Description

The present invention relates to a split-type lid device and its assembly method.

Conventionally, split-type lid devices in which the lids open like a double door are known (for example, see Patent Document 1). This split-type lid device comprises a box body with an opening, and two lids that open and close the opening of the box body. In order to smoothly open and close these two lids, it is necessary to configure the lids so that a gap is provided between the opposing portions of the two lids that face each other when both lids are in the closed position.

JP 2020-032977 A

The gap between the opposing parts must be at least the minimum size required to prevent the lids from interfering with each other when opening and closing the lids. However, since there is variation in assembly between the lid and the box body, the gap is generally made larger than the minimum size so that it does not fall below the minimum size even if there is variation in assembly.

However, if the gap is formed with the aim of being larger than the minimum size as described above, the actual gap may be larger than the minimum size due to the above-mentioned assembly variations. If the actual gap is larger than the minimum size, the inside of the box body may be fully visible through the gap, or objects may easily fall into the box body through the gap. To prevent this from happening, it is possible to provide a rubber fin or the like on the side of each lid to close the above-mentioned gap when the lid is in the closed position. However, providing the above-mentioned rubber fin or the like on the side of the lid in this way may deteriorate the appearance when the lid is in the open position, or, if the side of the lid is used as an armrest, the rubber fin or the like on the side of the lid may impede the armrest function.

The present invention was made in consideration of these points, and aims to provide a split-type lid device and an assembly method thereof that can minimize the gap between the opposing portions of the two lids in the closed position, even if there is variation in the assembly between the two lids and the box body.

One aspect of the present invention is a split-type lid device comprising a first box part and a second box part assembled together to form a box body having an opening, a first lid that opens and closes a first region of the opening and is supported by the first box part so as to be capable of opening and closing, a second lid that opens and closes a second region of the opening and is supported by the second box part so as to be capable of opening and closing, and a gap that is formed between opposing portions of the first lid and the second lid when both the first lid and the second lid are in the closed position, and the first box part and the second box part each have a temporary joint portion that is temporarily joined to each other with an adjustment allowance that allows adjustment of the distance between the opposing portions in the contact and separation direction.

According to this configuration, when the first box part and the second box part are temporarily joined to each other at the temporary joint, the distance between the opposing portions of the first lid and the opposing portions of the second lid in the closed position can be adjusted by adjusting the adjustment margin of the temporary joint of each box part. In this regard, by adjusting the distance between the opposing portions of the two lids in the closed position when the two box parts are temporarily joined to each other, the gap between the opposing portions can be minimized as much as possible. Therefore, even if there is assembly variation between the two lids and the box body, the gap between the opposing portions of both lids in the closed position can be minimized as much as possible.

Another aspect of the present invention is a method for assembling the above-mentioned split-type lid device, comprising: a first step of temporarily joining the first box part and the second box part to each other at the temporary joining portion; a second step of placing an auxiliary jig having a thickness equivalent to the gap between the opposing portions and sandwiching the first lid and the second lid in a state in which the first box part and the second box part are temporarily joined to each other at the temporary joining portion; and a third step of permanently joining the first box part and the second box part to each other in a state in which the auxiliary jig is sandwiched between the first lid and the second lid.

According to this configuration, when the first box part and the second box part are temporarily joined to each other at the temporary joint, the distance between the opposing portions of the first lid and the opposing portions of the second lid in the closed position can be adjusted by adjusting the adjustment margin of the temporary joint of each box part. In this regard, by adjusting the distance between the opposing portions of the two lids in the closed position when the two box parts are temporarily joined to each other, the gap between the opposing portions can be minimized as much as possible. Therefore, even if there is assembly variation between the two lids and the box body, the gap between the opposing portions of both lids in the closed position can be minimized as much as possible.

Below, a specific embodiment of the split-type lid device according to the present invention will be described with reference to Figures 1 to 7.

The split-type lid device 1 of this embodiment (hereinafter simply referred to as the lid device 1) is, for example, a console box that is installed in the center console inside the vehicle. The lid device 1 may also be used as an armrest for a vehicle occupant to place their arms on.

In the following, unless there are special circumstances, the contents indicating the direction in the lid device 1 will be based on the vehicle on which the lid device 1 is installed. For example, "right side" refers to the right side of the vehicle in relation to the vehicle's traveling direction, and "left side" refers to the left side of the vehicle in relation to the vehicle's traveling direction.

As shown in Figures 1, 2, and 3, the lid device 1 comprises a box body 10 and a lid 20.

The box body 10 is a box body capable of storing objects. The box body 10 is formed in a substantially rectangular parallelepiped shape. The box body 10 is fixed to the vehicle floor by bolting or the like. The box body 10 has a storage section 11 and an opening 12. The storage section 11 is a portion that forms a space for storing objects. The storage section 11 is formed by a bottom wall and a side wall. The opening 12 is an entrance and exit into the storage section 11. The opening 12 is formed in the upper part of the storage section 11.

As shown in FIG. 3, the box body 10 is composed of two separate parts. The box body 10 is formed of a first box part 10a and a second box part 10b. That is, the first box part 10a and the second box part 10b are assembled together to form the box body 10.

The first box part 10a and the second box part 10b are divided at approximately the center of the box body 10 from left to right. The first box part 10a is located on the left side, and the second box part 10b is located on the right side. The first box part 10a includes the left half of the storage section 11 and the left half of the opening 12. The second box part 10b includes the right half of the storage section 11 and the right half of the opening 12.

The first box part 10a and the second box part 10b each have box facing parts 15 that face each other in the left-right direction. Each box facing part 15 is formed on a surface facing to the right or a surface facing to the left. Each box facing part 15 extends along the frame body (i.e., the bottom wall and the side wall) of the box parts 10a and 10b, and is formed in a roughly U-shape. The first box part 10a and the second box part 10b are assembled together with the box facing parts 15 facing each other to form the box main body 10.

The first box part 10a and the second box part 10b each have an overlapping portion 16 that overlaps with each other. The overlapping portions 16 of both box parts 10a, 10b are arranged so as to overlap in the inside and outside directions of the storage part 11 near the box facing part 15. Each overlapping portion 16 extends in a band shape along the frame body (i.e., the bottom wall and the side wall) of the box parts 10a, 10b, and is formed in a roughly U-shape. The length (i.e., band width) of each overlapping portion 16 in the left-right direction (i.e., overlap width direction) is set so that the overlapping portions 16 always overlap with each other even if manufacturing variations and assembly variations of the box body 10 and the lid 20 are accumulated.

The first box part 10a and the second box part 10b each have a temporary joint 17 that is temporarily joined to each other. Specifically, the first box part 10a has a temporary joint 17a. The second box part 10b has a temporary joint 17b. The temporary joint 17a and the temporary joint 17b are configured as a pair, and multiple pairs (seven pairs in FIG. 3) are provided.

The temporary joints 17a and 17b are used to temporarily join the first box part 10a and the second box part 10b so that they do not separate before they are permanently joined and fixed to each other. This temporary joint allows the first box part 10a and the second box part 10b to move relative to each other in the left-right direction by an adjustment allowance, but does not allow the two box parts 10a and 10b to move relative to each other in the up-down and front-back directions.

The temporary joints 17a, 17b are formed in a shape that allows the first box part 10a and the second box part 10b to slide relative to each other in the left-right direction. The temporary joints 17a, 17b have an adjustment margin that allows the box parts 10a, 10b to move left-right when temporarily joined to each other. As shown in FIG. 4, this adjustment margin is set to a total of approximately (2·X) mm, which allows the first box part 10a and the second box part 10b to move away from each other by X mm (e.g., 1 mm) in the left-right direction from the center position.

For example, as shown in FIG. 4, the temporary joint 17a is disposed near the box facing portion 15 of the first box part 10a and near the overlapping portion 16. The temporary joint 17a is formed so as to protrude from the support portion 18 on the outer surface side of the overlapping portion 16 to the right, which is the second box part 10b side. The temporary joint 17a has a claw portion 17a1 with which the temporary joint 17b of the second box part 10b can engage. The claw portion 17a1 is provided on the protruding tip side of the temporary joint 17a. The claw portion 17a1 is formed so as to protrude outward from the outer surface of the protruding tip of the temporary joint 17a away from the box body 10. The claw portion 17a1 can be elastically deformed inward toward the box body 10. The temporary joint 17a is configured so that the width becomes smaller than the size of the hole portion 17b1 described below due to the elastic deformation of the claw portion 17a1.

The temporary joint 17b is disposed near the box facing portion 15 and near the overlap portion 16 of the second box part 10b. The temporary joint 17b is formed so as to protrude from the outer surface of the overlap portion 16 toward the outside of the box, away from the box body 10. The temporary joint 17b has a hole 17b1 into which the temporary joint 17a of the first box part 10a is inserted. The hole 17b1 is formed so that the temporary joint 17a can penetrate the temporary joint 17b in the left-right direction when the claw portion 17a1 of the temporary joint 17a is elastically deformed.

The temporary joint 17a of the first box part 10a can engage with the temporary joint 17b of the second box part 10b. Specifically, the temporary joint 17a is inserted into the hole 17b1 of the temporary joint 17b with the claw 17a1 elastically deformed, and then the claw 17a1 is released from elastic deformation, allowing it to hook onto the edge of the hole 17b1. In this case, as shown in FIG. 3, the first box part 10a and the second box part 10b can move in the left-right direction by the above-mentioned adjustment allowance, specifically, they can move in the left-right direction toward each other until the temporary joints 17a and 17b abut against each other, and can move in the left-right direction away from each other until the claw 17a1 hooks onto the edge of the hole 17b1.

In addition, instead of the configuration of the temporary joints 17a and 17b shown in Figure 4, for example, the configuration of the temporary joints 107a and 107b shown in Figures 5 and 6 may be used.

For example, the temporary joint 107a is disposed near the box facing portion 15 and near the overlap portion 16 of the first box part 10a. The temporary joint 107a is formed so as to protrude from the overlap portion 16 to the right, which is the side of the second box part 10b. The temporary joint 107a is inserted into a hole 107b3 (described below) of the second box part 10b. The temporary joint 107a has a hole 107a1 with which a claw portion 107b2 (described below) of the second box part 10b can engage. The hole 107a1 is provided on the tip side of the temporary joint 107a so that the claw portion 107b2 can enter inward and outward directions of the box body 10.

The temporary joint 107b is disposed near the box facing portion 15 and near the overlap portion 16 of the second box part 10b. The temporary joint 107b has a frame portion 107b1 and a claw portion 107b2. The frame portion 107b1 is formed so as to protrude from the outer surface of the overlap portion 16 toward the outside of the box away from the box main body 10. The frame portion 107b1 has a hole portion 107b3 into which the temporary joint 107a of the first box part 10a is inserted. The hole portion 107b3 is formed so that the temporary joint 107a can penetrate the frame portion 107b1 in the left-right direction. The claw portion 107b2 is formed so as to protrude toward the outside of the box at a position to the right of the frame portion 107b1 on the outer surface of the second box part 10b. The claw portion 107b2 enters the hole portion 107a1 of the temporary joint 107a of the first box part 10a.

The lid 20 is a cover that opens and closes the opening 12 of the box body 10. The lid 20 is formed in a substantially rectangular shape. The lid 20 is divided into two parts. That is, the lid 20 has a first lid 21 and a second lid 22.

The first lid 21 is a lid part that opens and closes the left half of the opening 12. The first lid 21 is composed of a base material and a cushioning material. The first lid 21 is supported on the first box part 10a of the box body 10 so as to be capable of opening and closing. The first lid 21 opens and closes the left half of the opening 12 by opening and closing around an axis that extends in the front-to-rear direction. The first lid 21 can be opened from a closed position that closes the opening 12 to a fully open position that forms a predetermined angle (e.g., 100°) with respect to the box body 10.

The second lid 22 is a lid part that opens and closes the right half of the opening 12. The first lid 21 is composed of a base material and a cushioning material. The second lid 22 is supported by the second box part 10b of the box body 10 so as to be capable of opening and closing. The second lid 22 opens and closes the right half of the opening 12 by opening and closing around an axis that extends in the front-to-rear direction. The second lid 22 can be opened from a closed position that closes the opening 12 to a fully open position that forms a predetermined angle (e.g., 100°) with respect to the box body 10.

As shown in FIG. 3, the lid device 1 is equipped with an opening/closing mechanism 60 that opens and closes the lid 20 relative to the box body 10. The opening/closing mechanism 60 is capable of opening and closing the first lid 21 and the second lid 22 individually. An opening/closing mechanism 60 is provided at the front and rear of the first lid 21, and at the front and rear of the second lid 22. The pair of front and rear opening/closing mechanisms 60 operate in conjunction with each other. The left and right opening/closing mechanisms 60 also operate independently.

The opening/closing mechanism 60 has an arm member 61 and a biasing member 62. The arm member 61 is a member that connects the box body 10 and the lid 20. One end of the arm member 61 is rotatably supported by the box body 10. The other end of the arm member 61 is fixed to the lid 20. The arm member 61 can rotate relative to the box body 10 around the one end.

The biasing member 62 is a spring member that generates a biasing force that biases the arm member 61 and therefore the lid 20 toward the open position. The biasing member 62 is, for example, a torsion coil spring. One end of the biasing member 62 is supported by the box body. The other end of the biasing member 62 is fixed to the arm member 61. The biasing force of the biasing member 62 is maximum when the lid 20 is in the closed position.

The first lid 21 and second lid 22 of the lid 20 can each be locked closed by a locking member in the closed position. When the first lid 21 and second lid 22 are released from the closed lock by the locking member through an unlocking operation, the arm member 61 rotates due to the biasing force of the biasing member 62, causing the lid 21 and second lid 22 to open toward the open position. In addition, the first lid 21 and second lid 22 each stop operating in the closed position as the operation of the lid 21, 22 or arm member 61 is restricted by a restricting member (not shown).

The first lid 21 and the second lid 22 are closed toward the closed position by the vehicle occupant pressing the lids 21, 22 against the biasing force of the biasing member 62 to rotate the arm member 61 in the opposite direction. The opening/closing mechanism 60 may also be equipped with a damper device to maintain a constant opening/closing speed of the lid 20.

The lid device 1 has a gap 30. The gap 30 is a gap formed between the lid facing portions 21a, 22a where the first lid 21 and the second lid 22 face each other when both the first lid 21 and the second lid 22 are in the closed position. The lid facing portions 21a, 22a are portions that become the side surfaces of the lids 21, 22 when the lids 21, 22 are in the closed position. The lid facing portions 21a, 22a are each formed in a planar shape so as to extend in both the up-down direction and the front-rear direction when the first lid 21 and the second lid 22 are in the closed position. The lid facing portions 21a, 22a are aligned parallel to each other with the gap 30 open when the lids 21, 22 are in the closed position.

The gap 30 is formed to a minimum size (e.g., 3 mm) S that does not interfere with the first lid 21 and the second lid 22 when they are opened and closed between the closed position and the fully open position. As described in detail later, the formation of this gap 30 is achieved by adjusting the distance in the left-right direction (i.e., the direction of contact and separation) between the lid-facing portion 21a of the first lid 21 and the lid-facing portion 22a of the second lid 22 to a predetermined dimension.

The lid device 1 includes a connecting member 40. The connecting member 40 is a member that permanently connects and fixes the first box part 10a and the second box part 10b to each other. The connecting members 40 include a connecting member 40F that is attached to the front surface of the first box part 10a and the second box part 10b, and a connecting member 40B that is attached to the rear surface of the first box part 10a and the second box part 10b. The connecting member 40 permanently connects the first box part 10a and the second box part 10b to each other in a state in which the first box part 10a and the second box part 10b are temporarily connected to each other by the temporary connecting parts 17a and 17b and the left-right distance between the lid facing parts 21a and 22a is adjusted to a predetermined dimension.

The connecting member 40 is a cover member formed in a plate shape. The connecting member 40 has a left-right width within the sum of the left-right width of the first box part 10a and the left-right width of the second box part 10b. The connecting member 40 connects the first box part 10a and the second box part 10b to each other, for example, by tightening a plurality of screws 41 into the first box part 10a and the second box part 10b.

The lid device 1 includes a side panel 50. The side panel 50 is a partition plate that separates the box body 10 side from the passenger seat. The side panel 50 is formed to extend in the front-rear direction. The side panels 50 are arranged on both the left and right sides of the box body 10. The box body 10 is arranged on the rear side of the side panel 50. Vehicle operating systems such as a shift knob and a handbrake, a cup holder, etc. may be arranged on the front side of the side panel 50.

Next, a method of assembling the lid device 1 will be described with reference to FIG.
Before assembling the lid device 1, the components of the lid device 1, namely, the first box part 10a, the second box part 10b, the first lid 21, the second lid 22, the arm member 61, the biasing member 62, the connecting member 40, and the side panel 50, are prepared.

First, the box opposing portions 15 of the first box part 10a and the second box part 10b are opposed to each other, and the first box part 10a and the second box part 10b are provisionally joined to each other at the provisional joints 17a, 17b (see FIG. 7(A)). In this provisionally joined state, the box opposing portions 15 are opposed to each other, the overlapping portions 16 overlap each other, and the two box parts 10a, 10b are allowed to move relative to each other in the left-right direction by an adjustment allowance of the provisional joints 17a, 17b. Then, the first lid 21 is attached to the first box part 10a and supported so as to be rotatable, and the second lid 22 is attached to the second box part 10b and supported so as to be rotatable (see FIG. 7(B)).

Next, with the first box part 10a and the second box part 10b temporarily joined to each other at the temporary joining parts 17a, 17b as described above, the auxiliary jig 70 is placed between the lid facing portion 21a of the first lid 21 and the lid facing portion 22a of the second lid 22, and the auxiliary jig 70 is interposed between the lid facing portion 21a of the first lid 21 and the lid facing portion 22a of the second lid 22 by the closing operation of each of the first lid 21 and the second lid 22 to the closed position (see Figures 7(C) and (D)).

Even if the auxiliary jig 70 is interposed between the lid-facing portion 21a of the first lid 21 and the lid-facing portion 22a of the second lid 22 as described above, before the first box part 10a and the second box part 10b are permanently joined to each other by the joining member 40, the first box part 10a and the second box part 10b are allowed to move relative to each other in the left-right direction by an amount corresponding to the adjustment allowance of the temporary joining parts 17a, 17b.

The auxiliary jig 70 is a plate-like member formed to a constant thickness. The thickness of the auxiliary jig 70 is set to a thickness equivalent to the gap 30. Specifically, the thickness of the auxiliary jig 70 is set to the same as the target value for the size of the gap 30. The thickness of the auxiliary jig 70 may be set to be slightly larger than the target value of the gap 30. This is in consideration of the fact that after the auxiliary jig 70, which is sandwiched between the lid facing portion 21a of the first lid 21 and the lid facing portion 22a of the second lid 22 by the pressing of the pressing jig, is removed from between the lid facing portions 21a and 22a, the first lid 21 and the second lid 22 move relatively in a direction approaching each other due to the disappearance of the auxiliary jig 70.

After the auxiliary jig 70 is interposed between the lid-facing portion 21a of the first lid 21 and the lid-facing portion 22a of the second lid 22 as described above, the first lid 21 and the second lid 22 are advanced in a direction approaching each other by the pressure of a pressing jig (not shown), and move relatively. The pressing by the pressing jig is performed so that a force is applied evenly in the left-right direction from the front end to the rear end of the first lid 21 and the second lid 22. When the first lid 21 and the second lid 22 move relatively by the pressing jig, the first box part 10a and the second box part 10b supported by the two lids 21, 22 move relatively in conjunction with the relative movement.

The above-mentioned relative movement of the first lid 21 and the second lid 22 in the direction toward each other continues until the auxiliary jig 70 is sandwiched between the lid facing portion 21a of the first lid 21 and the lid facing portion 22a of the second lid 22 (see FIG. 7(D)). Then, when the auxiliary jig 70 abuts against the lid facing portion 21a of the first lid 21 and the lid facing portion 22a of the second lid 22 and is sandwiched between the lid facing portions 21a, 22a, the above-mentioned relative movement is stopped.

When the relative movement is stopped, the connecting member 40 then tightens the screws 41 on the front and rear surfaces of the first box part 10a and the second box part 10b to finally connect the first box part 10a and the second box part 10b to each other (see FIG. 7(E)). When the final connection is made by the connecting member 40, the assembly of the lid device 1 is completed.

When the assembly of the lid device 1 is completed, the pressure of the pressing tool is released and the auxiliary tool 70 is removed from between the lid facing portion 21a of the first lid 21 and the lid facing portion 22a of the second lid 22. Note that the first lid 21 and the second lid 22 may be opened to remove the auxiliary tool 70 from between the lid facing portions 21a and 22a.

In the above-mentioned lid device 1, when the first box part 10a and the second box part 10b are temporarily joined to each other by the temporary joining parts 17a and 17b, the distance between the lid facing part 21a of the first lid 21 and the lid facing part 22a of the second lid 22 in the closed position can be adjusted by adjusting the temporary joining parts 17a and 17b. Therefore, after the above-mentioned temporary joining during the assembly of the lid device 1, the first lid 21 and the second lid 22 can move relative to each other in the left-right direction until the size of the gap 30 formed between the lid facing part 21a of the first lid 21 and the lid facing part 22a of the second lid 22 in the closed position becomes equal to the thickness of the auxiliary jig 70, and thus the first box part 10a and the second box part 10b can move relative to each other in the left-right direction.

In the lid device 1 in which assembly is completed, the first box part 10a and the second box part 10b are finally joined to each other by the joining member 40 in a state in which the size of the gap 30 formed between the lid facing portion 21a of the first lid 21 and the lid facing portion 22a of the second lid 22 in the closed position corresponds to the thickness of the auxiliary jig 70. As described above, the thickness of the auxiliary jig 70 is set to the same as the target value for the size of the gap 30. Therefore, when the first box part 10a and the second box part 10b are finally joined to each other, the above-mentioned gap 30 can be formed so that its size is the target value (i.e., the minimum size at which the first lid 21 and the second lid 22 do not interfere with each other during opening and closing operations).

The configuration of this lid device 1 and its assembly method make it possible to fully join the first box part 10a and the second box part 10b to each other while maintaining the size of the gap 30 formed between the lid-facing portion 21a of the first lid 21 and the lid-facing portion 22a of the second lid 22 at the target value (correct size) in the closed position, even if there is assembly variation between the box body 10 and the lid 20 or manufacturing variation in the box body 10 or the lid 20.

Therefore, even if there are the above-mentioned assembly variations and manufacturing variations, the gap 30 between the lid facing portions 21a, 22a when the first lid 21 and the second lid 22 are in the closed position can be minimized as much as possible. Therefore, it is not necessary to provide the lid facing portions 21a, 22a with rubber fins or the like to close the gap 30 on the assumption that the size of the above-mentioned gap 30 will be larger than the minimum size, so it is possible to prevent the appearance from becoming worse when the lid is in the open position and to prevent the armrest function of the lid facing portions 21a, 22a from being impaired.

As described above, the first box part 10a and the second box part 10b each have overlapping portions 16 that overlap each other. The width of these overlapping portions 16 in the left-right direction is set so that the overlapping portions 16 always overlap even if the above-mentioned assembly variations and manufacturing variations accumulate. Therefore, even if the above-mentioned assembly variations and manufacturing variations accumulate after the lid device 1 is assembled, it is possible to prevent the formation of a hole (i.e., a gap) that connects the inside of the box to the outside of the box between the first box part 10a and the second box part 10b, and the box body 10 can be sealed.

As described above, the connecting members 40 include connecting member 40F attached to the front surfaces of the first box part 10a and the second box part 10b, and connecting member 40B attached to the rear surfaces of the first box part 10a and the second box part 10b. In this case, the first box part 10a and the second box part 10b are fixed to each other on both the front side and the rear side. This makes it possible to prevent a discrepancy in the size of the gap 30 between the front side and the rear side of the first lid 21 and the second lid 22, and to maintain the size of the gap 30 at a constant target value from the front end to the rear end of the first lid 21 and the second lid 22.

In the above embodiment, the first box part 10a and the second box part 10b are divided at approximately the center of the box body 10, the first box part 10a includes the left half of the storage section 11 and the left half of the opening 12, and the second box part 10b includes the right half of the storage section 11 and the right half of the opening 12. However, the present invention is not limited to this, and the first box part 10a and the second box part 10b may be divided at a position biased to either the left or right side of the box body 10, the first box part 10a includes a portion of the left side of the storage section 11 and a portion of the left side of the opening 12, and the second box part 10b includes the remaining area of the storage section 11 and the remaining area of the opening 12.

In the above embodiment, the first box part 10a and the second box part 10b are divided at approximately the center of the box body 10, and the first lid 21 opens and closes the left half of the opening 12 included in the first box part 10a, and the second lid 22 opens and closes the right half of the opening 12 included in the second box part 10b. That is, the area of the opening 12 included in the first box part 10a and the area of the opening 12 that the first lid 21 opens and closes coincide with each other, and the area of the opening 12 included in the second box part 10b and the area of the opening 12 that the second lid 22 opens and closes coincide with each other.

However, the present invention is not limited to this, and the area of the opening 12 included in the first box part 10a may be different from the area of the opening 12 that the first lid 21 opens and closes, and the area of the opening 12 included in the second box part 10b may be different from the area of the opening 12 that the second lid 22 opens and closes. That is, the area of the opening 12 that the first lid 21 opens and closes may extend over the area of the opening 12 included in the second box part 10b, or the area of the opening 12 that the second lid 22 opens and closes may extend over the area of the opening 12 included in the first box part 10a.

In the above embodiment, the temporary joint 17a is integrally formed with the first box part 10a, and the temporary joint 17b is integrally formed with the second box part 10b, and both temporary joints 17a, 17b remain in the first box part 10a or the second box part 10b even after the assembly of the lid device 1 is completed. However, the present invention is not limited to this, and may be applied to a configuration in which the temporary joints 17a, 17b are detachably attached to the first box part 10a and the second box part 10b, and are removed from the first box part 10a and the second box part 10b after the assembly of the lid device 1 is completed.

In addition, in the above embodiment, the first box part 10a and the second box part 10b are finally joined to each other by a plate-shaped joining member 40. However, the present invention is not limited to this, and the first box part 10a and the second box part 10b may be finally joined to each other by other methods such as welding.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
