PROBLEM TO BE SOLVED: To provide a heat radiation structure of a vehicle lighting fitting which secures high heat radiation performance while securing a required aiming function.SOLUTION: In a vehicle lighting fitting, a light source unit 2 using an LED (a semiconductor light emitting element) 4 as a light source is housed in a lamp room defined by a housing 1 and a lens covering an opening of the housing 1, and the light source unit 2 is supported at the housing 1 by an aiming mechanism so that its position may be adjusted. As a heat radiation structure of the vehicle lighting fitting, a structure, in which the light source unit 2 and the housing 1 are connected by a heat transfer member including a slide mechanism, is adopted. For example, the aiming mechanism is composed of three aiming bolts and the heat transfer member is formed so as to include multiple heat radiation bolts 9 which are similar to the aiming bolts. |
