Abstract: Disclosed is a ventilation device for discharging water vapor from the interior of a housing of a vehicular lamp to the outside of the housing, wherein: a ventilation path that is bent and is in communication with a ventilation opening in the housing is formed; and, up to the terminal end of the ventilation path including the bent part, the ventilation path maintains a minimum cross-sectional area with which it is possible to maintain a fogging reduction rate of 80% or higher in a lapse of 5 minutes. Thus, a defogging property inside the housing is improved while preventing the infiltration of liquid water and external substances by employing the ventilation path having a bent part.

Abstract: The ventilation member of the present invention includes: a support having a through hole serving as a part of an air passage between an interior space and an exterior space of a housing when the support is attached to an opening of the housing; an air-permeable membrane disposed on the support to cover one end of the through hole that opens into the exterior space; and a cover member covering the support over the air-permeable membrane so as to form, between the cover member and the support, a ventilation space serving as a part of the air passage. The support includes a first oil-repellent portion formed around the air-permeable membrane. The first oil-repellent portion is formed by oil-repellent treatment of a part of a first surface of the support. The present invention provides a ventilation member suitable for preventing adhesion of oil to the air-permeable membrane even if the oil enters the inside of the cover member.
