Abstract

Provided is a heat dissipating structure of a vehicle light, said heat dissipating structure making it possible to obtain sufficient heat dissipating efficiency, while reliably preventing entry of a foreign material from the outside. The present invention is characterized by being provided with: a housing H2 having a bulb B2 as a light source attached thereto; an inner upright wall 28a and an outer upright wall 28b, which are formed to protrude at positions surrounding an attaching area T of the bulb B2, said positions being at the rear of the housing H2; and a socket cover S2 that is attached covering the upright walls (28a, 28b). The present invention is also characterized in that: a heat dissipating space W of the light source is formed inside of the upright walls (28a, 28b) and the socket cover S2; and the upright walls (28a, 28b) have ventilation holes (h1-h4) formed therein so as to open the heat dissipating space W to the outside.
