To provide a water-proof type signal control device that prevents water from entering from outside.SOLUTION: A water-proof type signal control device includes: a frame part 1; a control box body 2 to be stored inside the frame part 1; a base body part 3 that is fixed to a lower end of the frame part 1 and can be attached to a support pole P of a traffic signal light; and a covering body part 4 that covers the frame part 1 storing the control box body 2 from above. The covering body part 4 has a hollow square tube shape that covers the frame part 1 from above and has a sealed structure except for an open lower part. In a state in which the frame part 1 is covered by the covering body part 4, at least, there is no possibility that rainwater or the like will invade from above the covering body part 4. Additionally, although air may be compressed in the covering body part 4 and flooded from below the control box body 2 if the signal control device is submerged and the water depth becomes deeper and the water pressure becomes higher, an electronic device is not destroyed by flooding, because the bottom of the control box body 2 is a gap, and an operation part 2b is in an elevated state due to the action of a seesaw side part.SELECTED DRAWING: Figure 1
【課題】外部から水が浸入し難い防水型信号制御機を提供する。【解決手段】防水型信号制御機は、枠部1と、枠部1内に収納する制御箱体2と、枠部1の下端に固定し、交通信号灯の支柱Pに取り付け可能な基台部3と、制御箱体2を収納した枠部1を上方から覆う覆体部4とから構成されている。覆体部4は枠部1を上方から覆う中空の角筒状とされ、開放した下部以外は密閉構造とされている。覆体部4により枠部1を覆った状態では、少なくとも覆体部4の上方から雨水等が侵入する虞れは全くない。また、信号制御機が水没して水深が深くなり、水圧が高くなった場合には、覆体部4内に空気が圧縮されて、制御箱体2の下方から浸水することがあるが、制御箱体2は底部が空隙であり、かつ操作部2bがシーソー辺部の作用により上昇状態であることから、電子機器が浸水により破壊されることはない。【選択図】図1
