Abstract Translated from Japanese (57)【要約】 【課題】筐体内部の電子部品の損傷を防止し、内圧と外 圧との圧力調整が行える携帯無線機を可能とする。 【解決手段】密閉構造の筐体１１の所要部分に通風孔１ ６を穿設し、該通風孔に焼結金属１８を設けることによ り、防水構造を維持しつつ、内圧と外圧との圧力差が生 じた場合に自ずと圧力調整が行える。 (57) [Problem] To provide a portable wireless device capable of preventing damage to electronic components inside a housing and performing pressure adjustment between an internal pressure and an external pressure. A ventilation hole (1) is provided in a required portion of a housing (11) having a closed structure. By providing the sintered metal 18 in the ventilation holes, the pressure can be automatically adjusted when the pressure difference between the internal pressure and the external pressure occurs while maintaining the waterproof structure.
