PROBLEM TO BE SOLVED: To provide a head lamp for a motorcycle efficiently radiating heat generated in a semiconductor light emitting element for cooling.SOLUTION: A base part includes: a base part including a pair of right and left lamp chambers constructed by combination of an outer lens 12 and a housing 16 and a semiconductor light emitting element for emitting direct light transmitted through a first lens 26A and the outer lens and radiated forward, and an optical system is mounted. An outer lens integrally formed including a plurality of radiating fins 44c extending toward the rear of the vehicle includes an extension part 12b extending toward the rear of the vehicle as it goes upward from the top of a transparent part 12a, and is covered with a cowl to form a passage where the travel air flows in a space up to the extension part of the outer lens. An enclosure is disposed at a position at the rear side of the vehicle from the housing so that the travel air flowing in through the passage is directed to the plurality of radiating fins 44c along the enclosure. |
