また、ルーバカバー３は前記屋外用のルーバカバーと図４に示すような屋内用のルーバカバーに相互に変更可能なものとしている。すなわち、本発明に係る電気機器キャビネット用ルーバ装置を風雨に曝される事がない屋内に設置する電気機器キャビネット１００に使用するものとした場合に、ルーバカバー３をサブルーバカバー３１と外側ルーバカバー３２を組み合わせたものでなく、前記サブルーバカバー３１と同様にルーバ取付本体１の円形筒部１１に嵌合して取り付けできる単体よりなるルーバカバー３（３ａ）に交換できるものである。したがって、雨水の浸入の防止に配慮することのない通風のよいガラリを設けたルーバカバー３（３ａ）のみを別異に用意するだけで屋外用と屋内用の双方に使用できるものである。   The louver cover 3 can be changed between the outdoor louver cover and the indoor louver cover as shown in FIG. That is, when the louver device for an electric equipment cabinet according to the present invention is used for an electric equipment cabinet 100 installed indoors that is not exposed to wind and rain, the louver cover 3 is connected to the sub-louver cover 31 and the outer louver cover. 32 can be replaced with a louver cover 3 (3a) made of a single body that can be fitted and attached to the circular cylindrical portion 11 of the louver mounting body 1 in the same manner as the sub-rubber cover 31. Therefore, only the louver cover 3 (3a) provided with a louver with good ventilation without considering the prevention of rainwater infiltration can be used for both outdoor and indoor use.

さらに、図５〜図７に示すように、雌ネジ部２ａ付きの締付部材２の周縁に環状溝部２１を設けて、該環状溝部２１に屋外用のルーバカバー３の外側ルーバカバー３２に変えて下端に通風口７１を設けたフード７をスライドさせて取り付けたものとして屋外用として使用することもできる。この場合、環状溝部２１の溝底部２１ａは円形を形成して連なっているので、フード７の背面両側に内向に折曲形成した係止片部７２、７２は環状溝部２１の対向する両側に位置する円弧点を挟み込むように上下方向にスライドして係止し、また、背面上側に内向き折曲形成した係止片部７３は環状溝部２１の上部に位置する円弧点に係止して取り付けられるものである。   Further, as shown in FIGS. 5 to 7, an annular groove portion 21 is provided on the periphery of the fastening member 2 with the female screw portion 2 a, and the annular groove portion 21 is changed to the outer louver cover 32 of the outdoor louver cover 3. The hood 7 provided with a vent hole 71 at the lower end is slid and attached for outdoor use. In this case, since the groove bottom portion 21a of the annular groove portion 21 forms a circle and is continuous, the locking piece portions 72 and 72 bent inwardly on both sides of the back surface of the hood 7 are positioned on opposite sides of the annular groove portion 21. The latch piece 73 formed by inward bending on the upper side of the back surface is latched and attached to the arc point located at the upper part of the annular groove 21. It is what

このように、フード７は雌ネジ部２ａ付きの締付部材２の周縁に設けた環状溝部２１にスライドさせて取り付けられているので、締付部材２の締付停止位置が異なっても所定の上下方向で取り付けできるものである。また、雌ネジ付きの締付部材２はキャビネット１００の板厚が異なっても常にキャビネット１００の外面に当接したものであるから環状溝部２１のキャビネット外面からの位置は一定であるので同一規格のフードを取り付けできるものである。   In this way, the hood 7 is slid and attached to the annular groove portion 21 provided on the periphery of the fastening member 2 with the female screw portion 2a. It can be mounted vertically. Further, since the fastening member 2 with the female screw always contacts the outer surface of the cabinet 100 even if the thickness of the cabinet 100 is different, the position of the annular groove 21 from the outer surface of the cabinet is constant, so A hood can be attached.
