態とされている。DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS. 1 to 4. The engine (1) is installed between side members (3, 3) arranged on the left and right of the floor of a vehicle body such as an automobile. It is installed on the engine mount member (4) being handed over, and the transmission (2) is installed below the engine (1).
The engine under cover (15) is attached to the top. The engine undercover (15) is a cover body (16).
And a wind guide duct (17) arranged on the front side of the upper surface of the cover body (16), the cover body (16) being bridged between the left and right side members (3, 3). ) Are fixed by bolts (19) and nuts (20), and the air guide duct (17) is connected to the inside of the left and right side members (3, 3) through a communication port (21). As shown in FIG. 4, the bottom portions of the side members (3, 3) are fixed by being sandwiched by double flanges (22, 23). And the air duct
On the rear surface of the (17), there is provided a ventilation port (25) in which a wire net (24) is stretched. Furthermore, inside the side members (3, 3), as shown in FIG. 3, a guide plate (26) is provided behind the communication port (21), and the guide plate (26) is inclined forward. It is said to have been done.
