連結部材70は、図5及び図6に示すように、上部パネル50の裏面と下部パネル60の裏面とにわたって設けられている。連結部材70は、例えば、当接板71、接続部72及びナット75を有する。連結部材70は、上部パネル50及び下部パネル60のみに接続されている。即ち、連結部材70は、上部パネル50及び下部パネル60のみによって保持されており、他の構造物には支持されていない。
当接板71は、板状をなす部材であって、上部パネル50と下部パネル60との配列方向である上下方向に間隔をあけて、一対が設けられている。一方の当接板71は、上部パネル50の上部側板53の裏面に板面が当接している。他方の当接板71は、下部パネル60の下部側板62の裏面に一方の当接板71が当接している。上下方向に配置される当接板71が上側側板53及び下側側板62と当接する位置は、前後方向において同一である。本実施形態の当接板71は、上記一対を一組として、上部側板53の下端及び下部側板62の上端が延在する方向である前後方向に間隔をあけて二組が設けられている。なお、ナット75を用いずに、当接板71に雌ねじ孔を設けてもよい。
接続部72は、上下に間隔をあけて設けられた一対の当接板71同士を接続する。接続部72の上端には、上部側板53に当接する当接板71の下端が一体に設けられている。接続部72の下端には、下部側板62に当接する当接板71の上端が一体に設けられている。接続部72は、上部パネル50の上部側板53の裏面と下部パネル60の下部側板62の裏面とに跨るようにして、上部側板53の下端と下部側板62の上端との延在方向に棒状に延びている。これによって、接続部72は、当該延在方向に離間して配置された二組の当接板71同士を接続している。
ナット75は、連結部材70の当接板71における上部側板53側及び下部側板62側の面とは反対側の面に、例えば溶接等で一体に固定されている。ナット75の孔部の内面には雌ネジが形成されている。孔部の中心軸線が延びる方向は当接板71の厚さ方向に一致している。当接板71にはナット75の孔部に対応して貫通孔71aが形成されている。当該貫通孔71aの内径は、ナット75の孔部の内径よりも大きく形成されていてもよい。
固定部材80は、上部パネル50のパネル本体51及び下部パネル60のパネル本体61を連結部材70に対して表面側から着脱可能に固定する。固定部材80は、上部パネル50及び下部パネル60と連結部材70との当接部分に設けられている。
作業者が例えばメンテナンス時に上部機器31aや下部機器31bにアクセスする際には、内装カバー40の一部を取り外す。即ち、例えば上部機器31aにアクセスする際には、上部パネル50の各種ボルト52a,53a及び固定部材80を取り外すことで、上部パネル50のみを機器収容部30から取り外す。一方、下部機器31bにアクセスする際には、下部パネル60の各ボルト62a及び固定部材80を取り外すことで、下部パネル60のみを機器収容部30から取り外す。また、上部機器31a及び下部機器31bの双方にアクセスする際にも、上部パネル50及び下部パネル60を取り外す順番の制約なく個別に取り外すことができる。つまり、いずれかのパネルだけを取り外したい場合に、取り外す必要がないパネルはそのままで取り外しの対象となるパネルだけを取り外すことができる。
また、比較的スペースの少ないキャブ1内の空間であっても、パネルが複数に分割されていることで、着脱作業を容易に行うことができる。
上部パネル50及び下部パネル60が取り付けられている際には、これら上部パネル50及び下部パネル60の端部は接続部72の内側に収容されている。そのため、パネル縁部56,66が着脱の妨げになることはない。
また、下部パネル60の着脱を手作業で行う際には、誤って下部パネル60が手から滑り落ちてしまった場合であっても、パネル縁部66が下側の対向面73に引っかかることにより、それ以上の落下を回避することができる。よって、着脱作業の安全性を高めることができる。
以上、本発明の実施の形態について説明したが、本発明はこれに限定されることなく、その発明の技術的思想を逸脱しない範囲で適宜変更可能である。
当該内装カバー40では、互いに隣り合うパネル90のうち上方のパネル90の下端には、パネル縁部92が設けられていない。これによっても上記同様に、美観性や各パネル90を個別に着脱できるといった作用効果を奏する。
当該内装カバー40では、互いに隣り合うパネル90は、いずれもパネル本体91の端部にパネル縁部92を有していない。これによっても上記同様に、美観性や各パネル90を個別に着脱できるといった作用効果を奏する。
