Summary:To provide a moisture absorption respirator with a simple configuration.SOLUTION: A valve body 38 of a respiratory valve 14 is made of a foam, porous body having a closed-cell structure, a semi-closed-cell structure, an open-cell structure. The valve body 38 normally does not allow air to pass therethrough, but allows air to pass therethrough due to pressure applied to the valve body 38 during a respiratory operation of the oil-filled electrical equipment, thereby implementing the respiratory operation of the oil-filled electrical equipment.SELECTED DRAWING: Figure 4 【課題】簡易な構成の吸湿呼吸器を提供する。【解決手段】呼吸弁１４の弁体３８を、独立気泡構造、半独立気泡構造、連続気泡構造の発泡体、多孔質体とした。当該弁体３８は、通常時は空気を通さず、油入電気機器の呼吸動作時に弁体３８に加わる圧力によって空気を通し、油入電気機器の呼吸動作を実現する。【選択図】 図４
