PURPOSE: A frame structure for a streamlined vehicle is provided to improve safety by dropping weight of a chassis downward caused by decreased pressure. CONSTITUTION: A middle portion of a frame is formed as a streamlined shape of a round type. An auxiliary frame is mounted in the middle of a lower portion of a chassis by having a round shape of the streamlined shape. The frame is integrated with the auxiliary frame to from a middle portion of the round shape. The round shape of the middle portion in the chassis changes speed of air current induced into a gap between a lower face of the chassis and a ground in travelling a vehicle. The speed of the air current in the streamlined middle portion of the chassis is faster than the speed of the air current of rear/front portions of the chassis. Thereby, the streamlined middle portion of the chassis drops pressure to absorb weight of the chassis. Moreover, a frame structure for the streamlined vehicle improves travelling safety.
