Document Type and Number:
WIPO Patent Application WO/2015/162829
Kind Code:
A1
Abstract:
Disclosed is a ventilation device (10, 30, 50, 70) for discharging water vapor from the interior (8) of a housing of a vehicular lamp (1) to the outside of the housing (2), wherein: a ventilation path that is bent and is in communication with a ventilation opening (9) 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, fogging clearability inside the housing is improved while preventing the intrusion of liquid water and external substances by employing said ventilation path having a bent part.
