PROBLEM TO BE SOLVED: To provide a waterproof cover capable of reliably preventing damage of a filter with a simple structure.SOLUTION: A waterproof cover has: a lid part 1b which has a vent hole 10 communicating with an inner surface and an outer surface and covers an electronic component; and a filter F which is fixed on an inner surface of the lid part 1b in the state that it faces an inside opening end 10a of the vent hole 10, allows the air to flow, and shields flow of the fluid. On an outer surface of the lid part 1b, a plane region 15 including a surface 14 where an outside opening end 10b of the vent hole 10 is exposed is formed. The plane region 15 forms a part 16 of different height from the surface 14a at a position adjacent to the vent hole 10.SELECTED DRAWING: Figure 3
【課題】簡便な構成で、フィルタの損傷を確実に防止できる防水カバーを提供する。【解決手段】防水カバーは、内面と外面とを連通させる通気孔10を有し、電子部品を覆う蓋部1bと、通気孔10の内側開口端部10aに対向した状態で蓋部1bの内面に固定され、空気の流通を許容しつつ液体の流通を遮断するフィルタFと、を備え、蓋部1bの外面には、通気孔10の外側開口端部10bが露出している面14aを含む面領域15が形成されており、面領域15には、通気孔10と隣り合う位置に面14aと高さの異なる部位16が形成されている。【選択図】図3
