To provide a waterproof housing with high waterproof performance, which can be manufactured with a simple metal mold.SOLUTION: A waterproof housing 10 comprises: a housing 13 that houses a circuit configuration 11 in which a circuit is formed; and a cylindrical ventilation tube 30 projected to an inner direction of the housing 13 from an inner surface of the housing 13, and communicating the inner side and an outer side of the housing 13. The ventilation tube 30 includes: an inner side open part 31 that opens to the inner side of the housing 13; an outer side open part 32 that opens to the outer side of the housing; and a plurality of shield plates 35 and 36 that is projected to the inner direction of the ventilation tube 30 from the inner surface of the ventilation tube 30. Each of the plurality of shield plates 35 and 36 is arranged at a position different in a cylindrical axial direction of the ventilation tube 30 so as not to be overlapped with each other in view of the cylindrical axial direction, and an inner space of the ventilation tube is blocked by the plurality of shield plates 35 and 36 in view of the cylindrical axial direction.SELECTED DRAWING: Figure 7
【課題】防水性能が高く、簡易な金型で製造できる防水筐体を提供する。【解決手段】防水筐体10は、回路が形成された回路構成体11を収容するハウジング13と、ハウジング13の内面からハウジング13の内方に突出するとともに、ハウジング13の内側と外側とを連通する筒状の通気筒30と、を備え、通気筒30は、ハウジング13の内側に開口する内側開口部31と、ハウジングの外側に開口する外側開口部32と、通気筒30の内面から通気筒30の内方に突出する複数の遮蔽板35,36と、を有し、複数の遮蔽板35,36のそれぞれは、通気筒30の筒軸方向において異なる位置に、かつ、筒軸方向から視て互いに重畳しないように配されており、筒軸方向から視て、通気筒の内部空間が複数の遮蔽板35,36によって塞がれている。【選択図】図7
