The door 8 is supported by a frame portion 7b of the front frame 7 so as to be openable and closable by hinges 10 (see FIG. 1) provided at both upper and lower ends on one side of the left and right sides. On the side opposite to the hinge 10, a handle 15 is provided for locking the door 8 in the closed position to the frame portion 7b.

図５〜図７に示すように、背板３には、基板１１の四隅を別々に保持する４つのホルダ１６が固着されている。各ホルダ１６には、基板１１を背板３から浮かせて支持する支持片１７（図６参照）と、基板１１の左右位置を決める規制片１８とが折り曲げられている。また、下側のホルダ１６には基板１１の下端を受ける支承片１９が形成され、上側のホルダ１６に基板１１の上端を掛止するラッチ２０が設けられている。   As shown in FIGS. 5 to 7, four holders 16 for holding the four corners of the substrate 11 separately are fixed to the back plate 3. Each holder 16 is bent with a support piece 17 (see FIG. 6) for supporting the substrate 11 by floating from the back plate 3 and a regulation piece 18 for determining the left and right position of the substrate 11. Further, a support piece 19 that receives the lower end of the substrate 11 is formed in the lower holder 16, and a latch 20 that holds the upper end of the substrate 11 is provided on the upper holder 16.

４つのホルダ１６の近傍において、背板３の四隅には取付穴２３が形成され、取付穴２３を通るアンカーボルト２４（図５参照）にワッシャー２５を介してナット２６を締め付けることにより、背板３が４箇所にて壁面Ｗ（図７参照）に取り付けられる。取付穴２３の周辺には、２本のスリット（長角穴）２７がワッシャー２５の外周位置を平行に延びるように形成され、スリット２７と取付穴２３との間に軟弱部２８が設けられている。   In the vicinity of the four holders 16, mounting holes 23 are formed at the four corners of the back plate 3, and by tightening the nuts 26 through the washers 25 to the anchor bolts 24 (see FIG. 5) passing through the mounting holes 23, the back plate 3 is attached to the wall surface W (see FIG. 7) at four locations. Around the attachment hole 23, two slits (long-angle holes) 27 are formed so as to extend in parallel with the outer peripheral position of the washer 25, and a soft portion 28 is provided between the slit 27 and the attachment hole 23. Yes.

図８に示すように、背板３を凹凸のある壁面Ｗに取り付ける場合は、取付ネジであるナット２６の締付力で軟弱部２８が壁面Ｗの凹凸に馴染むように変形する。軟弱部２８は取付穴２３とスリット２７の間に画定されているため、背板３はスリット２７の内側で局部的に変形し、スリット２７の外側では原形を維持する。したがって、壁面Ｗに凹凸がある造営場合であっても、背板３に対して前枠７を容易に組み付けることができる。   As shown in FIG. 8, when the back plate 3 is attached to the uneven wall surface W, the soft portion 28 is deformed so as to conform to the unevenness of the wall surface W by the tightening force of the nut 26 that is an attachment screw. Since the soft portion 28 is defined between the mounting hole 23 and the slit 27, the back plate 3 is locally deformed inside the slit 27 and maintains the original shape outside the slit 27. Therefore, even if the wall surface W is uneven, the front frame 7 can be easily assembled to the back plate 3.

前枠７を組み付ける前に、図７に示すように、背板３上のホルダ１６に基板１１を取り付け、基板１１に電気機器４０をネジ２２で装着する。こうすれば、基板１１の周囲を開いた状態で、機器装着作業を容易に行うことができる。また、基板１１がホルダ１６の支持片１７により背板３から浮いた状態で支持されているため（図３参照）、基板１１を貫通したネジ２２の先端が背板３に当たるおそれもない。   Before the front frame 7 is assembled, as shown in FIG. 7, the substrate 11 is attached to the holder 16 on the back plate 3, and the electric device 40 is attached to the substrate 11 with the screws 22. In this way, it is possible to easily perform the device mounting operation with the periphery of the substrate 11 opened. Moreover, since the board | substrate 11 is supported in the state which floated from the back board 3 with the support piece 17 of the holder 16 (refer FIG. 3), there is no possibility that the front-end | tip of the screw | thread 22 which penetrated the board | substrate 11 may contact | win the back board 3. FIG.

その後、図２に示すように、背板３に入出線ユニット１３とカバー１４を取り付け、入出線ユニット１３に電線２１を通し、配線を済ませたのちに、前枠７を背板３に組み付ける。この組立状態では、軟弱部２８の作用で背板３が原形を維持し、前枠７に歪みが生じていないため、扉８を前枠７に立て付けよく支持できるとともに、造営後のキャビネット１の外観を見栄えよくすることができる。   After that, as shown in FIG. 2, the input / output unit 13 and the cover 14 are attached to the back plate 3, the electric wires 21 are passed through the input / output unit 13, the wiring is completed, and then the front frame 7 is assembled to the back plate 3. In this assembled state, the back plate 3 maintains the original shape by the action of the soft portion 28 and the front frame 7 is not distorted. Can look good.

特に、この実施例のキャビネット１では、厚さ０．５ｍｍの薄鋼板を使用しているので、背板３と前枠７を軽量化し、組立作業を一人で楽に行うことができるとともに、薄鋼板の可撓性を利用して、軟弱部２８を容易に変形させることもできる。また、軟弱部２８が４分割したホルダ１６の近傍に設けられているので、壁面Ｗの凹凸に合わせ、背板３の四隅をそれぞれ独立して変形させることもできる。   In particular, in the cabinet 1 of this embodiment, since a thin steel plate having a thickness of 0.5 mm is used, the back plate 3 and the front frame 7 can be reduced in weight, and the assembly work can be easily performed by one person. The soft portion 28 can be easily deformed by utilizing the flexibility of the above. Moreover, since the soft part 28 is provided in the vicinity of the holder 16 divided into four parts, the four corners of the back plate 3 can be independently deformed according to the unevenness of the wall surface W.

尚、上記実施例では、キャビネット１を垂直な壁面Ｗに設置しているが、図９に示すように、キャビネット１を水平な造営面Ｓに設置することもできる。この場合は、背板３の底板３３に図５と同じ形状の軟弱部２８を設け、ナット２６の締付力で軟弱部２８を造営面Ｓの凹凸に馴染ませて変形させる。その他、本発明の趣旨を逸脱しない範囲で、キャビネット各部の構成や形状を適宜変更して実施することも可能である。   In the above embodiment, the cabinet 1 is installed on the vertical wall surface W, but the cabinet 1 can also be installed on a horizontal construction surface S as shown in FIG. In this case, the soft portion 28 having the same shape as that of FIG. 5 is provided on the bottom plate 33 of the back plate 3, and the soft portion 28 is deformed by fitting with the unevenness of the construction surface S by the tightening force of the nut 26. In addition, the configuration and shape of each part of the cabinet may be changed as appropriate without departing from the spirit of the present invention.
