the first side part 611 and the second side part 612 of the first bracket 61, and the rear end of the second part 531b, i.e. the end 531c of the rod 531, can be located behind the first bracket 61.

[0068] Refer again Figure 6 The support arm 50 may include an arm cover 54. The arm cover 54 may surround the inner arm 51, the outer arm 52, and the support member 53, and may form the surface of the support arm 50. A lower cover 541 may form the lower part of the arm cover 54, and an upper cover 542 may form the upper part of the arm cover 54. The lower cover 541 may be latched with the outer rods 521 and 522 of the outer arm 52, and the upper cover 542 may be latched with the lower cover 541.

[0069] The end 531c of the rod 531 can be fixed to the arm cover 54. The end 531c of the rod 531 can be covered by the rear portion of the arm cover 54. Alternatively, the end 531c of the rod 531 can also be exposed to the outside from the rear portion of the arm cover 54.

[0070] A portion of the first bracket 61 may be covered by the arm cover 54. At least a portion of the second bracket 62 may be covered by the arm cover 54. The ring body 480 of the retainer 47 coupled with the second bracket 62 may be covered by the arm cover 54.

[0071] Refer again Figure 9 and Figure 10 The inner arm 51 of the support arm 50 can rotate around the first pin Pa, and the outer arm 52 of the support arm 50 can rotate around the second pin Pb. The inner arm 51 can rotate around the third pin Pc, and the outer arm 52 can rotate around the fourth pin Pd. The inner arm 51, the outer arm 52, and the pins Pa, Pb, Pc, and Pd can be a four-section connecting rod connecting the first bracket 61 and the second bracket 62. The distance between the central axes of the first pin Pa and the second pin Pb can be the same as the distance between the central axes of the third pin Pc and the fourth pin Pd.

[0072] Therefore, regardless of the angle (tilt angle) at which the support arm 50 is tilted relative to the first bracket 61, the angle of the second bracket 62 relative to the horizontal line can remain constant. That is, the angle of the display 10 coupled to the second bracket 62 can remain constant regardless of the tilt angle of the support arm 50 (see reference). Figure 2 ).

[0073] The support member 53 can be connected to the inner arm 51 via the inner rib 514 and rotate together with the inner arm 51. The length of the elastic member 534 of the support member 53 can change with the rotation (tilt) of the support arm 50, and the support member 53 can provide a way to counteract the rotation of the display 10 (see reference). Figure 2The force exerted on the support arm 50 by the load is the torque. For example, the support arm 50 can tilt within a range of +25 degrees to -25 degrees, and corresponding to the tilt of the support arm 50, the height of the display 10 can be raised or lowered within a range of about 180 mm.

[0074] For example, the support arm 50 can rotate in the first rotation direction RD1 (see reference). Figure 9 Rotation. Correspondingly, the outer rib 524 of the outer arm 52 can move towards the inner rib 514 while pushing the cylindrical portion 533 towards the stop member 532. As a result, the elastic member 534 between the flange 533F of the cylindrical portion 533 and the flange 532F of the stop member 532 can be compressed. The force provided by the elastic member 534 can act as a torque attempting to rotate the support arm 50 in the opposite direction to the first rotation direction RD1. If this torque is balanced with the force attempting to rotate the support arm 50 in the first rotation direction RD1, the support arm 50 can remain in a downward tilted state.

[0075] For example, the support arm 50 can rotate in the second direction RD2 (see reference). Figure 9 The outer rib 524 of the outer arm 52 can move away from the inner rib 514. Consequently, the elastic member 534 between the flange 533F of the cylinder 533 and the flange 532F of the stop member 532 can be restored and stretched. The force provided by the elastic member 534 can act as a torque attempting to rotate the support arm 50 in the first rotation direction RD1. If this torque is balanced by a force attempting to rotate the support arm 50 in the second rotation direction RD2, the support arm 50 can remain in an upward tilted state.

[0076] The user can adjust the position of the flange 532F of the stop 532 by rotating the rod 531 using a tool such as a wrench that engages with the end 531c of the rod 531. If the user rotates the rod 531 in a first rotation direction R1, the stop 532 can move away from the inner rib 514, and the elastic member 534 can be further compressed. If the user rotates the rod 531 in a second rotation direction R2, the stop 532 can move towards the inner rib 514, and the compression of the elastic member 534 can be less.

[0077] Reference Figure 11 The front bracket 42 of the rotary connector 40 can be plate-shaped as a whole. The rotary connector 40 can be referred to as an articulated connector 40.

[0078] The pivot shaft 44 can extend in the front-rear direction. The diameter of the head 44a of the pivot shaft 44 can be larger than the diameter of the body 44b. A pair of cut-outs 44c can be formed on the side of the body 44b and face each other. A hole 42h in the front bracket 42 can be formed in the center of the front bracket 42 and penetrated by the body 44b. The shape of the hole 42h in the front bracket 42 can be the same as the shape of the longitudinal section of the body 44b. Thus, the pivot shaft 44 and the front bracket 42 can rotate together with respect to the axial direction of the pivot shaft 44. That is, the pivot shaft 44 can provide a pivot axis.

[0079] A front grab 45a can be located between the head 44a and the front of the front bracket 42. The hole 45ah of the front grab 45a can be aligned with the hole 42h of the front bracket 42 and has the same shape as the hole 42h. The body 44b can pass through the holes 45ah and 42h. The front grab 45a can be fixed to the front bracket 42. That is, the front grab 45a can rotate together with the pivot 44 and the front bracket 42.

[0080] Reference Figure 12 and Figure 13 The rear bracket 43 can be located behind the front bracket 42. The rear bracket 43 may include a mounting part 43F, a top wing 43L, and a bottom wing 43R.

[0081] Mounting portion 43F may face front bracket 42 and has a circular mounting hole 43Fh. At least one washer 43Fw may be located between front bracket 42 and mounting portion 43F and has a circular hole. The body 44b of pivot 44 may pass through the hole of washer 43Fw and mounting hole 43Fh, and may rotate independently of washer 43Fw and mounting portion 43F.

[0082] The upper wing 43L can extend rearward from the top of the mounting part 43F. The lower wing 43R can extend rearward from the bottom of the mounting part 43F. The plurality of components 45c (45c1, 45c2, 45c3, 45c4, 45c5) described later can be joined to the mounting part 43F between the upper wing 43L and the lower wing 43R.

[0083] The rear grab 45c1 can face the washer 43Fw across the mounting part 43F and has a circular hole 45ch through which the body 44b of the pivot 44 passes. The rear grab 45c1 can be fixed to the back of the mounting part 43F.

[0084] Furthermore, a plurality of fixing holes 45ca and a plurality of slots 45cb can be formed on the rear gripping portion 45c1 and spaced apart from each other in the circumferential direction of the rear gripping portion 45c1. The plurality of fixing holes 45ca and the plurality of slots 45cb can be arranged alternately in the circumferential direction of the rear gripping portion 45c1. For example, the fixing holes 45ca or the slots 45cb can be spaced apart from each other at 90-degree intervals. In the circumferential direction of the rear gripping portion 45c1, the length of the slot 45cb can be greater than the length of the fixing hole 45ca.

[0085] The disc 45c2 can be located behind the rear gripper 45c1 and has a hole 45c2h through which the body 44b passes and has the same shape as the longitudinal cross-section of the body 44b. A plurality of protrusions 45cc can protrude from the front of the disc 45c2 toward the rear gripper 45c1 and are spaced apart from each other in the circumferential direction of the disc 45c2. For example, the protrusions 45cc can be spaced apart at 90-degree intervals. The size of the protrusions 45cc can be the same as or correspond to the size of the fixing hole 45ca. That is, if the protrusions 45cc are inserted into the fixing hole 45ca, the rotation of the disc 45c2 and the pivot 44 can be restricted to a predetermined degree by the rear gripper 45c1. Furthermore, if the protrusions 45cc are inserted into the slot 45cb, the disc 45c2 and the pivot 44 can rotate within the trajectory of the slot 45cb.

[0086] Washer 45c3 may be located behind disk 45c2 and has a circular hole (not marked) through which the body 44b of pivot 44 passes.

[0087] The disc spring 45c4 can face the disc 45c2 through a washer 45c3 and has a circular hole (unmarked) through which the body 44b of the pivot 44 passes. The disc spring 45c4 can be elastic and can protrude forward or backward. The disc spring 45c4 can generate a spring force in the axial direction of the pivot 44.

[0088] The cap 45c5 can be located behind the disc spring 45c4 and has a hole 45c5h through which the main body 44b of the pivot 44 passes. The shape of the hole 45c5h can be the same as the shape of the longitudinal section of the main body 44b. The cap 45c5 can be fixed to the end of the main body 44b.

[0089] Therefore, pivot 44 can rotate together with front bracket 42, front grip 45a, disc 45c2, and cap 45c5. Alternatively, pivot 44 can rotate independently with washer 43Fw, rear bracket 43, rear grip 45c1, washer 45c3, and disc spring 45c4. In other words, even if pivot 44 rotates, washer 43Fw, rear bracket 43, rear grip 45c1, washer 45c3, and disc spring 45c4 can remain stationary.

[0090] In addition, the user can fix the monitor 10 (see below) to the front bracket 42. Figure 16 and Figure 10 The display 10 pivots relative to pivot 44. For example, the display 10 can pivot within a range of +90 degrees to -90 degrees. Furthermore, due to the elastic force of the aforementioned disc springs 45c41 and 45c42, the display 10 can maintain a predetermined pivot angle unless an external force exceeding a specified level is applied. Additionally, during the pivoting movement of the display 10, the user can feel a sense of tightness from the protrusion 45cc's engagement with the fixing hole 45ca or slot 45cb. That is, when the protrusion 45cc disengages from the slot 45cb and inserts into the fixing hole 45ca, the user can feel the display 10 at a pivot angle of 0 degrees, +90 degrees, or -90 degrees.

[0091] Reference Figure 14 The retainer 47 can be located between the upper wing 43L and the lower wing 43R. The retainer body 470 can cover the rear of the mounting portion 43F of the rear bracket 43. The first portion 47L can protrude from the upper part of the retainer body 470 toward the mounting portion 43F and is adjacent to the upper wing 43L. The second portion (see reference) Figure 12 )47R can protrude from the lower part of the retainer body 470 toward the mounting part 43F and is adjacent to the lower wing 43R.

[0092] The rotating shaft 46 can extend vertically. The rotating shaft 46 can pass through the upper wing 43L, the first portion 47L, the second portion 47R, and the lower wing 43R. A head (not marked) at one end of the rotating shaft 46 can be located on the side of the upper wing 43L. The other end of the rotating shaft 46 can be threaded, and a fastening member 46d, such as a nut, can be fastened to the other end of the rotating shaft 46 on the lower wing 43R.

[0093] Furthermore, the rotating shaft 46 can be integrally cylindrical and fixed to the upper wing 43L and the lower wing 43R. The rotating shaft 46 can be rotatably coupled to the retainer 47. That is, the rotating shaft 46 can provide a rotation axis (axis of rotation). At least one washer 46v can be located between the second part 47R and the lower wing 43R and has a circular hole through which the rotating shaft 46 passes.

[0094] The elastic member 46a can be located between the upper wing 43L and the lower wing 43R. The elastic member 46a can be wound multiple times around the outer circumference of the rotating shaft 46 and has elasticity. The elastic member 46a can be a coil-shaped spring.

[0095] Furthermore, a portion 46b of the elastic member 46a can extend in a direction intersecting the rotation axis 46 without being wrapped around the rotation axis 46. A portion 46b of the elastic member 46a can be engaged with a support portion 43h that protrudes rearward from the mounting portion 43F.

[0096] Additionally, one end of the elastic member 46a may be formed in the portion 46b, and the other end of the elastic member 46b may be fixed to the inside of the retainer 47. A disc spring 46w may be adjacent to the other end 46c of the elastic member 46a and located between the elastic member 46a and the second portion 47R. The disc spring 46w may have a circular hole (not marked) through which the rotation shaft 46 passes. The disc spring 46w may protrude toward the elastic member 46a and generate a spring force in the axial direction of the rotation shaft 46.

[0097] Thus, the rotation axis 46 can rotate together with the rear bracket 43, the front bracket 42, and a plurality of components 45c5, 45c4, 45c3, 45c2, 45c1, 43Fw, 45a, and 44. Corresponding to this rotation of the rotation axis 46, the display 10 (see below) fixed to the front bracket 42... Figure 16 and Figure 10 It can rotate left and right. For example, the display 10 can rotate within the range of +45 degrees to -45 degrees.

[0098] On the other hand, pin 47P can be fixed to the first portion 47L and / or the second portion 47R. For example, pin 47P can protrude upward from the side of the first portion 47L. A guide groove 43g can be formed by recessing forward from the rear end of the upper wing 43L. A reference point 43ga can be located in the display 10 (see below). Figure 16 and Figure 10 The shaft 46 is in contact with pin 47P without tilting to the left or right. The right groove 43gb can be formed by drawing an arc from the reference point 43ga along the first rotation direction. The left groove 43gc can be formed by drawing an arc from the reference point 43ga in the second rotation direction opposite to the first rotation direction. The rotation of the rotating shaft 46 can be restricted by pin 47P engaging either the right groove 43gb or the left groove 43gc.

[0099] Reference Figure 15 The ankle 471 of the retainer 47 can connect the retainer body 470 and the rotating unit 48 of the retainer 47. The rotating unit 48 can be referred to as the rotating body 48 or the tilting unit 48. The ankle 471 can be referred to as the connecting part 471.

[0100] The rotating unit 48 may include a ring body 480, a shaft 48a, a first fixing washer 48b, a disc spring 48d, a first washer 48e, a first bushing 48f, a second bushing 48g, a second washer 48h, and a second fixing washer 48c.

[0101] The ring body 480 may open to the left or right. The ring body 480 may be in the shape of a donut as a whole. For example, the ring body 480 may be formed integrally with the ankle 471. The ring body 480 may be inserted between the first side portion 621 and the second side portion 622 of the second bracket 62.

[0102] Shaft 48a can extend in the left-right direction. Shaft 48a can pass through a hole 480h formed in the center of the ring body 480. Shaft 48a can be a fastening member such as a bolt. Shaft 48a can be fastened to the first side portion 621, and the head 48ah of shaft 48a can be engaged in the second side portion 622.

[0103] The first retaining washer 48b may be located below the head 48ah of the shaft 48a and be penetrated by the shaft 48a. The first retaining washer 48b may be a toothed lock washer, and the teeth 48bt of the first retaining washer 48bb may be inserted into and secured in a groove (not marked) formed on the inner side of the second side portion 622.

[0104] The disc spring 48d can be located below the first retaining washer 48b. The disc spring 48d can protrude toward the first retaining washer 48b and generate elastic force in the axial direction of the shaft 48a.

[0105] The first washer 48e can be located below the disc spring 48d and is penetrated by the shaft 48a.

[0106] The first bushing 48f may face the disc spring 48d through the first washer 48e. The shaft 48a may pass through the first bushing 48f. The first bushing 48f may be cylindrical in shape with a flange (unmarked) formed at its upper end. The flange of the first bushing 48f may contact a first upper groove 480a formed on the top surface of the ring body 480 along the periphery of the hole 480h. A portion (unmarked) of the first bushing 48f may be inserted into the hole 480h of the ring body 480 and located between the inner circumferential surface of the ring body 480 and the outer circumferential surface of the shaft 48a.

[0107] The second bushing 48g may face the first bushing 48f and be spaced to the left from the first bushing 48f. The shaft 48a may pass through the second bushing 48g. The second bushing 48g may be cylindrical with a flange (unmarked) formed at its lower end. The flange of the second bushing 48g may contact a first lower groove 480b formed on the bottom surface of the ring body 480 along the hole 480h. A portion (unmarked) of the second bushing 48g may be inserted into the hole 480h of the ring body 480 and located between the inner circumferential surface of the ring body 480 and the outer circumferential surface of the shaft 48a.

[0108] The second washer 48h can be located below the second bushing 48g and is penetrated by the shaft 48a.

[0109] The second retaining washer 48c can face the second bushing 48g through the second washer 48h and be penetrated by the shaft 48a. The second retaining washer 48c can be a toothed lock washer, and the teeth 48ct of the second retaining washer 48c can be inserted into and fixed in the groove (not marked) formed on the inner side of the first side portion 621.

[0110] Therefore, the ring body 480 can rotate relative to the shaft 48a fixed to the second bracket 62. That is, the shaft 48a can provide a tilting axis. In addition, due to the elastic force of the aforementioned disc spring 48d, the display 10 can maintain its tilt angle unless an external force above a specified level is applied. For example, the display 10 can tilt within the range of +65 degrees to -65 degrees.

[0111] The groove 480g can be formed in an arc shape at the rear of the ring body 480. The protrusion 624 can protrude from the body 623 of the second bracket 62 toward the groove 480g. If one end or the other end of the groove 480g contacts the protrusion 624, the rotation of the ring body 480 can be restricted.

[0112] Reference Figure 16 , Figure 10 as well as Figure 14 The recess 41 can be formed by recessing forward from the back cover 15 of the display. The recess 41 may include a first recess 410 and a second recess 411. The first recess 410 can be formed by recessing backward from the back of the back cover 15. The second recess 411 can be formed by recessing forward from the back of the first recess 410, and forms the central portion of the recess 41.

[0113] The lower hole 41b can be formed through the second recess 411 and is located below the center of the recess 41. The lower hole 41b can be formed in the lower part of the second recess 411 and is located at the boundary between the second recess 411 and the first recess 410. The first engaging part 1831a can be located in the first lower hole 41b1, and the second engaging part 1832a can be located in the second lower hole 41b2.

[0114] A top hole 41a can be formed through the second recess 411 and is located above the center of the recess 41. The top hole 41a can be formed in the upper part of the second recess 411 and is located at the boundary between the second recess 411 and the first recess 410. In the vertical direction, the first top hole 41a1 can be aligned with the first lower hole 41b1, and the second top hole 41a2 can be aligned with the second lower hole 41b2.

[0115] The top protrusion 42a can protrude upward from the upper side of the front bracket 42. The first top protrusion 42a1 can be adjacent to the left side of the front bracket 42. The second top protrusion 42a2 can be adjacent to the right side of the front bracket 42.

[0118] The first lower protrusion 42b1 can correspond to the first lower hole 41b1. The first lower protrusion 42b1 can engage with the first engaging part 1831a. The second lower protrusion 42b2 can correspond to the second lower hole 41b2. The second lower protrusion 42b2 can engage with the second engaging part 1832a.

[0119] The first protruding portion 42a1 can correspond to the first top hole 41a1. The first protruding portion 42a1 can engage with the first top hole 41a1. The second protruding portion 42a2 can correspond to the second top hole 41a2. The second protruding portion 42a2 can engage with the second top hole 41a2.

[0120] Thus, the rotary connector 40, which is coupled with the second bracket 62, can be detachably coupled with the display 10.

[0121] Cover 40c may cover the rear of rotary connector 40 and be coupled to display 10. Inner cover 40c1 may be fixed to the rear of rotary connector 40 and form the central portion of cover 40c. Inner cover 40c1 may be located behind retainer body 470 of retainer 47. Inner cover 40c1 may be located between retainer body 470 and ring body 480 of retainer 47. Outer cover 40c2 may extend along the periphery of inner cover 40c1 and be fixed to recess 41 of rear cover 15. Thus, outer cover 40c2 may pivot relative to inner cover 40c1 together with display 10.

[0122] A cover hole 40h can be formed in the inner cover 40c1, and the cover hole 40h can be a slot shape that is longer in the lateral direction, corresponding to the left and right rotation (i.e., rotation) of the aforementioned display 10 around the rotation axis 46. That is, the cover hole 40h can be formed elongated along the rotation direction of the display 10 around the rotation axis 46. The ankle portion 471 of the retainer 47 can be located in the cover hole 40h. As the display 10 rotates left and right, the ankle portion 471 of the retainer 47 can be close to one end or the other end of the cover hole 40h. The cable electrically connected to the display 10 can pass through the cover hole 40h.

[0123] A slot 54h can be formed in the arm cover 54, and the slot 54h can be vertically elongated in shape to correspond to the up-and-down rotation (i.e., tilting) of the aforementioned display 10 around axis 48a. One end of the arm cover 54 can be curved, and the slot 54h can be formed elongated along the rotational trajectory of the ankle 471 at said end of the arm cover 54. As the display 10 rotates up and down, the ankle 471 of the retainer 47 can be close to one end or the other end of the slot 54h. Cables electrically connected to the display 10 can pass through the slot 54h.

[0124] The end of the arm cover 54 facing the cover 40c may be adjacent to and spaced apart from the inner cover 40c1. The ankle 471 of the retainer 47 may be located between the end of the arm cover 54 and the inner cover 40c1. The transverse elongated hole 40h of the cover 40c and the vertical elongated slot 54h of the arm cover 54 may extend in directions that intersect each other.
