PROBLEM TO BE SOLVED: To provide the excellent air resistance reducing effect with a light device, which reduces the air resistance to be applied to a body such as a truck, at a low cost by providing a baffle plate in the front surface of the body at a position separated at the predetermined distance from the edge of the front surface of the body so as to be extended forward, and forming the front end of this baffle plate with a bending part. SOLUTION: A truck 1 has a van type load carrying platform 3 in the rear of a cab 2, and an air resistance reducing device 4 is arranged over a roof 2a of the cab 2 in front of the front surface 3b of the load carrying platform 3. This air resistance reducing device 4 is formed of a horizontal viscous flap 5 and a pair of vertical viscous flaps 6, which are respectively extended forward from the front surface 3b. The horizontal viscous flap 5 is integrally formed by bending a metal flat plate or the like, and has a horizontal part 5b and a bending part 5c formed by bending a front part of the horizontal part 5b downward at the predetermined angle. The vertical viscous flaps 6 are provided so that the bending parts 6c are obliquely bent toward the center of the load carrying platform 3 in the cross direction. |
