ドブラケットを添えて一体に溶着したことにある。In order to achieve the above object, a motorcycle frame according to the present invention has a structure in which a pair of left and right main tubes are welded by welding an outer plate such as a steel plate and an inner plate in the middle. This is because a reinforcing plate is sandwiched between the outer plate and the inner plate at a point and a step is formed on both edges to integrally weld them. In addition, the outer plate and the inner plate are welded together in the middle, and the bridge pieces are laterally penetrated and welded to the rear lower ends of the pair of left and right main tubes, and one end of the bridge piece is projected to the outside of the outer plate of the main tube. Then, the side stand bracket was attached to the bridge piece and the outer plate and welded together.

を防ぐことができる。[Function] Between the outer and inner plates of the pair of left and right main tubes, a reinforcing plate is sandwiched between the outer plate and the inner plate and welded to enhance the strength. It can be Then, by providing a step on both edges of the outer plate, the reinforcing plate, and the inner plate,
Since the welding is performed at the step portion, it is possible to reliably perform the welding without leaving the welding residue. Further, since the side stand bracket is welded to both the bridge piece and the outer plate of the main tube, the welding strength can be sufficient and deformation of the outer plate can be prevented.

して、溶着強度を高くすることができる。As described above, since the present invention is configured as described above, the main tube 1 of the pair of left and right frames can be provided at desired locations where the strength of the outer plate 2 and the inner plate 3 is large. Since the reinforcing plates 10 and 11 are sandwiched and welded to each other, the strength can be increased, and the outer plate 2 and the inner plate 3 of the main tube 1 can be thin as a whole, and the weight can be reduced. Then, the places where the reinforcing plates 10 and 11 are inserted are made smaller in the order of the outer plate 2, the reinforcing plates 10 and 11, and the inner plate 3, and the steps 12 are provided at both end edges, and welding is performed at the steps 12, so the reinforcing plates 10 and 11 are welded. No welding residue is left between the outer plate 2 and the inner plate 3, and the welding strength can be kept high, and deformation of the outer plate 2 and the inner plate 3 can be prevented. Further, one side of the bridge piece 14 welded to the rear lower ends of the left and right main tubes 1 is projected to the outside of the outer plate 2 of the main tube 1, and the side stand bracket 15 is attached to the bridge piece 14 and the outer plate 2 and welded. Therefore, the load of the side stand bracket 15 can be shared by the bridge pieces 14, and the load received by the outer plate 2 can be reduced to prevent the outer plate 2 from being deformed. Then, the welding strength can be increased.
