以上詳述したように、本実施形態によれば、隅柱部２に連結リブ２７を設け、中間柱部３に第１連結リブ３８及び第２連結リブ４１を設けることにより、連結リブ２７、第１連結リブ３８、及び、第２連結リブ４１そのものによる隅柱部２及び中間柱部３の強度等の向上が図られるだけではなく、連結リブ２７、第１連結リブ３８、及び、第２連結リブ４１を介して外周壁部１１、上部桟１３、及び、下部桟１４を好適に協働させて隅柱部２及び中間柱部３に作用する応力に対応することが可能となる。従って、パレット１の上下方向における圧縮強度、及び、フォークが隅柱部２及び中間柱部３（対象壁部１２）に衝突した場合等の衝撃強度の低下を抑止しつつ、連結リブ２７、第１連結リブ３８、及び、第２連結リブ４１の全体を単なる板状とする場合に比べてパレット１の軽量化を図ることができる。特に、外周壁部１１において開口部を設ける（例えば、隅外壁構成部２１、中間外壁構成部３１を枠状とする）必要がなく、パレット１が圧縮荷重を受けたり、隅柱部２及び中間柱部３にフォークが衝突したりした場合に、隅柱部２及び中間柱部３の外周壁部１１が変形及び損傷するといった事態をより確実に抑止することができる。さらに、パレット１の外周面において、情報を表示する面を確保したり、フック等を引っ掛ける孔部６１を形成しつつ当該孔部６１周辺部の強度・剛性を確保したりすることができる。加えて、内側垂直接続リブ２８は、上部桟１３及び下部桟１４の延在方向における中間位置と連結されており、上部桟１３及び下部桟１４の変形や損傷等を連結リブ２７によってより効果的に抑制することができる。従って、上部桟１３、下部桟１４、内側垂直接続リブ２８、及び、水平接続リブ２９等が相互に補強し合うように効率的に配置され、隅柱部２及び中間柱部３の強度等を確保しつつ軽量化を図るといった作用効果がより顕著に奏される。 As described in detail above, according to the present embodiment, the connecting ribs 27 are provided on the corner pillars 2, and the first connecting ribs 38 and the second connecting ribs 41 are provided on the intermediate pillars 3, whereby the connecting ribs 27, Not only can the strength of the corner post 2 and the intermediate post 3 be improved by the first connecting rib 38 and the second connecting rib 41 themselves, but also the connecting rib 27, the first connecting rib 38 and the second connecting rib 38 can be The external wall portion 11 , the upper crosspiece 13 , and the lower crosspiece 14 can be preferably cooperated with each other via the connecting ribs 41 to cope with the stress acting on the corner post portion 2 and the intermediate post portion 3 . Therefore, the compression strength of the pallet 1 in the vertical direction and the impact strength when the fork collides with the corner post 2 and the intermediate post 3 (target wall portion 12) are suppressed, and the connecting ribs 27 and the third The weight of the pallet 1 can be reduced as compared with the case where the first connecting rib 38 and the second connecting rib 41 are entirely plate-shaped. In particular, there is no need to provide an opening in the outer peripheral wall portion 11 (for example, the corner outer wall forming portion 21 and the intermediate outer wall forming portion 31 are frame-shaped), and the pallet 1 receives a compressive load, and the corner post 2 and the intermediate When a fork collides with the column portion 3, deformation and damage of the outer peripheral wall portion 11 of the corner column portion 2 and the intermediate column portion 3 can be more reliably prevented. Further, it is possible to secure a surface for displaying information on the outer peripheral surface of the pallet 1, and to secure the strength and rigidity of the periphery of the hole 61 while forming the hole 61 for hooking a hook or the like. In addition, the inner vertical connection rib 28 is connected to an intermediate position in the extending direction of the upper crosspiece 13 and the lower crosspiece 14, and the connection rib 27 effectively prevents deformation, damage, etc. of the upper crosspiece 13 and the lower crosspiece 14. can be suppressed to Therefore, the upper crosspiece 13, the lower crosspiece 14, the inner vertical connecting rib 28, the horizontal connecting rib 29, etc. are efficiently arranged so as to mutually reinforce each other, and the strength of the corner post 2 and the intermediate post 3 is increased. The operational effect of achieving weight reduction while ensuring the strength is exhibited more remarkably.

Since the intermediate inner wall second component portion 33) is connected to a predetermined intermediate portion in the extending direction of the upper side portion, the deformation of the target wall portion 12 is prevented by the connecting ribs 27, the first connecting ribs 38, and the second connecting ribs. It can be suppressed more effectively by the rib 41 . Furthermore, the horizontal connection rib 29 extends in a direction substantially orthogonal to the upper rails 13 (the target upper rail 25, the target first upper rail 36, and the target second upper rail 39). It connects with the upper crosspiece 13 at the shortest distance. Therefore, it is possible to reduce the weight of the connecting rib 27, the first connecting rib 38, and the second connecting rib 41 themselves.

None. Therefore, relatively large openings corresponding to the connecting ribs 27, the first connecting ribs 38, and the second connecting ribs 41 are formed in the mounting surface 8 of the pallet 1 on which the articles are mounted. It is possible to avoid a situation in which a part of the article is immersed in the object.

さらに、連結リブ２７、第１連結リブ３８、及び、第２連結リブ４１の外側垂直接続リブ３０の幅は、内側垂直接続リブ２８の幅よりも大きく構成されている。このため、パレット１の重量化を抑制しつつ、外周壁部１１の補強をより一層図ることができ、フォークとの接触により外周壁部１１が損傷する等の事態をより確実に防止することができる。 Furthermore, the width of the outer vertical connecting ribs 30 of the connecting ribs 27 , the first connecting ribs 38 and the second connecting ribs 41 is configured to be larger than the width of the inner vertical connecting ribs 28 . Therefore, it is possible to further reinforce the outer peripheral wall portion 11 while suppressing the increase in weight of the pallet 1, and to more reliably prevent situations such as damage to the outer peripheral wall portion 11 due to contact with the forks. can.
