Ventilation air intake structure of motor vehicle

Abstract

A ventilation air intake structure of a motor vehicle is shown, which comprises two side panels incorporated with both a cowl top panel and a dash upper panel to define an air box which extends along a rear upper edge portion of an engine room of the vehicle. The cowl top panel has a first opening and the dash upper panel has a second opening which is communicated with a passenger cabin of the motor vehicle. A drain chamber is constituted by the hood ridge reinforcing member and one of the side panels. The drain chamber has a downwardly extending narrower passage which is exposed to the open air at a terminal open end thereof. The dash upper panel is formed with a laterally extending channel which has a shallower end portion which passes under the side panel and is exposed at its terminal end to the narrower passage at a position above the terminal open end of the downwardly extending narrower passage. The second opening of the dash upper panel is positioned higher than the extreme end of the shallower end portion of the channel with respect to the vehicle body.
