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).
