Abstract
A vehicle frame structure includes a pair of main frames, one of the pair of frames extending on left side of a vehicle, and the other on the right side, from the head pipe rearwards in an overall sealed cross sectional structure. At least a portion of each main frame includes a frame upper stage and a frame lower stage, each stage made up of a closed, sealed cross sectional structure. At least a portion of each main frame further includes an outer plate and an inner plate joined into an integrated piece with the frame upper stage and the frame lower stage. The plates are installed so as to extend over both sides of the frame upper stage and the frame lower stage. The frame structure provides a well-balanced high-strength main frame, and high strength in portions which join the main frame and head pipe.
