To divide a frame structure body, including a suspension supporting section in a vehicle body frame structure of a vehicle having paired right and left wheels, into a small number of relatively compact frame components, and to reduce the number of steps needed to manufacture a frame. A vehicle body frame structure includes, in a front frame assy, a front suspension supporting section having paired right and left cushion top end supporting parts, paired right and left upper arm supporting parts, paired right and left upper arm supporting parts, paired right and left lower arm supporting parts, and paired right and left lower arm supporting parts. In the vehicle body frame structure, the front frame assy has a configuration which is vertically bisected chiefly into an upper front frame and a lower front frame. The upper front frame includes the right and left cushion top end supporting parts. The lower front frame includes the right and left upper arm supporting parts, the right and left upper arm supporting parts, the right and left lower arm supporting parts, and the right and left lower arm supporting parts.
