Abstract
Abstract Disclosed herein is an air intake device for a compartment of automotive vehicle provided with a transversely elongated space between a rear end portion of an engine hood panel and a substantially horizontal plate of a cowl outer panel for inducing air to a compartment therefrom. The improvement comprises a windshield lower moulding plate arranged above the horizontal plate of the cowl outer panel in such a manner that it strides across a lower end portion of a windshield glass and extends transversely from one of fender panels of the vehicle to another, a second tube provided between the windshield lower moulding plate and the horizontal plate of the cowl outer panel to communicate with first tubes defined inside of the fender panels and an air inducing aperture opened through the horizontal plate covered with the windshield lower moulding plate. With this arrangement, even when the space is covered with snow, the second tube and the air inducing apertures are prevented from being blocked by snow and accordingly, air may be readily induced to the compartment.
