[0009] [Embodiment 1] A first embodiment of the present invention will be described below with reference to the drawings. The following describes an example in which the housing structure according to the present invention is applied to a housing 12 of a display device 1 for a television receiver. However, the present invention is not limited to this, and can also be applied to housings of display devices for computers, etc. It can also be applied to housings of other devices, such as various recorders such as DVD recorders and Blu-ray disc recorders, and sound bars.

[0010] In addition, in order to make the explanation clearer, the drawings may schematically show the width, thickness, shape, etc. of each part compared to the embodiment, and the width, thickness, shape, etc. of each part in the drawings do not limit the present invention.

[0011] <Outline of Display Device 1> 1 is a diagram showing an example of the appearance of a display device 1 according to a first embodiment of the present invention. The diagram indicated by reference numeral 100A is a perspective view of the display device 1, the diagram indicated by reference numeral 100B is a front view, and the diagram indicated by reference numeral 100C is a rear view.

[0012] Here, when viewing the display panel 11 from the front, the direction pointing left in the width direction of the display panel 11 is referred to as the X1 direction, and the direction opposite to the X1 direction is referred to as the X2 direction. The direction pointing upward in the height direction of the display panel 11 is referred to as the Y1 direction, and the direction opposite to the Y1 direction is referred to as the Y2 direction. Furthermore, the direction perpendicular to X1 and X2 and also perpendicular to Y1 and Y2, running from the back side to the front side of the display panel 11 is referred to as the Z1 direction, and the direction opposite to the Z1 direction is referred to as the Z2 direction. Note that when X1 and X2, Y1 and Y2, and Z1 and Z2 are referred to collectively without distinction, they will be referred to as the X direction, Y direction, and Z direction, respectively.

[0013] As shown in FIG. 1, the display device 1 includes a display panel 11, a housing 12 including a rear cover (cover member) 2, and the like, and a chassis part 5 (see FIG. 3) located inside the housing 12.

[0014] The display panel 11 is configured, for example, in a horizontally long rectangular shape, and displays images and various information, etc. The display panel 11 is realized by a liquid crystal display, an organic EL display, a plasma display, or the like.

[0015] The chassis 5 is made of metal and is located on the rear side of the display panel 11, and is formed, for example, in a horizontally long rectangular shape similar to the display panel 11. The display panel 11, rear cover 2, and other electronic components are attached to the chassis 5. The chassis 5 also has an LED board (not shown) attached thereto and is equipped with a heat dissipation function for the LED board.

[0016] The housing 12 includes a rear cover 2, an upper rear cover 2a, various panels (not shown) such as a front panel, and an opening 121 (see 300A in FIG. 3).

[0017] The opening 121 is located on the rear side of the chassis 5 and is an opening on the rear side of the display device 1. When the display device 1 is in use, the opening 121 is covered by the rear cover 2 and the upper rear cover 2a.

[0018] The rear cover 2 is located on the rear side of the opening 121, is disposed on the rear side of the display device 1 so as to cover the opening 121, and is detachably attached to the display panel 11 via the chassis part 5. The rear cover 2 is removed from the display panel 11, for example, when the display device 1 is inspected, repaired, or disassembled.

[0019] As will be described in detail later, the rear cover 2 is fixed to the display panel 11 by engagement between a first engagement portion 3 of the rear cover 2 and a second engagement portion 4 of the chassis portion 5. Furthermore, by rotating a second edge 27, which is an edge on the lower side (Y2 direction) of the rear cover 2, around a first edge 26, which is an edge on the upper side (Y1 direction) of the rear cover 2, as a rotation axis so as to move away from the opening 121, the engagement between the first engagement portion 3 and the second engagement portion 4 is released, and the rear cover 2 can be removed from the display panel 11. Furthermore, by removing the rear cover 2, the opening 121 is opened.

[0020] At the boundary between the rear cover 2 and the upper rear cover 2a, a locking portion 26a is provided that locks the rear cover 2 to the upper rear cover 2a while the rear cover 2 is rotating (see reference numeral 800C in FIG. 8). The locking portion 26a is composed of a locking piece 7 formed at the lower end of the upper rear cover 2a and a locking piece 6 formed near the first edge 26 of the rear cover 2. When the rear cover 2 begins to rotate, the rear cover 2 is locked to the upper rear cover 2a by the locking portion 26a, but when the rear cover 2 is released from the display panel 11, the locking state of the locking portion 26a is released. In this way, the locking portion 26a allows the rear cover 2 to rotate around the first edge 26 as a rotation axis.

[0021] In this embodiment, the rear cover 2 rotates in the vertical direction, but may be rotated in the horizontal direction to open and close. In this case, for example, the end edge of the rear cover 2 in the X1 direction (the left side as viewed from the display panel 11 side) is used as a rotation axis to rotate the end edge of the rear cover 2 in the X2 direction (the right side as viewed from the display panel 11 side).

[0022] (Arrangement of first engagement portion 3) 2 is a diagram showing an example of the rear cover 2 in a state where it is removed from the display panel 11. The diagram indicated by reference numeral 200A is a diagram of the rear cover 2 as seen from the inside of the housing 12, and the diagram indicated by reference numeral 200B is an enlarged view of part A in the diagram indicated by reference numeral 200A.

[0023] 2, the rear cover 2 has first engagement portions 3 on the inner wall 25 below (in the Y2 direction) both end portions 24a, 24b in the width direction (in the X direction) of the rear cover 2. The first engagement portions 3 include a first engagement portion 3a disposed on the left side when viewed from the display panel 11 side in a state in which the rear cover 2 is attached to the display panel 11, and a first engagement portion 3b disposed on the right side. When the first engagement portions 3a and 3b are referred to collectively without being distinguished from each other, they are referred to as the first engagement portions 3.

[0024] The first engagement portion 3 engages with a second engagement portion 4 provided on a chassis portion 5 inside an opening 121, which will be described later, thereby fixing the rear cover 2 to the display panel 11. With the rear cover 2 attached to the display panel 11, the first engagement portion 3a is positioned to engage with the second engagement portion 4a, and the first engagement portion 3b is positioned to engage with the second engagement portion 4b. Details of the engagement between the first engagement portion 3 and the second engagement portion 4 will be described later.

[0025] The number of first engagement portions 3 is not particularly limited as long as it is at least two. The positions of the first engagement portions 3 are not limited to the above positions, and are not particularly limited as long as they are positions that can engage with the second engagement portions 4 and that allow the rear cover 2 to elastically deform when the rear cover 2 is removed. The elastic deformation of the rear cover 2 will be described later.

[0026] (Arrangement of second engagement portion 4) 3 is a diagram showing an example of the interior of the display device 1 with the rear cover 2 and the upper rear cover 2a removed. The diagram indicated by reference numeral 300A is a diagram showing the interior of the display device 1 as seen from the rear side of the display device 1, and the diagram indicated by reference numeral 300B is an enlarged view of part B of the diagram indicated by reference numeral 300A.

[0027] As described above, the rear cover 2 is arranged to cover the opening 121 of the housing 12, and by removing the rear cover 2, the inside of the display device 1 can be exposed from the opening 121 of the housing 12, as shown in Fig. 3. At this time, the chassis part 5 located inside the housing 12 is also exposed.

[0028] The chassis 5 is provided with second engagement portions 4 below (in the Y2 direction) both end portions 12a, 12b of the housing 12 in the X direction. The second engagement portions 4 include a second engagement portion 4a disposed on the left side when viewed from the display panel 11 side, and a second engagement portion 4b disposed on the right side. Note that the second engagement portions 4a and 4b will be referred to collectively as the second engagement portion 4 when they are not distinguished from each other.

[0029] As described above, the second engagement portion 4a is disposed at a position where it engages with the first engagement portion 3a, and the second engagement portion 4b is disposed at a position where it engages with the first engagement portion 3b when the rear cover 2 is attached to the display panel 11. Details of the second engagement portion 4 will be described later.

[0030] The number of second engagement portions 4 may be the same as the number of first engagement portions 3. In addition, the locations of the second engagement portions 4 are not limited to the above positions, and are not particularly limited as long as they are positions that can engage with the first engagement portions 3.

[0031] <First engagement portion 3> Fig. 4 is a perspective view showing an example of the appearance of the first engagement portion 3. The view indicated by reference numeral 400A is a perspective view of the first engagement portion 3a provided on the inner wall 25 of the rear cover 2, as seen from above (the Y2 direction side), and the view indicated by reference numeral 300B is a perspective view of the first engagement portion 3a, as seen from below (the Y1 direction side). Note that Fig. 4 describes the first engagement portion 3a, and as the first engagement portion 3b is configured symmetrically to the first engagement portion 3a, its description will not be repeated unless necessary.

[0032] As shown in FIG. 4, the first engagement portion 3a is provided on the inner wall 25 of the rear cover 2, and includes an engagement piece 31 and a leg portion 32.

[0033] The engagement piece 31 is a portion that engages with the second engagement portion 4, and is formed in a hook shape. Although details will be described later, the engagement piece 31 is formed so as to extend from the central portion 24c side (see FIG. 9) of the rear cover 2 toward the end portion 24a side of the rear cover 2 in a cross section parallel to the first end side 26 of the rear cover 2. The engagement piece 31 of the first engagement portion 3b is formed so as to extend from the central portion 24c side toward the end portion 24b side opposite the first engagement portion 3a.

[0034] The engagement piece 31 includes an engagement surface 311 and an inclined portion 312. The engagement surface 311 is a surface that engages with an engagement surface 431 of the second engagement portion 4, which will be described later.

[0035] The inclined portion 312 is formed on the lower portion (Y2 direction side) of the engagement piece 31, and is formed so that the engagement surface 311, which is the portion that engages with the second engagement portion 4, gradually narrows downward. The inclined portion 312 will be described in detail later.

[0036] The leg 32 has a generally flat plate shape and is provided so as to protrude from the inner wall 25 of the rear cover 2 toward the display panel 11. The base end of the leg 32 is continuous with the inner wall 25 of the rear cover 2, and an engagement piece 31 is provided at the tip end opposite the base end.

[0037] The leg portion 32 is provided with a first rib (rib) 321 on a side 32a where the engagement piece 31 is arranged, and a second rib 322 on a side 32b opposite to the first rib 321. The first rib 321 and the second rib 322 will be described in detail later.

[0038] The first engagement part 3 is made of the same material as the rear cover 2, for example, a resin such as PC-ABS (polycarbonate ABS) or HIPS (high impact polystyrene). The first engagement part 3 may be integrally formed with the rear cover 2, or may be manufactured separately from the rear cover 2 and then fixed to the rear cover 2 with an adhesive or the like.

[0039] <Second engagement portion 4> The second engagement portion 4 is a member that engages with the first engagement portion 3, and is provided inside the opening 121 of the housing 12. The second engagement portion 4 is attached to, for example, the chassis portion 5 that is located inside the opening 121 of the housing 12. However, the second engagement portion 4 is not limited to this, and may be attached to a member other than the chassis portion 5 as long as it is inside the opening 121 of the housing 12.

[0040] Fig. 5 is a perspective view showing an example of the appearance of the second engagement portion 4. As shown in Fig. 5, the second engagement portion 4 is made of metal such as aluminum or iron, and is formed in a generally rectangular plate shape. The second engagement portion 4 includes, for example, a flat portion 41 which is a generally flat portion, a rising portion 42, an elongated hole portion (hole portion) 43, and a screw hole 44. The flat portion 41 includes a front surface portion 411 and a back surface portion 412.

[0041] The second engagement portion 4 is attached to the chassis portion 5 so that the back surface 412 of the flat portion 41 abuts against the chassis portion 5 and the rising portion 42 is disposed on the end portion 12a or end portion 12b side of the housing 12. The screw holes 44 are used to insert screws that attach the second engagement portion 4 to the chassis portion 5.

[0042] The rising portion 42 is formed by bending one end of the second engagement portion 4 toward the rear side of the display device 1.

[0043] The elongated hole 43 is a through-hole formed across part of the rising portion 42 and part of the flat portion 41, and is formed to extend in the Y direction. The elongated hole 43 has an engagement surface 431 on its periphery, and the engagement surface 431 engages with the engagement surface 311 of the first engagement portion 3. The engagement piece 31 of the first engagement portion 3 is inserted into the elongated hole 43 so that the engagement surface 311 of the engagement piece 31 engages with the engagement surface 431 of the elongated hole 43.

[0044] <Engagement between the first engagement portion 3 and the second engagement portion 4> Fig. 6 is a schematic diagram showing an example of an engagement state between the first engagement portion 3 and the second engagement portion 4, as viewed from the side of the display device 1. Fig. 7 is a schematic diagram illustrating the engagement between the first engagement portion 3 and the second engagement portion 4 when the rear cover 2 is attached.

[0045] As shown in Figure 6, the engagement surface 311 of the first engagement portion 3 is positioned within the long hole portion 43, and the engagement surface 311 of the first engagement portion 3 and the engagement surface 431 of the long hole portion 43 of the second engagement portion 4 abut against each other and engage with each other, thereby engaging the first engagement portion 3 and the second engagement portion 4.

[0046] As shown in FIG. 7 , when attaching the rear cover 2 to the display panel 11 via the chassis 5, the engagement pieces 31 of the first engagement portions 3 are inserted into the elongated hole portions 43 of the second engagement portions 4. Because the portions with which the first engagement portions 3 engage are hole-shaped, i.e., the upper and lower ends of the engaging portions are continuous with the flat portions 41, the strength of the second engagement portions 4 is maintained, which reduces deformation, bending, etc. of the second engagement portions 4 due to the first engagement portions 3, making it difficult for the first engagement portions 3 to come off the elongated hole portions 43. Furthermore, even if the first engagement portions 3 move in the up-down direction (Y direction) of the housing 12, the first engagement portions 3 come into contact with the end faces of the elongated hole portions 43, making it difficult for the first engagement portions 3 to come off, and making it easier to maintain the engaged state.

[0047] In this way, the display device 1 of this embodiment can fix the rear cover 2 to the display panel 11 via the chassis part 5 without using fastening members such as screws, and the rear cover 2 can be attached to the display panel 11.

[0048] Furthermore, as will be described in more detail later, the engagement between the first engagement portion 3 and the second engagement portion 4 can be released simply by sliding the engagement piece 31 of the first engagement portion 3 in the direction of removal from the long hole portion 43 (X direction).

[0049] <Removing and disengaging the rear cover 2> Fig. 8 is a schematic diagram illustrating an example of rotational movement of the rear cover 2. The view indicated by reference numeral 800A in Fig. 8 is a perspective view of the display device 1 as seen from the rear side, and the view indicated by reference numeral 800B is a perspective view as seen from the side. The view indicated by reference numeral 800C is a diagram showing the locking portion 26a that locks the rear cover 2 to the upper rear cover 2a.

[0050] 8, the rear cover 2 can be removed by rotating the second end edge 27 of the rear cover 2 around the first end edge 26 of the rear cover 2 as a rotation axis so as to move the second end edge 27 of the rear cover 2 away from the opening 121. For example, at least the central portion 24d of the rear cover 2 extends to the bottom side of the display device 1, and an operator places their hand on the bottom side of the central portion 24d of the rear cover 2 and rotates and lifts the rear cover 2 toward the back side of the display device 1. At this time, as the central portion 24d of the rear cover 2 is lifted, the central portion 24c of the rear cover 2 is bent and elastically deformed.

[0051] Furthermore, a notch is formed in the central portion 24c of the rear cover 2, and the length from the first edge 26 to the top of the notch is shorter than the length from the first edge 26 to the second edge 27. Therefore, the force when lifting the rear cover 2 is easily transmitted to the central portion 24c without being dispersed, making it easy to bend the central portion 24c. Note that the rear cover 2 does not have to extend to the bottom side of the display device 1, and the central portion 24c of the rear cover 2 does not have to have a notch formed therein.

[0052] FIG. 9 is a schematic diagram illustrating an example of movement of the first engagement portion 3 when the rear cover 2 is removed. The view indicated by reference numeral 900A in FIG. 9 is a cross-sectional view taken along line IX-IX (see FIG. 8) showing the state before the rear cover 2 is removed. The view indicated by reference numeral 900B is a cross-sectional view taken along line IX-IX showing the state after the rear cover 2 is removed. Note that line IX-IX is an imaginary plane parallel to the first end side 26 of the rear cover 2. FIG. 10 is a schematic diagram illustrating an example of movement of the first engagement portion 3.

[0053] As shown by the symbol 900A, when the rear cover 2 is attached to the display panel 11, the engagement surface 311 of the first engagement portion 3 and the engagement surface 431 of the second engagement portion 4 abut against each other and are engaged with each other.

[0054] Here, as described above, the engagement piece 31 is formed so as to extend from the central portion 24c side of the rear cover 2 toward the end portion 24a or 24b side of the rear cover 2. Therefore, the direction in which the first engagement portion 3 engages with the second engagement portion 4 is the direction from the central portion 24c side toward the end portion 24a or 24b side.

[0055] As shown in the diagram indicated by the reference numeral 900B and in FIG. 10, when removing the rear cover 2, the central portion 24c of the rear cover 2 is lifted in the Z2 direction, and the rear cover 2 is rotated around the first end side 26 as the rotation axis so as to move away from the opening 121. This causes the central portion 24c to bend in the P1 direction (Z2 direction), and the end portions 24a and 24b to bend in the P2 direction (toward the display panel 11). This causes the end portions 24a and 24b to move in the P3 direction (X direction). Here, the P3 direction is the direction from the end portion 24a or 24b side toward the central portion 24c side.

[0056] As the ends 24a and 24b move in the P3 direction, the first engagement portions 3a and 3b provided on the ends 24a and 24b also move in the P3 direction.

[0057] Meanwhile, as described above, the direction in which the first engagement portion 3 engages with the second engagement portion 4 is the direction from the center portion 24c toward the end portion 24a or 24b. The P3 direction is the opposite direction to the engagement direction, and therefore the P3 direction is the direction in which the engagement is released. Therefore, the first engagement portions 3a and 3b move in the direction in which the engagement is released. As a result, the engagement surface 311 of the first engagement portion 3 moves away from the engagement surface 431 of the second engagement portion 4, and the engagement between the engagement surface 311 and the engagement surface 431 is released.

[0058] As a result, the worker can disengage the first engagement portion 3 from the second engagement portion 4 and remove the rear cover 2 simply by lifting the vicinity of the central portion 24c of the rear cover 2 toward the rear side. In this way, the engagement is also released by the action of removing the rear cover 2, so a separate action for disengaging the engagement is not required and the rear cover 2 can be easily removed.

[0059] <Slope part 312> As described above, the engagement piece 31 of the first engagement portion 3 has the inclined portion 312. The inclined portion 312 is formed to facilitate disengagement between the engagement piece 31 of the first engagement portion 3 and the second engagement portion 4 when removing the rear cover 2. The inclined portion 312 will be described in detail below with reference to the drawings. Note that the inclined portion 312 is not an essential component, and the first engagement portion 3 does not necessarily have to have the inclined portion 312.

[0060] Fig. 11 is a diagram showing an example of the inclined portion 312 of the first engagement portion 3. Fig. 12 is a diagram illustrating the inclined portion 312 of the first engagement portion 3.

[0061] As shown in Figures 11 and 12, the inclined portion 312 is formed on the lower part (Y2 direction side) of the engagement piece 31, and is formed so that the engagement surface 311, which is the part that engages with the second engagement portion 4, gradually narrows toward the second end edge 27 side (lower side).

[0062] Here, the upper side (Y1 direction side) of the engagement piece 31 is the first end edge 26 side which becomes the rotation axis when removing the rear cover 2, and the lower side of the engagement piece 31 is the second end edge 27 side of the rear cover 2. When removing the rear cover 2, the second end edge 27 is rotated around the first end edge 26 as the rotation axis so as to move away from the opening 121.

[0063] Therefore, the direction in which the engagement is released is the Y1 direction in the engagement piece 31. In other words, the engagement piece 31 is released from the second engagement portion 4 from the bottom side toward the top side.

[0064] By forming the inclined portion 312 on the lower side where the engagement begins to disengage, the inclined portion 312 acts as a trigger for disengaging with the second engagement portion 4, making it easier to disengage the engagement piece 31 from the second engagement portion 4.

[0065] 12, even when the rear cover 2 is attached to the display panel 11, that is, when the first engagement portion 3 and the second engagement portion 4 are engaged, the lower end 312a of the inclined portion 312 is configured not to engage with the second engagement portion 4. This makes it easier to disengage the engagement piece 31 from the second engagement portion 4. However, this is not limiting, and the lower end 312a may be engaged with the second engagement portion 4.

[0066] <First rib 321> Fig. 13 is a diagram showing an example of the first rib 321 (rib) of the first engagement portion 3. Fig. 13 is a cross-sectional view of a part of the rear cover 2 taken along line IX-IX.

[0067] As shown in Figures 7, 11, and 13, a first rib 321 is provided on the leg portion 32 of the first engagement portion 3 on the side 32a where the engagement piece 31 is formed, and a second rib 322 is provided on the side 32b opposite the first rib 321.

[0068] The second rib 322 is a rib for reinforcing the first engagement portion 3 and is provided to prevent the first engagement portion 3 from being damaged, for example, during molding of the first engagement portion 3. In this embodiment, two second ribs 322 are provided, but this is not limitative and one, or three or more, may be provided. Also, the second rib 322 may not be provided.

[0069] The first rib 321 is formed to make it difficult for the engagement piece 31 of the first engagement portion 3 to disengage from the second engagement portion 4 when the rear cover 2 is removed. By providing the first rib 321 on the leg portion 32, it is possible to prevent deformation of the first engagement portion 3 and strengthen the engagement force with the second engagement portion 4. This makes it possible to prevent the engagement with the second engagement portion 4 from becoming too easily disengaged.

[0070] In addition, only one first rib 321 is provided at the end 32c on the first end side 26 side (Y1 direction) of the leg portion 32, and no first rib 321 is provided at the end 32d on the second end side 27 side (Y2 direction).

[0071] If the first rib 321 were provided on both the end 32c and the end 32d, the engagement force would be too strong, making it difficult to remove the rear cover 2. For this reason, the first rib 321 is provided only on the end 32c on the second end side 27 side, where the engagement is maintained until the end, because the engagement disengages in the Y1 direction.

[0072] By providing the first rib 321 only on the end 32c on the second edge 27 side, it is possible to make it easier to disengage from the second engagement portion 4, and also to strengthen the engagement force between the rear cover 2 and the display panel 11.

[0073] In this way, by providing the second engagement portion 4 with the inclined portion 312 and the first rib 321, it is possible to adjust and balance the ease of removal of the rear cover 2 and the engagement force.

[0074] (Shape of the first rib 321) 13, the first rib 321 is configured so that the length L1 from the surface of the inner wall 25 of the rear cover 2 is approximately half the length L2 of the leg portion 32 from the surface of the inner wall 25. This configuration prevents deformation of the first engagement portion 3 and makes it possible to appropriately strengthen the engagement force with the second engagement portion 4.

[0075] Furthermore, the first rib 321 is configured so that the formation start point P1 of the first rib 321 and the formation start point P2 of the second rib 322 have the same length L3 from the engaging piece 31. This configuration prevents deformation of the first engaging portion 3 and makes it possible to appropriately strengthen the engaging force with the second engaging portion 4.

[0076] Furthermore, the length L4 by which the first rib 321 protrudes from the surface of the side 32a on which the engagement piece 31 of the leg portion 32 is formed is formed to be longer than the thickness L5 of the leg portion 32, for example, approximately 1.5 times the thickness L5 of the leg portion 32. This increases the strength of the leg portion 32, suppresses deformation of the leg portion 32 due to bending in the X direction, and makes it difficult for the second engagement portion 4 and the first engagement portion 3 to disengage.

[0077] [Embodiment 2] A second embodiment of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the first embodiment, and the description thereof will not be repeated. The second engagement portion 4A of the second embodiment is formed from a part of the chassis portion 5 of the first embodiment.

[0078] 14 is a diagram showing an example of a second engagement portion 4A according to embodiment 2 of the present invention. The diagram indicated by reference numeral 1400A shows the engagement between the second engagement portion 4A and the first engagement portion 3, and the diagram indicated by reference numeral 1400B is a diagram of the second engagement portion 4A as seen from the rear cover 2 side (Z1 direction).

[0079] As shown in FIG. 14, the second engagement portion 4A includes a notch 45, a folded portion 46, and an engagement surface 431A.

[0080] The notch 45 is a portion where the chassis part 5 is cut out, for example, in a U-shape.

[0081] The folded portion 46 is a portion where the cut-out end portion 5a of the chassis portion 5 is folded back toward the rear cover 2 side (Q1 direction) at a folding point 46a.

[0082] The engagement surface 431A is a portion that engages with the engagement surface 311 of the first engagement portion 3, and is a portion that is located in the vicinity of the turning point 46a.

[0083] In this way, the second engagement portion 4A is formed by bending a part of the chassis portion 5, so that the number of parts can be reduced, and manufacturing costs and labor can be reduced.

[0084] 〔summary〕 A housing structure according to a first aspect of the present invention comprises an opening and a cover member that covers the opening, and the opening is opened by rotating the cover member away from the opening around a first end edge of the cover member as a rotation axis, and further comprises a first engagement portion provided on an inner wall of the cover member and a second engagement portion provided within the opening and engaging with the first engagement portion, and the first engagement portion extends from the center side of the cover member to the end side of the cover member in a cross section parallel to the first end edge.

[0085] A housing structure according to aspect 2 of the present invention may be such that, in the above-mentioned aspect 1, the cover member is lifted near the center of the second end side opposite the first end side, causing the cover member to rotate and bend, and the first engagement portion to move from the end side of the cover member to the center side.

[0086] According to the above aspect, when the cover member is rotated, the cover member bends and the first engagement portion moves from the end side to the center side of the cover member, thereby disengaging the engagement. Because the engagement is also released by the action of removing the cover member, a separate action for disengaging the engagement is not required, and the cover member can be easily removed.

[0087] A housing structure according to aspect 3 of the present invention may be such that, in aspect 2 above, the first engagement portion has an inclined portion in which the portion that engages with the second engagement portion gradually narrows toward the second end edge side.

[0088] According to the above configuration, the inclined portion acts as a trigger for disengaging the first engaging portion from the second engaging portion, making it easier to disengage the first engaging portion.

[0089] A housing structure according to aspect 4 of the present invention is any one of aspects 1 to 3 above, wherein the first engagement portion has a leg portion connected to the cover member, and the leg portion has a rib on the first end edge side.
