The engine room 2 and the air passage 3 are isolated from each other by means of an engine room front panel 4, and hereat an interconnecting hole 17 interconnecting both 2 and 3 through is installed. In this interconnecting hole 17, there is provided with a platelike valve 18 opening or closing the interconnecting hole 17. The valve 18 is made up of synthetic resin of rubber or the like and so designed as to open the interconnecting hole 17 with the wind pressure of air flowing in the air passage 3. |
