Abstract: A porous polytetrafluoroethylene (PTFE) membrane of the present disclosure is a membrane having an average fibril length of 50 μm or more, having an average node length 5 or more times larger than the average fibril length, and having an average node area ratio of 5% or less. The porous PTFE membrane of the present disclosure, when attached as a waterproof air-permeable membrane to a housing of an electrical component or electrical device, allows water vapor residing inside the housing to be quickly discharged out of the housing.

Abstract: A porous polytetrafluoroethylene (PTFE) membrane of the present disclosure has a water vapor permeability, as measured according to Japanese Industrial Standard (JIS) L 1099 (method B-1), of 150000 g/(m2·day) or more in a thickness direction of the membrane. The porous PTFE membrane of the present disclosure, when attached as a waterproof air-permeable membrane to a housing of an electrical component or electrical device, allows water vapor residing inside the housing to be quickly discharged out of the housing.

Abstract: A lamp chamber (110) includes: a first lamp chamber (110A) located in a forward direction from a first reference plane (P1) and inwardly of a second reference plane (P2) in a width direction of a vehicle; and a second lamp chamber (110B) located in a rearward direction from the first reference plane (P1) and outwardly of the second reference plane (P2) in the width direction of the vehicle. A headlamp (101) includes: a first vent member (105) attached to a first opening portion (102A) provided in a region of a housing (102) facing the first lamp chamber (110A); and a second vent member (106) attached to a second opening portion (102B) provided in a region of the housing (102) facing the second lamp chamber (110B). The vent members (105, 106) each include a waterproof air-permeable body. The air permeability value of the first vent member (105) is higher than the air permeability value of the second vent member (106).

Abstract translation: 灯室（110）包括：第一灯室（110A），其位于车辆宽度方向上从第一参考平面（P1）向前方并位于第二参考平面（P2）的内侧; 以及第二灯室（110B），其在所述车辆的宽度方向上从所述第一基准面（P1）向后方位于所述第二基准面（P2）的外侧。 前照灯（101）包括：附接到设置在面对第一灯室（110A）的壳体（102）的区域中的第一开口部分（102A）的第一通风口构件（105） 以及附接到设置在面向第二灯室（110B）的壳体的区域中的第二开口部分（102B）的第二排气构件（106）。 排气构件（105,106）各自包括防水透气体。 第一排气构件（105）的透气度值高于第二排气构件（106）的透气度值。
