  As shown in FIG. 10 and the like, in this embodiment, as an example, the wall 7a is positioned along the inside of the housing 2 of the wall 2n1 (2n) of the member 2Fr. Further, the wall portion 7b is connected to the rear end portion 7c of the wall portion 7a, and as shown in FIG. 4, the surface 6b of the display device 6 (rear surface, back surface, back surface, surface opposite to the surface 6a). Located along. The support members 7A to 7C can be formed by bending a plate-like member. In that case, the end portion 7c is a bent portion of the wall portion 7a and the wall portion 7b. The wall 7a is fixed to the member 2Fr. Therefore, as shown in FIG. 12, the display device 6 is sandwiched between the wall 2k of the member 2Fr and the wall 7b of the support members 7A to 7C fixed to the member 2Fr. That is, the peripheral edge of the display device 6 is surrounded from the outside by the wall 2k, the wall 2n of the member 2Fr, the wall 7a of the support members 7A to 7C, and the wall 7b of the support members 7A to 7C. Although the structures of the wall portions 7b of the support members 7A to 7C are different from each other, the functions of the wall portions 7a and 7b of the support members 7A to 7C relating to the sandwiching of the display device 6 and the peripheral portion of the display device 6 are the same. It is.

  Moreover, as FIG. 7-10 etc. show, in this embodiment, the slit 7d (notch, opening, opening part) is provided in support member 7A-7C as an example. The support members 7 </ b> A to 7 </ b> C are fixed to the support portion 8 by inserting a part of the support portion 8 provided in the housing 2 into the slit 7 d (in this embodiment, as an example, the wall portion 8 b). . Specifically, in the present embodiment, the slit 7d is a central portion in the height direction of the wall portion 7a (the thickness direction of the housing 2 and the display device 6), and the width direction (the surface 6c (side surface) of the display device 6). This is configured as a notch extending from one edge in the longitudinal direction) to the center in the width direction along the width direction.

  As shown in FIGS. 10 and 11, in this embodiment, as an example, the member 2Fr is provided with a support portion 8 that supports the support members 7A to 7C. The support part 8 has the protrusion part 8a. As shown in FIG. 12, the protrusion 8a has a wall 8b and a wall 8c. The wall 8b is directed from the end 2s of the member 2Fr on the member 2Rr side (rear side, rear surface side, back side, back side, back side, back side) to the surface 6c side (inside the housing 2) of the display device 6. Protruding. The wall 8b extends along the peripheral edge of the display device 6 (along the longitudinal direction of the wall 2n). The wall portion 8c protrudes from the wall portion 8b toward the opposite side (the surface 6b side) of the surface 6a along the wall portion 2n2 at a position spaced apart from the wall portion 2n2 of the member 2Rr. Yes. The wall 8c also extends along the peripheral edge of the display device 6 (along the longitudinal direction of the wall 2n). That is, as a whole, the protruding portion 8a protrudes in an L shape from the wall 2n1 of the member 2Fr to the inside of the housing 2. The wall 8c is an example of a portion extending toward the opposite side of the surface 6a on the surface 6c side of the wall 2n2.

  Moreover, as FIG. 10-12 shows, in this embodiment, the support part 8 has the protrusion part 8d in the position spaced apart from the protrusion part 8a to the surface 6a side as an example. In the present embodiment, as an example, the protruding portion 8d is formed on the surface 2t (rear surface, back surface, back surface) of the wall portion 2k, on the opposite side of the surface 6a (rear side, rear surface side, back side, back side, back side, back side, back surface side. ). Further, the protrusion 8d extends along the wall 2n1 of the member 2Fr. The protrusion 8d can be provided on the wall 2n1. In this case, the protruding portion 8d can be formed in an L shape (hook shape) protruding away from the wall 2n1 and protruding toward the opposite side of the surface 6a, for example, like the protruding portion 8a. However, when the projection 2d is provided on the surface 2t of the wall 2k, the projecting portion 8d can be obtained with a simpler configuration, and the external force acting on the inner side of the housing 2 acting on the wall 2n1 is supported by the support members 7A to 7C and Since it can be transmitted to the wall portion 2k via the protruding portion 8d, the rigidity tends to be higher.

  10-12, in this embodiment, support member 7A-7C is fixed to protrusion part 8a, 8d of the support part 8 as an example. Specifically, for example, as shown in FIG. 10, the operator inserts the wall portion 8b into the slit 7d of the support members 7A to 7C, and separates the end portion (from the slit 7d of the support members 7A to 7C ( The supporting members 7A to 7C are supported by inserting the leading end portion of the wall portion 7a, the end portion on the opposite side of the end portion 7c of the wall portion 7a) 7g between the protruding portion 8d and the wall portion 2n1 of the member 2Fr. Engage with 8. Thereby, support member 7A-7C is fixed to each support part 8. As shown in FIG. In such a configuration, before the member 2Rr is attached (that is, in a state where the support members 7A to 7C are temporarily held by the support portion 8 of the member 2Fr), the support members 7A to 7C are inclined to the outside of the housing 2 When the external force acts, the supporting members 7A to 7C are mainly supported by the wall 2n1 and the protruding portion 8d of the member 2Fr. In addition, when an external force in a direction of falling to the inside of the housing 2 is applied to the support members 7A to 7C before the member 2Rr is attached, the support members 7A to 7C are mainly formed of the wall 2n1 of the member 2Fr and the protruding portion 8a. Supported by the wall 8c. Further, after the member 2Rr is attached, as shown in FIG. 12, the wall portion 7a of the support members 7A to 7C is sandwiched between the wall portion 2n2 of the member 2Rr and the wall portion 8c of the protruding portion 8a. . Therefore, when an external force toward the inside of the housing 2 acts on the wall 2n2 of the member 2Rr, the external force can be received by the wall 2n2, the wall 7a, and the wall 8c. That is, according to the configuration according to the present embodiment, the rigidity or strength with respect to the external force acting on the wall 2n2 of the member 2Rr toward the inside of the housing 2 is easily increased by the amount of the wall 8c. Note that the attachment of the support members 7A to 7C to the support portion 8 is performed after the member 2Fr and the display device 6 are arranged in a positional relationship in the assembly state.

  In the present embodiment, as an example, the support members 7B and 7C attached to the wall 2n1 extending along the vertical direction are slid from the upper side to the lower side and attached (inserted) to the support unit 8. With such a configuration, the support members 7B and 7C are in a state of being caught by the support portion 8 from above when the member 2Fr is erected in the same posture as the assembled state. Therefore, according to the present embodiment, as an example, when the support members 7B and 7C are attached to the member 2Fr, for example, during assembly work, the support members 7B and 7C come out of the support portion 8 due to gravity, vibration, or the like. Can be suppressed.

  In the present embodiment, as an example, the plurality of support members 7A attached to the wall 2n1 extending in the left-right direction are all slid from the right side to the left side in the rear view and attached to the support unit 8 (inserted). ) If the mounting directions are different, the shape of the parts of the support member 7A will be different. In this regard, according to the present embodiment, as an example, the manufacturing cost of the support member 7A can be reduced. Moreover, according to the present embodiment, as an example, it is easy to reduce work mistakes or increase work efficiency. Note that all of the plurality of support members 7A may be attached to the support portion 8 by sliding from the left side to the right side in a rear view.

  As shown in FIGS. 10 and 11, in the present embodiment, as an example, the support portion 8 has a protruding portion 8 e extending between the protruding portion 8 a and the protruding portion 8 d. The protruding portion 8e protrudes from the wall portion 2n1 of the member 2Fr toward the inside of the housing 2 (side of the surface 6c). Further, the protruding portion 8e extends along a direction crossing in the longitudinal direction of the protruding portion 8a and the protruding portion 8d (in this embodiment, as an example, a direction crossing the surface 6a, a front-rear direction). With such a configuration, as an example, the rigidity of the support portion 8 is further increased. Moreover, in this embodiment, the protrusion part 8e is provided in the front side of the direction (insertion direction) to which the support members 7A-7C are slid to the support part 8 as an example. Therefore, as an example, the protruding portion 8e can be used as a stopper (abutting portion) when the support members 7A to 7C are attached. The protrusion 8e is an example of a span.

  As shown in FIG. 10, in the present embodiment, as an example, the member 2Rr may be provided with a protruding portion 2u that protrudes toward the member 2Fr. This protrusion 2u is located close to the front side (rear side) of the sliding direction (insertion direction) with respect to the support members 7A to 7C. With such a configuration, as an example, the protrusions 2 u can suppress the support members 7 </ b> A to 7 </ b> C from coming off (separating) from the support part 8. The protruding portion 2u is an example of a second engaging portion.

  As shown in FIGS. 8 and 9, in the present embodiment, the support members 7 </ b> B and 7 </ b> C are provided with a fixing portion 7 e for fixing the coupler 13. The fixing portion 7e is, for example, a female screw portion (female screw hole). A fixing tool 13 is fixed to the fixing portion 7e through which an opening (for example, a through hole, a notch, etc., not shown) provided in the wall 2m of the member 2Rr is passed from the surface 2b side. That is, the support members 7B and 7C also function as brackets for fixing the member 2Rr to the display device 6. With this configuration, as an example, it is not necessary to provide the fixing unit for the coupler 13 in the display device 6, so that the labor for manufacturing the display device 6 can be reduced. For example, the versatility of the display device 6 is likely to increase.

  However, in the present embodiment, as an example, the coupling tool 13 is not fixed to the support members 7B and 7C located on the uppermost side among the three support members 7B and 7C. That is, in the present embodiment, as an example, the support members 7B and 7C coupled to the member 2Rr by the coupler 13 on the surface 6b side of the display device 6 (in the present embodiment, as an example, the second from the top in FIG. On the side closer to the corners 2g, 2h of the housing 2 than the third support member 7B, 7C), the support members 7B, 7C that are not coupled to the member 2Rr by the coupler 13 (in this embodiment, as an example, FIG. The uppermost support members 7B and 7C) are provided. In the corner portions 2g and 2h of the housing 2, the member 2Fr is easily separated from the display device 6. In addition, the longer the distance from the fixing position (that is, the position of the support portion 8) to the display device 6 via the coupler 13 of the support members 7B and 7C to the corner portions 2g and 2h, the easier the separation. On the other hand, the member 2Rr has higher rigidity than the member 2Fr because of the wall portion 2m, and is not easily separated from the display device 6 as much as the member 2Fr. Therefore, according to such a configuration, as an example, the configuration in which the member 2Fr and the member 2Rr are easily fixed to the display device 6 via the support members 7B and 7C while ensuring the required rigidity is reduced in the number of parts. It can be obtained as a configuration. Further, in the present embodiment, as an example, support members 7B and 7C provided with a fixing portion 7e at a place where the coupler 13 is not fixed (in the present embodiment, as an example, the uppermost support member 7B in FIG. 4). , 7C). Thereby, as an example, the sharing of parts is promoted to easily reduce the manufacturing cost, and as an example, the manufacturing effort is easily reduced.

  In the present embodiment, as an example, as shown in FIGS. 12 and 13, the wall 2k (first wall) includes a first portion 2k1, a second portion 2k2, and a third portion 2k3. . Specifically, each of the first portion 2k1, the second portion 2k2, and the third portion 2k3 is a part of the wall portion 2k, and is a band-like (plate-like) region extending along the opening 2r. . These three portions (regions) are divided by the position (closeness or distance to the opening 2r or the wall 2n1 (second wall)) and the cross-sectional shape. The first portion 2k1 is located closest to the opening 2r among the three portions (regions). The second part 2k2 is located on the side farther from the opening 2r than the first part 2k1, and is located on the opposite side of the opening 2r of the first part 2k1. The third portion 2k3 is located on the side farther from the opening 2r than the second portion 2k2, and is located on the opposite side of the opening 2r of the second portion 2k2. The third portion 2k3 is located farthest from the opening 2r. The wall 2n1 (second wall) is connected to the peripheral edge of the wall 2k and extends in a direction crossing the wall 2k.

  In the present embodiment, as an example, the first portion 2k1 has a constant thickness th1 from the opening 2r side (the right side in FIG. 13) to the opposite side (the left side in FIG. 13) of the opening 2r. Yes. The third portion 2k3 has a constant thickness th3 from the opening 2r side to the opposite side of the opening 2r. The second portion 2k2 is thinner (gradually reduced) from the thickness th1 of the first portion 2k1 to the thickness th3 of the third portion 2k3 as it is away from the opening 2r. Further, there is a relationship of th1> th2 ≧ th3 between the thickness th2, the thickness th1, and the thickness th3 of the portion of the wall 2n1 that covers the surface 6c of the display device 6. That is, the thickness th2 is thinner than the thickness th1, and the thickness th3 is equal to or less than the thickness th2 (same as or thinner than the thickness th2). Further, the thickness th3 is thinner than the thickness th1. The surface 2a (third surface) is formed in a continuous planar shape from the first portion 2k1 to the third portion 2k3 via the second portion 2k2. On the other hand, as the thickness (th1, th2, th3, etc.) of the wall 2k along the direction crossing (orthogonal) with the edge of the opening 2r (the left-right direction in FIG. 13) changes, Concavities and convexities are formed. That is, the surface 2t is a plane 2t1 (parallel surface, parallel surface, portion) corresponding to the first portion 2k1, an inclined surface 2t2 (portion) corresponding to the second portion 2k2, and a plane 2t3 (parallel) corresponding to the third portion 2k3. Plane, parallel plane, and part). The second portion 2k2 and the third portion 2k3 form a recess on the back side (rear side) of the wall portion 2k.

  As shown in FIG. 12, in the present embodiment, as an example, the display device 6 is a surface 6a (first surface) that is exposed from the opening 2r and whose peripheral edge is covered with the wall 2k and an image is displayed. And a surface 6c (second surface) extending in a direction intersecting with the surface 6a at the peripheral portion of the surface 6a and covered with the wall 2n1.

  According to the inventors' research, it has been found that the member 2Fr may be warped (for example, warping (deformation, bending, etc.) in the direction along the end portions 2c to 2f). Further, it has been found that when the member 2Fr is a so-called resin molded product made by injection molding of a synthetic resin material, the warp may occur. And by the inventors' diligent research for taking the countermeasure, it has been found that the above-mentioned warpage is caused by the difference in thickness between the wall 2k and the wall 2n1, and further, As a countermeasure, on the portion of the wall 2k that is closer to the wall 2n1 side, the second portion 2k2 (that is, the thickness th1 of the first portion 2k1 to the thickness th3 of the third portion 2k3 as the distance from the opening 2r increases) is increased. It has been found that the warp is easily suppressed by providing a portion that is thin (gradually reduced). As an example, this warpage is one of the stress distribution inside the member 2Fr, the state of curing at the time of resin molding (the difference in the curing rate depending on the location, the flow state of the resin material during cooling, etc.), etc. This is thought to be because of the cause. Moreover, in the structure provided with the part where thickness decreases gradually like the 2nd part 2k2, it replaces with the said 2nd part 2k2 as an example, and the structure provided with the part (step part) where thickness changes suddenly. In comparison, an effect that resin molding defects such as so-called sink marks are suppressed is also obtained.

  Furthermore, as a result of diligent research by the inventors, the warp (deformation) described above also occurs when the third portion 2k3 is provided between the second portion 2k2 and the wall portion 2n1 of the wall portion 2k as in the present embodiment. , Bending) is easily suppressed. Further, as a result of intensive studies by the inventors, it is found that the warp (deformation and bending) described above is easily suppressed if the thickness th3 is the same as or thinner than the thickness th2, as in the present embodiment. It was.

  Further, in the present embodiment, as an example, the wall portion 2k (first plate-like portion) of the end portions 2c, 2d, 2f (upper side portion and left and right side portions in FIG. 1) shown in FIG. 12 and 13, the second portion 2 k 2 is not provided for the wall portion 2 k (second plate-like portion) of the end portion 2 e (the lower side portion of FIG. 1). The width of the wall 2k corresponding to the ends 2c, 2d, 2f in the front view of FIG. 1 is narrower than the width of the wall 2k corresponding to the end 2e in the front view of FIG. The inventors' diligent research has revealed that warping in a wide portion is more easily suppressed than in a narrow portion. Therefore, according to the present embodiment, as an example, the configuration of the member 2Fr is further simplified by not providing the second portion 2k2 for the wall portion 2k (second plate-like portion) of the end portion 2e. The Therefore, as an example, the labor and cost of manufacturing are likely to be reduced.

  In the present embodiment, as an example, as shown in FIGS. 12 and 13, the end 7g (first end) on the wall 2k side of the wall 7a (fourth wall) of the support member 7A is: It faces the end 2v (second end, corner 2w) of the wall 2k on the wall 2n1 side. Referring to FIG. 12, if there is no second portion 2k2 and the wall portion 2k is constant at the thickness th1, it follows the wall portion 2n1 of the wall portion 7a in the cross section (YZ cross section) of FIG. It can be seen that the height becomes shorter. According to the present embodiment, as an example, the wall 2k has the second portion 2k2 (and the third portion 2k3), so that the height along the wall 2n1 of the wall 7a in the cross section of FIG. Therefore, as an example, the rigidity of the support member 7A is more likely to increase accordingly.

  In the present embodiment, as an example, as shown in FIG. 13, the gate mark 9 formed by resin molding of the member 2Fr is on the opposite side (surface 2t, plane 2t1) of the surface 2a of the first portion 2k1. Is located. The gate mark 9 is a mark that is formed on a portion separated from the member 2Fr at a portion corresponding to the gate 15 into which a synthetic resin material having fluidity in a molding apparatus (not shown) is injected into the mold. It is. Usually, the gate mark 9 is rough as compared with other portions on the surface of the molded product, and can be identified as a region having irregularities in a circular range or the like. If the gate mark 9 is provided on the second portion 2k2, the second portion 2k2 is a portion where the thickness of the member 2Fr is changed, and therefore in the direction in which the thickness changes (that is, on the left and right in FIG. 13). ) The change in the flow velocity tends to be large, and the trace of the flow of the synthetic resin material having fluidity flowing into the mold (not shown) from the gate 15 is likely to appear on the surface 2a side, for example. In this respect, according to the present embodiment, the gate mark 9 (that is, the gate 15 at the time of resin molding) is located on the opposite side (surface 2t, plane 2t1) from the surface 2a of the first portion 2k1, so that It is hard to reveal traces.

  As described above, in the present embodiment, as an example, in the member 2Fr, the portion extending toward the wall 2n1 side of the wall 2k extends along the opening 2r from the thickness th1 as the distance from the opening 2r increases. A second portion 2k2 is provided in which the thickness is decreased (gradually decreased) until the thickness th3 is smaller than the thickness th2. As an example, a third portion 2k3 having a thickness th3 extending along the opening 2r is provided between the second portion 2k2 and the wall 2n1. Therefore, according to the present embodiment, as an example, warping of the member 2Fr (for example, warping (deformation, bending) in a direction along the end portions 2c to 2f) is easily suppressed.

  As mentioned above, although embodiment of this invention was illustrated, the said embodiment is an example to the last, Comprising: It is not intending limiting the range of invention. These embodiments can be implemented in various other forms, and various omissions, replacements, combinations, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.

  For example, unlike the member 2Fr1 according to the modification shown in FIG. 14, the second portion 2k2 may extend to the wall 2n1 side without the third portion 2k3. The member 2Fr1 can be used in place of the member 2Fr, and in this case, the same effect as in the above embodiment can be obtained. Further, the technical features of the above-described embodiments and modifications can be implemented by appropriately combining or partially replacing them. In addition, the specifications of each component (structure, type, direction, shape, size, length, width, thickness, height, number, arrangement, position, material, etc.) should be changed as appropriate.
