The recessed portion 34 of the present embodiment does not bend the inner wall portion 29, but bends the outer wall portion 31 inward of the lid member 7, and cuts out the lateral wall portion 30 according to the bent shape of the outer wall portion 31. It is formed like this. As shown in FIG. 9, in the present embodiment, the portion of the fixing portion 16 of the beam member 5 that substantially contacts the inner surface of the side wall portion 4 and a part of the fixing member 17 are the lid member 7 in the recessed portion 34. And so as to be accommodated between the side wall portion 4.

尚、低領域部３３は、蓋部材７のうち梁部材５の下面側と対向する範囲だけでなく、その両側方の範囲にまで拡張形成されている。これにより、梁部材５が容器２に取付けられた状態においても、梁部材５の側方（空間）から、低領域部３３を介して、梁部材５の下方（蓋部材７との間）に手を挿入させることが可能となる。 The low region portion 33 is extended not only to a range of the lid member 7 facing the lower surface side of the beam member 5, but also to a range on both sides thereof. As a result, even when the beam member 5 is attached to the container 2, the beam member 5 is placed below the beam member 5 (between the lid member 7) from the side (space) of the beam member 5 via the low region portion 33. It is possible to insert a hand.

また、図５等に示すように、低領域部３３には、ベース部２３から上方に延出し、縦壁部２４と、外周壁部２８（内壁部２９）との間を連結する左右一対の連結縦壁部３７と、一対の連結縦壁部３７の上縁部間を連結する連結天壁部３８とを具備する連結部３６が設けられている。尚、本実施形態の蓋部材７は、長手幅方向中央部を通り、蓋部材７の短手幅方向に延びる仮想直線を中心として線対称形状となっているが、短手幅方向中央部を通り、蓋部材７の長手幅方向に延びる仮想直線を中心とする線対称形状とはなっていない。さらに、上記のように、本実施形態では、蓋部材７を２つ１組で使用する構成であり、蓋部材７の一対の長側辺部のうち、容器２の側壁部４と対向する一方の長側辺部においては、上記のように窪み部３４が形成されるとともに、連結部３６が設けられるものの、相手側の蓋部材７と突き合わせる他方の長側辺部においては、窪み部３４が形成されていない上、連結部３６も設けられていない。 Further, as shown in FIG. 5 and the like, the low region portion 33 extends upward from the base portion 23 and connects the vertical wall portion 24 and the outer peripheral wall portion 28 (inner wall portion 29) to a pair of left and right. A connecting portion 36 including a connecting vertical wall portion 37 and a connecting top wall portion 38 that connects the upper edges of the pair of connecting vertical wall portions 37 is provided. The lid member 7 of the present embodiment has a line-symmetrical shape centered on a virtual straight line that passes through the central portion in the longitudinal width direction and extends in the lateral width direction of the lid member 7, but the central portion in the lateral width direction is formed. As you can see, it does not have a line-symmetrical shape centered on a virtual straight line extending in the longitudinal width direction of the lid member 7. Further, as described above, in the present embodiment, the lid members 7 are used as a set of two, and one of the pair of long side portions of the lid member 7 faces the side wall portion 4 of the container 2. In the long side portion of the above, the recessed portion 34 is formed and the connecting portion 36 is provided, but in the other long side portion that abuts the lid member 7 on the mating side, the recessed portion 34 is provided. Is not formed, and the connecting portion 36 is not provided.

加えて、図６等に示すように、上記ワーク受容部２１に関しても、ベース部２３から上方に突出する部位をワークの上部形状に対応して設けることによって、蓋部材７の下面側に形成されている。また、図５等に示すように、本実施形態では、蓋部材７の各短側辺部に近いワーク受容部２１と、その隣のワーク受容部２１との間の位置に、受容部２２が設けられている。さらに、本実施形態では、蓋部材７のうちワーク受容部２１の天井面を構成している壁部の上面よりも、受容底壁部２５の上面の方が高い位置に設けられている。このため、平面視で、受容部２２と、ワーク受容部２１（ワーク受容部２１が下面側に形成されている部位）とが隣接する部位も存在するが、両者間には、高低差のある受容部２２と、ワーク受容部２１との間を連結する段差部（本例では縦壁部２４）が設けられている。尚、平面視で、受容部２２と、ワーク受容部２１との間にベース部２３が介在する部位に関しては、受容部２２と、ワーク受容部２１との間の上下方向に延びる壁部が段差部に相当する。 In addition, as shown in FIG. 6 and the like, the work receiving portion 21 is also formed on the lower surface side of the lid member 7 by providing a portion protruding upward from the base portion 23 corresponding to the upper shape of the work. ing. Further, as shown in FIG. 5 and the like, in the present embodiment, the receiving portion 22 is located between the work receiving portion 21 near each short side of the lid member 7 and the work receiving portion 21 adjacent thereto. It is provided. Further, in the present embodiment, the upper surface of the receiving bottom wall portion 25 is provided at a higher position than the upper surface of the wall portion forming the ceiling surface of the work receiving portion 21 among the lid members 7. Therefore, in a plan view, there is a portion where the receiving portion 22 and the work receiving portion 21 (the portion where the work receiving portion 21 is formed on the lower surface side) are adjacent to each other, but there is a height difference between the two. A step portion (vertical wall portion 24 in this example) is provided to connect the receiving portion 22 and the work receiving portion 21. In a plan view, with respect to the portion where the base portion 23 is interposed between the receiving portion 22 and the work receiving portion 21, the wall portion extending in the vertical direction between the receiving portion 22 and the work receiving portion 21 has a step. Corresponds to the department.

以上詳述したように、本実施形態によれば、容器２に収容されたワークを覆うようにして蓋部材７を設置し（トレー６を介在させて複数段積み重ねられたワークに蓋部材７を被せ）、蓋部材７の受容部２２に下辺部を挿入させるようにして梁部材５を容器２に取付けることで、ワークの上方への変位が、蓋部材７を介して、梁部材５により規制されることとなる。従って、ワークが容器２に収容されて運搬される際に上下に振動等が発生した場合であっても、ワークが容器２から上方に飛び出して脱落等してしまうといった事態を確実に防止することができる。さらに、梁部材５（の下部）を蓋部材７の受容部２２に収容した相対位置関係とすることで、梁部材５に対する蓋部材７の水平方向における相対変位を規制することができる。従って、蓋部材７の設置状態の安定化等を図ることができ、蓋部材７が容器２に対して相対変位して、ワークに悪影響を与えたり、蓋部材７が容器２から外れてしまったり（蓋部材７が梁部材５とワークとの間から側方にすり抜けてしまったり）するといった事態をより確実に防止することができる。 As described in detail above, according to the present embodiment, the lid member 7 is installed so as to cover the work housed in the container 2 (the lid member 7 is placed on the work stacked in a plurality of stages with the tray 6 interposed therebetween. By attaching the beam member 5 to the container 2 so that the lower side portion is inserted into the receiving portion 22 of the lid member 7, the upward displacement of the work is regulated by the beam member 5 via the lid member 7. Will be done. Therefore, even if vibration or the like occurs up and down when the work is housed in the container 2 and transported, it is possible to reliably prevent the work from jumping upward from the container 2 and falling off. Can be done. Further, by setting the beam member 5 (lower part) in the receiving portion 22 of the lid member 7 in a relative positional relationship, it is possible to regulate the relative displacement of the lid member 7 with respect to the beam member 5 in the horizontal direction. Therefore, it is possible to stabilize the installed state of the lid member 7, and the lid member 7 is displaced relative to the container 2 to adversely affect the work, or the lid member 7 may come off from the container 2. It is possible to more reliably prevent a situation in which the lid member 7 slips sideways from between the beam member 5 and the work.

また、蓋部材７のうち梁部材５の下面側と対向する部位には、受容部２２よりも蓋部材７の外縁部側において、受容底壁部２５よりも下方に位置する低領域部３３が設けられている。このため、蓋部材７の上方に梁部材５を設置する作業や、梁部材５を側壁部４に固定する作業を行う際に、該作業を行う作業者の手や工具等の作業用のスペースを確保することができる。従って、梁部材５を容器２に取付けたり、取外したりする際の作業性の向上を図ることができる。 Further, in the portion of the lid member 7 facing the lower surface side of the beam member 5, a low region portion 33 located on the outer edge portion side of the lid member 7 with respect to the receiving portion 22 and below the receiving bottom wall portion 25 is provided. It is provided. Therefore, when the work of installing the beam member 5 above the lid member 7 or the work of fixing the beam member 5 to the side wall portion 4, a space for work such as hands and tools of the operator who performs the work is performed. Can be secured. Therefore, it is possible to improve workability when attaching or detaching the beam member 5 to or from the container 2.

さらに、低領域部３３に設けられ、縦壁部２４と、外周壁部２８との間を連結する連結部３６が設けられている。このため、蓋部材７の低領域部３３に対応する部位の強度を高めることができ、蓋部材７の変形等を抑止することができる。従って、蓋部材７の変形に起因して受容部２２から梁部材５が抜け出すといった事態を防止することができ、蓋部材７と、梁部材５との位置ずれをより確実に防止することができる。 Further, a connecting portion 36 provided in the low region portion 33 and connecting the vertical wall portion 24 and the outer peripheral wall portion 28 is provided. Therefore, the strength of the portion corresponding to the low region portion 33 of the lid member 7 can be increased, and the deformation of the lid member 7 can be suppressed. Therefore, it is possible to prevent the beam member 5 from coming off from the receiving portion 22 due to the deformation of the lid member 7, and it is possible to more reliably prevent the misalignment between the lid member 7 and the beam member 5. ..

加えて、蓋部材７の外周壁部２８が蓋部材７の内外方向において２層構造とされていることにより、蓋部材７の外周部の強度を高めることができ、蓋部材７の変形等をより確実に防止することができる。また、低領域部３３は、蓋部材７のうち梁部材５の下面側と対向する部位において、外周壁部２８を含む範囲にまで設けられている。従って、梁部材５の着脱作業性の向上を図るといった上記作用効果がより一層奏される。 In addition, since the outer peripheral wall portion 28 of the lid member 7 has a two-layer structure in the inner and outer directions of the lid member 7, the strength of the outer peripheral portion of the lid member 7 can be increased, and the lid member 7 can be deformed. It can be prevented more reliably. Further, the low region portion 33 is provided in a portion of the lid member 7 facing the lower surface side of the beam member 5 to a range including the outer peripheral wall portion 28. Therefore, the above-mentioned effects such as improving the workability of attaching and detaching the beam member 5 are further achieved.

さらに、低領域部３３における外周壁部２８には、低領域部３３の上面側と連続する窪み部３４が設けられている。このため、蓋部材７のうち梁部材５の下面側と対向する部位において、蓋部材７の外周面と、容器２の側壁部４との間に、梁部材５を側壁部４に固定する固定部材１７を設置するためのスペースを確実に確保することができる。特に、窪み部３４が低領域部３３の上面側と連続していることから、梁部材５を側壁部４に固定する作業を行うスペースについてもより確保し易くなる。従って、梁部材５を容器２に取付けたり、取外したりする際の作業性の向上をより一層図ることができる。加えて、蓋部材７の外周面が側壁部４の内面に近接配置される構成においては、蓋部材７の着脱作業に際して、窪み部３４に対し作業者の手やロボットアーム等を挿入して蓋部材７を保持することが可能となり、蓋部材７の着脱作業性の向上等を図ることができる。 Further, the outer peripheral wall portion 28 of the low region portion 33 is provided with a recessed portion 34 continuous with the upper surface side of the low region portion 33. Therefore, in the portion of the lid member 7 facing the lower surface side of the beam member 5, the beam member 5 is fixed to the side wall portion 4 between the outer peripheral surface of the lid member 7 and the side wall portion 4 of the container 2. It is possible to reliably secure a space for installing the member 17. In particular, since the recessed portion 34 is continuous with the upper surface side of the low region portion 33, it becomes easier to secure a space for fixing the beam member 5 to the side wall portion 4. Therefore, it is possible to further improve workability when attaching or detaching the beam member 5 to or from the container 2. In addition, in the configuration in which the outer peripheral surface of the lid member 7 is arranged close to the inner surface of the side wall portion 4, when the lid member 7 is attached / detached, a worker's hand, a robot arm, or the like is inserted into the recessed portion 34 to cover the lid. The member 7 can be held, and the workability of attaching and detaching the lid member 7 can be improved.

また、蓋部材７の下面側にワーク受容部２１が設けられることで、ワークの水平方向への変位、及び、傾倒変位が、蓋部材７を介して、梁部材５により規制されることとなる。従って、ワークの収容状態の安定化等を図ることができ、ワークを安定して運搬等することができる。さらに、受容部２２と、ワーク受容部２１との間には段差部（本例では縦壁部２４等）が設けられている。このため、例えば、受容部２２の底面を形成する壁部（受容底壁部２５）と、ワーク受容部２１の天井面を形成する壁部とが同一高さで、一部が連続して設けられるような構成に比べ、蓋部材７の強度を高めることができる。 Further, by providing the work receiving portion 21 on the lower surface side of the lid member 7, the horizontal displacement and the tilting displacement of the work are regulated by the beam member 5 via the lid member 7. .. Therefore, the accommodation state of the work can be stabilized, and the work can be stably transported. Further, a step portion (vertical wall portion 24 or the like in this example) is provided between the receiving portion 22 and the work receiving portion 21. Therefore, for example, the wall portion (reception bottom wall portion 25) forming the bottom surface of the receiving portion 22 and the wall portion forming the ceiling surface of the work receiving portion 21 are provided at the same height, and a part thereof is continuously provided. The strength of the lid member 7 can be increased as compared with such a configuration.

尚、上記実施形態の記載内容に限定されず、例えば次のように実施してもよい。勿論、以下において例示しない他の応用例、変更例も当然可能である。 The content is not limited to the description of the above embodiment, and may be implemented as follows, for example. Of course, other application examples and modification examples not illustrated below are also possible.

（ａ）図１１に示すように、受容部２２が階段状をなす階段部４１を備えるように構成してもよい。また、図１２に示すように、受容部２２が上方に向けて該受容部２２を広げる方向に傾斜して延びる傾斜部４２を備えるよう構成してもよい。 (A) As shown in FIG. 11, the receiving portion 22 may be configured to include a stepped portion 41 having a stepped shape. Further, as shown in FIG. 12, the receiving portion 22 may be configured to include an inclined portion 42 extending in an inclined direction in which the receiving portion 22 is spread upward.

これらの構成を採用する場合、容器２に収容されるワークの高さにばらつきが生じた場合であっても、梁部材５の容器２への取付位置を微調整し、梁部材５と、受容部２２（階段部４１、又は、傾斜部４２）とが当接、又は、近接する相対位置とすることができる。つまり、容器２に収容されるワークの高さが設計の高さよりも低くなった場合、梁部材５と、蓋部材７とが上下に離間し、梁部材５の受容部２２への挿入長が短くなって、蓋部材７（ワーク）の上下の振動等を抑え難くなり、蓋部材７が外れ易くなる、或いは、ワークが位置ずれする等ことが懸念されるが、梁部材５の取付位置を、階段部４１、又は、傾斜部４２のより高い位置と当接し得るように調整することで、かかる懸念を払拭することができる。また、容器２に収容されるワークの高さが設計の高さよりも高くなった場合、梁部材５と、ワークとの間に蓋部材７を設置するスペースを確保できなくなってしまうことが懸念されるが、梁部材５の取付位置を、階段部４１、又は、傾斜部４２のより低い位置と当接し得るように調整することで、かかる懸念を払拭することができる。特に、ワークが（トレー６を介在させて）複数段積まれて容器２に収容される場合や、容器２が複数種類のワークの運搬に使用される場合等には、ワークの高さにばらつきが生じ易く、上記の作用効果がより顕著なものとなる。従って、利便性の向上、及び、汎用性の向上等を図ることができる。 When these configurations are adopted, even if the height of the work accommodated in the container 2 varies, the mounting position of the beam member 5 to the container 2 is finely adjusted to receive the beam member 5 and the receiving position. The relative positions may be such that the portions 22 (staircase portions 41 or inclined portions 42) are in contact with or close to each other. That is, when the height of the work accommodated in the container 2 becomes lower than the designed height, the beam member 5 and the lid member 7 are separated from each other in the vertical direction, and the insertion length of the beam member 5 into the receiving portion 22 is increased. As the length becomes shorter, it becomes difficult to suppress the vertical vibration of the lid member 7 (work), and there is a concern that the lid member 7 may come off easily or the work may be misaligned, but the mounting position of the beam member 5 may be changed. The concern can be dispelled by adjusting the staircase portion 41 or the inclined portion 42 so as to be in contact with the higher position. Further, if the height of the work accommodated in the container 2 becomes higher than the design height, there is a concern that it will not be possible to secure a space for installing the lid member 7 between the beam member 5 and the work. However, such a concern can be dispelled by adjusting the mounting position of the beam member 5 so that it can come into contact with the lower position of the staircase portion 41 or the inclined portion 42. In particular, when the workpieces are stacked in a plurality of stages (with the tray 6 interposed therebetween) and accommodated in the container 2, or when the container 2 is used for transporting a plurality of types of workpieces, the height of the workpieces varies. Is likely to occur, and the above-mentioned action and effect become more remarkable. Therefore, it is possible to improve convenience and versatility.

尚、階段部４１、及び、傾斜部４２のうち、梁部材５の下面に対向する（当接し得る）部位により受容底壁部が構成され、側面に対向する（当接し得る）部位により規制部が構成される。また、階段部４１、又は、傾斜部４２を備える構成を採用する場合には、容器２に２本の互いに平行して延在する梁部材５が設けられ、梁部材５の延在方向に対して直交する方向において、一方の梁部材５の一側面側と、当該一方の梁部材５に対応する受容部２２（階段部４１、又は、傾斜部４２）とが当接、又は、近接して配置され、他方の梁部材５の他側面側と、当該他方の梁部材５に対応する受容部２２（階段部４１、又は、傾斜部４２）とが当接、又は、近接して配置されることとしてもよい。この場合、蓋部材７の水平方向の位置ずれをより確実に防止することができる。 Of the staircase portion 41 and the inclined portion 42, the receiving bottom wall portion is formed by the portion facing (possibly abutting) the lower surface of the beam member 5, and the regulating portion is formed by the portion facing (possibly abutting) the side surface. Is configured.
