A vehicle body frame for a saddle-ride type vehicle is manufactured by laser welding, and has good dimensional accuracy in a vehicle length direction. A pivot frame includes a grooved member, a lid member put on an opening of the grooved member, and laser-weld beads with which this lid member is joined to the grooved member. The molten metal shrinks during its solidification, and shrinkage occurs in the vehicle width direction. However, no shrinkage occurs in the vehicle longitudinal direction. As a result, the distance between a head pipe and a pivot shaft is maintained properly.
