Abstract
A vehicular lamp has a lamp body defining therein a lamp chamber, and a light source disposed in the lamp body. An air communication hole is formed in a back plate of the lamp body for producing an air communication passage between a lamp chamber and the air outside of the lamp. An encircle wall which defines the air communication hole projects inward with respect to the lamp chamber.
