The support groove 134 may be formed to engage and couple with the link support portion 115. As an example, the support groove 134 may be formed on the lower side of the hinge link 130 and may be formed to have a concave recessed shape upward from the lower side of the hinge link 130.

The link support portion 115 may be inserted into the support groove 134 in the vertical direction in the Z direction and engaged with the support groove 134.

As the link support portion 115 and the support groove 134 engage with each other, the hinge link 130 may be supported by the body bracket 110 and may be restricted from moving in the X direction to the Z direction.

As an example, the hinge link 130 may be made of a metal material. However, the material of the hinge link 130 is not limited to this.

The hinge link 130 described above is only an example of a configuration provided to connect the main body bracket and the door bracket in the hinge assembly of a cooking appliance according to the spirit of the present disclosure, and the spirit of the present disclosure is not limited thereto. .

Meanwhile, the hinge assembly 100 may include an elastic system that allows the door 30 to efficiently rotate when the door 30 opens or closes the cooking compartment 20 .

As an example, the elastic system of the hinge assembly 100 may include a first elastic member 150.

The first elastic member 150 is configured to accumulate elastic force when the door 30 opens the galley 20 and to provide elastic force when the door 30 closes the galley 20. It is possible to compensate for the fact that the door 30 does not close easily due to its own weight.

In detail, the first elastic member 150 may include a first elastic spring 151 provided to accumulate or provide elastic force, and a first spring rod 152 supported by the door bracket 120. The first elastic spring 151 may be arranged to surround the outer peripheral surface of the first spring rod 152.

The first elastic member 150 may be supported by the door bracket 120. The first elastic member 150 may be accommodated inside the door bracket 120.

Additionally, as an example, the elastic system of the hinge assembly 100 may include a second elastic member 160.

The second elastic member 160 is configured to provide elastic force in the direction in which the door 30 is opened in the initial stage of the operation of opening the galley 20 from the closed position of the door 30, so that the door 30 is easily opened. It can be arranged so that it can be opened freely. In addition, the second elastic member 160 may function as a damper that prevents the door 30 from closing too quickly when the door 30 closes the cooking chamber 20.

In detail, the second elastic member 160 includes a second elastic spring 161 provided to accumulate or provide elastic force, a second spring rod 162 supported on the door bracket 120, and a hinge link 130. ) may include a roller 163 in contact with the

The second elastic spring 161 may be arranged to surround the outer peripheral surface of the second spring rod 162.

The roller 163 may be coupled to the second spring rod 162. The roller 163 is in contact with the outer surface of the hinge link 130 and may be provided to be movable on the outer surface of the hinge link 130 according to the rotational movement of the door 30. That is, the contact structure between the roller 163 and the hinge link 130 may be configured as a cam structure. Depending on the movement of the roller 163, the degree of elastic force accumulated in the second elastic spring 161 may vary.

As an example, the roller 163 may be in contact with the upper side of the hinge link 130.

The second elastic member 160 may be supported by the door bracket 120. The second elastic member 160 may be accommodated inside the door bracket 120.

However, unlike what was described above, the hinge assembly 100 may not have an elastic system such as the first elastic member 150 and the second elastic member 160, and may have an elastic structure modified to perform a similar function. You can also have a system.

With the above configuration, the hinge assembly 100 can connect the door 30 and the main body 10 and rotatably support the door 30.

On the other hand, the parts of the hinge assembly 100 may be separated from each other or moved from the designed position due to vibration occurring in the process of transporting the finished product, vibration occurring in the process of opening and closing the product door, or vibration caused by other external shocks. Problems with separation may occur.

Therefore, in the hinge assembly 100 of the cooking appliance 1 according to an embodiment of the present disclosure, the door bracket 120 to the hinge link 130 can be stably coupled to the main body bracket 110, and ultimately the door A structure may be required to stably support (30) and enable the door (30) to be stably assembled to the main body (10).

The hinge assembly 100 may include a locking member 140 that is provided to fix the position of the door bracket 120 when the door 30 closes the cooking compartment 20. The locking member 140 may be provided to prevent the door bracket 120 to the hinge link 130 from being separated from the main body bracket 110.

Hereinafter, the structure and function of the locking member 140 will be described in detail.

Figure 5 is an enlarged view of a portion of Figure 4. Figure 6 is a diagram showing the movement of the locking member in the hinge assembly of Figure 5. FIG. 7 is a diagram illustrating a locking member included in the hinge assembly of a cooking appliance according to an embodiment of the present disclosure.

5 to 7, the locking member 140 may be coupled to the hinge link 130. The locking member 140 may maintain a fixed position relative to the hinge link 130 regardless of the rotational movement of the door 30. Furthermore, because the hinge link 130 is fixed to the main body bracket 110, the locking member 140 can maintain a fixed position with respect to the main body bracket 110 regardless of the rotational movement of the door 30.

The locking member 140 may be coupled to the hinge link 130 by a coupling shaft 182. The coupling shaft 182 may penetrate the locking member 140 and the hinge link 130. For example, the coupling shaft 182 may extend in the Y direction and penetrate the locking member 140 and the hinge link 130 in the Y direction.

The locking member 140 may include a locking body 141. The locking body 141 may be coupled to the hinge link 130.

The locking body 141 may cover at least a portion of the hinge link 130. For example, the locking body 141 may cover at least a portion of the hinge link 130 in the left and right directions in the Y direction.

For example, as shown, when the door 30 is in a position to close the cooking compartment 20, part of the locking body 141 may be covered by the door bracket 120. In this case, a portion of the locking body 141 may cover the door coupling portion 132 of the hinge link 130.

The coupling shaft 182 may be provided on the locking body 141. The coupling shaft 182 may penetrate the locking body 141 and the hinge link 130 to couple the locking member 140 and the hinge link 130.

For example, the coupling shaft 182 may be covered by the door bracket 120 when the door 30 is in a position to close the cooking compartment 20. The coupling shaft 182 may penetrate the door coupling portion 132 of the hinge link 130.

The locking member 140 may be rotatable about the hinge link 130 about the coupling axis 182.

Even though the locking member 140 can maintain a fixed position with respect to the hinge link 130 regardless of the rotational movement of the door 30, the locking member 140 is centered on the hinge link 130 around the coupling axis 182. ) can be provided to be rotatable about.

For example, in the manufacturing step of the hinge assembly 100 or the step of mounting the hinge assembly 100 to the main body 10 to the door 30, the locking member 140 is connected to the hinge link 130 for convenience of manufacturing. A rotatable structure may be required.

When the manufacturing step of the hinge assembly 100 or the step of mounting the hinge assembly 100 to the main body 10 to the door 30 is completed, the locking member 140 is attached to the main body bracket 110 as shown in FIG. 5. ) can be supported by.

Meanwhile, taking the locking member 1140 of the hinge assembly 1100 of the embodiment shown in FIGS. 17 to 19 as an example, the locking member 1140 is efficiently moved in the X direction by the main body bracket 1110 of the hinge assembly 1100. However, there may be a problem in that it cannot be effectively supported in the Z direction or in the direction in which the locking member 1140 rotates with respect to the hinge link 1130.

As described above, since the locking member 140 is not completely fixed to the hinge link 130, vibration occurring during the transport of the finished product, vibration occurring during the process of opening and closing the door of the product, When movement of the locking member 140 relative to the hinge link 130 occurs due to vibration caused by other external shocks, etc., there is a risk that the locking member 140 may be separated from the position supported by the main body bracket 110.

In particular, this is the height in the Z direction of the coupling axis 182 where the locking member 140 and the hinge link 130 are coupled and the height in the Z direction of the point where the locking member 140 is supported on the main body bracket 110. If there is a difference, it can be even more problematic.

In the embodiment shown in FIGS. 5 to 7, the locking member 140 may be engaged with the main body bracket 110. In this case, the locking member 140 may be supported not only in the Accordingly, the locking member 140 can be more stably supported relative to the main body bracket 110, and the position of the door bracket 120 can be more stably fixed when the door 30 closes the galley 20. there is.

The locking member 140 is engaged with the main body bracket 110 and can maintain a fixed position with respect to the main body bracket 110. That is, the locking member 140 can maintain a constant position regardless of the rotational movement of the door 30.

In detail, the locking member 140 may include a locking portion 142 that is engaged with the main body bracket 110. As the locking portion 142 is hooked to the main body bracket 110, the door bracket 120 to the hinge link 130 can be prevented from being separated from the main body bracket 110, and the door 30 can be stored in the galley ( When closing 20), the position of the door bracket 120 can be fixed.

The body bracket 110 may include an insertion portion 114 into which at least a portion of the engaging portion 142 is inserted. At least a portion of the engaging portion 142 may be inserted into the insertion portion 114 and engaged with the main body bracket 110 .

The locking portion 142 may protrude from the locking body 141 toward the inside of the insertion portion 114 so that at least a portion of the locking portion 142 can be inserted into and locked with the insertion portion 114 .

As the locking part 142 is inserted into the insertion part 114, the locking member 140 can be firmly fixed to the main body bracket 110, and the position of the door bracket 120 with respect to the main body bracket 110 can be adjusted. It can be fixed efficiently.

The insertion portion 114 may be provided at one end of the main body bracket 110 adjacent to the door bracket 120. The insertion portion 114 has a shape that is concavely depressed from one end adjacent to the door bracket 120 of the cover portion 111 in the direction opposite to the door bracket 120 (rearward in the X direction, based on the drawing). can be formed.

The insertion portion 114 may be formed to communicate with the receiving space 116 (see FIG. 11) inside the main body bracket 110. That is, the interior of the main body bracket 110 may be formed as an integrated space where the insertion portion 114 and the receiving space 116 are not separated from each other. However, the present invention is not limited to this, and the internal space of the main body bracket 110 may be formed so that the insertion portion 114 and the receiving space 116 are partitioned from each other.

Meanwhile, as described above, since the locking member 140 is not completely fixed to the hinge link 130, there is vibration occurring during the transportation of the finished product or vibration occurring during the process of opening and closing the door of the product. , there is a problem in which the locking portion 142 of the locking member 140 is separated from the main bracket 110 due to vibration caused by other external shocks (for example, when the locking member 140 rotates in the direction shown in FIG. 6 ). case, etc.) is likely to occur.

To prevent this problem, the locking member 140 may include a separation prevention portion 143. The separation prevention portion 143 may be provided to prevent the locking portion 142 from being separated from the main body bracket 110.

Specifically, the separation prevention part 143 may be provided to prevent the locking part 142 from being separated from the main body bracket 110 by interfering with the door bracket 120.

When the door 30 is positioned to close the cooking compartment 20, the separation prevention portion 143 may be disposed between the door bracket 120 and the locking portion 142.

When the door 30 closes the galley 20, the distance d1 between the door bracket 120 and the main body bracket 110 is one end in the direction of insertion into the insertion portion 114 of the locking portion 142 and It may be provided to be shorter than the distance d2 between one end of the separation prevention portion 143 that interferes with the door bracket 120. The distance d1 between the door bracket 120 and the main body bracket 110 here refers to the part of the door bracket 120 that may interfere with the separation prevention part 143 and the cover part adjacent to the insertion part 114. It means the distance measured in the X direction between parts of (111). In addition, the distance d2 between the one end of the locking portion 142 in the direction inserted into the insertion portion 114 and the end of the separation prevention portion 143 that interferes with the door bracket 120 is the locking portion 142. ) refers to the distance measured in the

The locking member 140 has a first position (see FIG. 5) where the locking part 142 is maximally inserted into the insertion part 114, and a position where the locking part 142 is separated from the insertion part 114 at the first position. It may be arranged to be positioned between the second positions (see FIG. 6) moved in the direction. The first and second positions of the locking member 140 may be defined as relative positions with respect to the body bracket 110 to the hinge link 130.

As an example, the locking member 140 may be rotatable between a first position and a second position about the coupling axis 182. When the locking member 140 moves between the first position and the second position, the locking portion 142 may move approximately along an arc centered on the coupling axis 182.

The escape prevention portion 143 may be provided to contact the door bracket 120 when the door 30 closes the cooking compartment 20 and the locking member 140 is located in the second position. That is, the separation prevention unit 143 may be provided to interfere with the door bracket 120 when the locking member 140 reaches the second position.

Conversely, the separation prevention part 143 may be arranged to be spaced apart from the door bracket 120 when the locking member 140 is in the first position. If the departure prevention part 143 always interferes with the door bracket 120 when the door 30 is closed, the door bracket 120 is This is because a collision may occur between (120) and the separation prevention unit 143, which may cause noise or vibration and damage to parts.

With this configuration, even if the locking part 142 moves in the direction away from the insertion part 114, the separation prevention part 143 is connected to the door bracket before the locking part 142 is completely separated from the insertion part 114. (120) may be interfered with.

The separation prevention portion 143 may be formed to protrude from the locking body 141 so that it can interfere with the door bracket 120 even if the locking member 140 rotates at only a small angle about the coupling axis 182. As an example, the separation prevention part 143 may protrude from the locking body 141 in a direction opposite to the main body bracket 110.

The distance from the coupling shaft 182 to the separation prevention portion 143 may be shorter than the distance from the coupling shaft 182 to the locking portion 142. In this case, even if the length of the separation prevention unit 143 protruding from the locking body 141 is not designed to be excessively long, the separation prevention unit 143 may move only a short distance and interfere with the door bracket 120. In addition, even if the protruding length of the locking portion 142 from the locking body 141 is not designed to be excessively long, the locking portion 142 can be effectively prevented from being separated from the insertion portion 114.

The separation prevention portion 143 may extend in a direction away from the door bracket 120 from the tip 143e that contacts the door bracket 120 in the second position when the door 30 closes the cooking compartment 20. . When the tip 143e of the separation prevention part 143 contacts the door bracket 120, the tip 143e and the door bracket 120 may contact to approximate a line contact.

With this configuration, unnecessary interference between the separation prevention unit 143 and the door bracket 120 is prevented, and the load applied to the separation prevention unit 143 can be distributed.

At this time, as the length at which the tip 143e of the separation prevention part 143 protrudes from the locking body 141 toward the door bracket 120 increases, the distance between the first and second positions of the locking member 140 increases. It can be shortened.

The tip 143e of the separation prevention part 143 may be provided on a side adjacent to the coupling axis 182 of the separation prevention part 143. In this case, even if the locking member 140 rotates only by a small angle about the coupling axis 182, the interference locking portion 142 can be prevented from being separated from the insertion portion 114.

The locking member 140 may include an extension portion 141a extending from the separation prevention portion 143 to the locking portion 142. The extension portion 141a may be a part of the locking body 141.

As shown in FIG. 7, the separation prevention part 143 of the locking member 140 may include a plurality of separation prevention parts 143a and 143b arranged to be spaced apart from each other.

When the locking member 140 is in the second position and the door 30 is in a position to close the cooking compartment 20, the plurality of separation prevention parts 143a and 143b may interfere with the door bracket 120, respectively.

As an example, the plurality of separation prevention parts 143a and 143b may be arranged to be spaced apart from each other in the Y direction.

As an example, the plurality of separation prevention parts 143a and 143b may be formed to have shapes and sizes that correspond to each other.

The locking member 140 may include a plurality of extension parts 141aa and 141ab extending from each of the plurality of separation prevention parts 143a and 143b to the locking part 142.

Each of the plurality of extension parts 141aa and 141ab may be a part of the locking body 141.

The plurality of extension parts 141aa and 141ab may be arranged to be spaced apart from each other. As an example, the plurality of extension parts 141aa and 141ab may be arranged to be spaced apart from each other in the Y direction.

As an example, the plurality of extension parts 141aa and 141ab may be formed to have shapes and sizes that correspond to each other.

The locking portion 142 may connect the plurality of extension portions 141aa and 141ab to each other. As an example, the plurality of extension parts 141aa and 141ab may be respectively connected to both ends of the locking part 142 in the Y direction.

As shown in FIG. 7, the locking portion 142, the separation prevention portion 143, and the extension portion 141a of the locking member 140 may be formed integrally. For example, the locking member 140 may be formed by bending both ends connected to the plurality of extension portions 141aa and 141ab of the locking portion 142, respectively.

Furthermore, the locking member 140 may be formed as a whole.

As an example, the locking member 140 may be made of a metal material. However, the material of the locking member 140 is not limited to this.

For example, as shown in FIG. 11, the method of manufacturing the hinge assembly 100 of the cooking appliance 1 according to an embodiment of the present disclosure involves connecting the body coupling portion 131 of the hinge link 130 to the body bracket 110. ) may include entering the inside of the receiving space 116 through the coupling hole 112 and coupling the hinge link 130 and the body bracket 110. At this time, the direction in which the main body coupling portion 131 penetrates the coupling hole 112 and enters the receiving space 116 may be parallel to the front-back direction in approximately the X direction with respect to the cooking appliance 1.

Meanwhile, the width (for example, the width in the Y direction) within the receiving space 116 of the main body bracket 110 is the width of the main body coupling portion 131 accommodated in the receiving space 116 (the previously mentioned receiving space 116). It can be assumed that the width is wider in the same direction as the inner width (for example, the width in the Y direction). In this case, the hinge link 130 may not be fixed to the body bracket 110 in the width direction within the receiving space 116, and the hinge link 130 may be fixed to the body bracket 110 in the width direction within the receiving space 116. It may be possible to flow in either direction. At this time, the main body bracket 110 will maintain a fixed position with respect to the main body 10, and the hinge link 130 will maintain a fixed position with respect to the door bracket 120, so that the main body 10 of the door 30 The relative position may be flexible.

Because of this, for example, if the door 30 moves in the Y direction from its designed position, the door 30 and the control panel 41 are not arranged side by side, which may cause a problem that deteriorates the external quality of the product. You can.

To solve this problem, the body bracket 110 may include a protrusion 113 provided to prevent the hinge link 130 from moving. The protrusion 113 may be formed to protrude toward at least a portion of the hinge link 130 accommodated in the body bracket 110. In other words, the protrusion 113 may protrude toward the body coupling portion 131 accommodated in the receiving space 116 of the body bracket 110.

The protrusion 113 may be provided inside the body bracket 110. The protrusion 113 may protrude from the cover part 111. The protrusion 113 may protrude from the cover part 111 toward the inside of the receiving space 116. The protrusion 113 may protrude from the cover portion 111 toward at least a portion of the hinge link 130 (that is, the body coupling portion 131) accommodated in the receiving space 116.

The protrusion 113 may support the hinge link 130. In detail, the protrusion 113 is in contact with the main body coupling portion 131 of the hinge link 130, and may support the hinge link 130 so that the hinge link 130 does not move with respect to the main body bracket 110. . That is, the protrusion 113 may restrict the movement of the hinge link 130 so that the hinge link 130 does not move relative to the main body bracket 110.

Since the protrusion 113 is provided to constrain the movement of the hinge link 130 after the hinge link 130 is coupled to the body bracket 110, the coupling step of the hinge link 130 and the body bracket 110 It is possible to restrain the hinge link 130 from moving in a direction different from the direction in which the main body coupling portion 131 is introduced into the main body bracket 110.

When the door bracket 120 and the body bracket 110 are arranged to face each other in the first direction, the protrusion 113 is provided to prevent the hinge link 130 from moving in a second direction different from the first direction. You can. The protrusion 113 may protrude from the cover portion 111 in a direction parallel to the second direction and may support the hinge link 130 in a direction parallel to the second direction.

Here, the first direction may be parallel to the direction in which the main body coupling portion 131 is introduced into the main body bracket 110 in the step of coupling the hinge link 130 and the main body bracket 110. Additionally, the first direction may be parallel to the direction in which the main body 10 and the door 30 face each other. Additionally, the first direction may be parallel to the front-to-back direction of the cooking appliance 1.

Here, the second direction may be parallel to the direction in which the pair of side plates of the cover portion 111 face each other. Additionally, the second direction may be parallel to the direction in which the plurality of hinge assemblies 100a and 100b (see FIG. 2) are arranged. Additionally, the second direction may be parallel to the direction of the rotation axis of the door 30. Additionally, the second direction may be parallel to the door 30 and the left and right directions of the cooking appliance 1.

More specifically, the first direction and the second direction may be perpendicular to each other. For example, based on the drawing, the first direction may be the X direction (front and rear direction of the cooking appliance 1) and the second direction may be the Y direction (left and right directions of the cooking appliance 1). As shown in FIGS. 11 to 13, the protrusion 113 may restrict movement of the hinge link 130 in the Y direction.

However, the second direction in which the protrusion 113 restrains the movement of the hinge link 130 is not limited to what has been described above, and is determined by the shape or size of the inside of the body bracket 110 or the body coupling portion 131 of the hinge link 130. ) may vary depending on the shape or size, etc.

Hereinafter, for convenience of explanation, the description will be based on an embodiment in which the first direction is parallel to the front-back direction of the cooking appliance 1, and the second direction is parallel to the left-right direction of the cooking appliance 1.

As an example, the protrusion 113 may include a pair of protrusions 113 disposed to face each other. The distance between the pair of protrusions 113 may correspond to the thickness of at least a portion of the hinge link 130 accommodated in the body bracket 110, that is, the thickness of the body coupling portion 131.

As an example, the pair of protrusions 113 may be arranged in the Y direction of the cooking appliance 1. That is, the pair of protrusions 113 may be arranged in the left and right directions of the main body 10. A pair of protrusions 113 may be arranged to face each other in the Y direction.

At this time, one protrusion of the pair of protrusions 113 may contact the left side of the hinge link 130, and the other protrusion of the pair of protrusions 113 may contact the right side of the hinge link 130. there is.

However, the number of protrusions 113 provided on the main body bracket 110 is not limited to this. For example, the main body bracket 110 may be provided with only a single protrusion or three or more protrusions.

With the above configuration, the body bracket 110 of the hinge assembly 100 includes the protrusion 113 to prevent the hinge link 130 from moving relative to the body bracket 110.

However, if the inner space of the main body bracket 110 is narrowed to correspond to the thickness of the main body coupling portion 131 from the portion adjacent to the coupling hole 112, or the inner space of the main body bracket 110 is formed entirely in the main body coupling portion ( If it is formed to correspond to the thickness of the hinge link 130 and the body bracket 110, it may not be easy for the body coupling portion 131 to be inserted into the body bracket 110 in the step of coupling the hinge link 130 and the body bracket 110.

Therefore, the receiving space 116 inside the main body bracket 110 has a width wider than the thickness of the main body coupling part 131 in the area near the coupling hole 112, which is the part where the main body coupling part 131 begins to be inserted. , It may be preferable that the portion located rearward from the coupling hole 112 in the

In other words, the protrusion 113 may be arranged to be spaced apart from one end of the cover part 111 on the door bracket 120 side (that is, one end of the cover part 111 where the coupling hole 112 is formed). In detail, the protrusion 113 may be disposed rearward than one end of the cover portion 111 on the door bracket 120 side in the X direction. The protrusion 113 may be disposed rearward of the coupling hole 112 in the X direction.

One end of the cover portion 111 on the door bracket 120 side may be arranged to be spaced apart from the hinge link 130. Additionally, at least a portion of the cover part 111 located between one end of the cover part 111 on the door bracket 120 side and the protrusion 113 may be spaced apart from the hinge link 130 . With this configuration, the body coupling portion 131 can be easily inserted into the body bracket 110 during the coupling step of the hinge link 130 and the body bracket 110.

The protrusion 113 may include a first inclined surface 113a. The first inclined surface 113a may be provided inside the main body bracket 110.

The first inclined surface 113a may extend to protrude inward in the Y direction of the receiving space 116 as it moves rearward in the X direction. The first inclined surface 113a may extend obliquely in the front-back direction of the cooking appliance 1.

The protrusion 113 may include a second inclined surface 113b extending in a different direction from the first inclined surface 113a. The second inclined surface 113b may be provided inside the main body bracket 110.

The second inclined surface 113b may extend to become farther away from the hinge link 130 as the distance from the door bracket 120 increases. The length of the second inclined surface 113b protruding from the cover part 111 becomes shorter as the distance from the door bracket 120 increases, and the second inclined surface 113b may extend away from the main body coupling portion 131 of the hinge link 130. The second inclined surface 113b may be extended so that the extent to which it protrudes inward in the Y direction of the receiving space 116 becomes shorter as it moves rearward in the X direction. The second inclined surface 113b may extend obliquely in the front-back direction of the cooking appliance 1.

The protrusion 113 may include a contact surface 113c in contact with the hinge link 130. The contact surface 113c is provided on the inside of the main body bracket 110 and can be in contact with the main body coupling portion 131.

The contact surface 113c may be provided between the first inclined surface 113a and the second inclined surface 113b. The contact surface 113c may support the hinge link 130 and restrict the movement of the hinge link 130. The contact surface 113c may distribute the load that the protrusion 113 receives from the hinge link 130.

The contact surface 113c extends in a direction approximately parallel to the X direction, or at least the extension direction of the contact surface 113c is inclined at an angle relative to the It may be extended to be smaller than the inclined angle.

As an example, the protrusion 113 may be formed to have an overall convex curved shape. As shown in FIGS. 11 to 13, the first inclined surface 113a, the second inclined surface 113b, and the contact surface 113c may each be formed in the shape of a convex curved surface toward the hinge link 130. In this case, the contact surface 113c can more efficiently distribute the load that the protrusion 113 receives from the hinge link 130.

For example, the protrusion 113 may be formed so that the length in the Z direction is longer than the length in the X direction. However, it is not limited to this, and the protrusion 113 may have various lengths depending on the direction.

As an example, the protrusion 113 may be formed integrally with the cover portion 111.

As an example, the protrusion 113 may be manufactured using press processing in which a plate, which is a raw material for the cover portion 111, is pressed into a mold.

However, the present invention is not limited to this, and the protrusion 113 may be manufactured using various manufacturing methods, and the protrusion 113 may be formed as a separate component from the cover portion 111.
