The front hood is mounted on the vehicle body to be swung open and closed about a hinge mounted on the vehicle body on the rear side of the rear edge of the front hood. The cowl cover is opened and closed by a driving mechanism comprising a four-bar link mechanism including first and second links each of which is pivoted at one end thereof on a member mounted on the front hood and at the other end on the lower surface of the cowl cover and which extend substantially in parallel spaced from each other in the longitudinal direction of the vehicle body, a driving motor and a connecting mechanism for transmitting the output power of the driving motor to the four-bar link mechanism.
