PURPOSE: A defroster of a vehicle is provided to properly distribute airflow and wind direction to a windshield glass by differently applying a transmitting density by parts while forming the defroster into a porous body for differentiating blow pressure. CONSTITUTION: A porous defroster body(28) consists of a large density part made of small porous texture for lowering blow transmitting density and a small density part for enlarging slowly blow transmitting density inwardly toward a vehicle. Then blowing is performed with receiving resistance according to transmitting density of middle level through a middle part forming the porous defroster body with hollow porous texture, adjacent with a duct(26). Around the edge of a windshield glass, a small amount of air blow is achieved via a double width part(36) formed in a large volume with the largest transmitting density resistance. Consequently, supply of air blow is performed largely from a center part(W) of windshield glass via the porous defroster body and thus frost elimination and moisture removal are promptly made for readily securing a front view.
