摘要:PROBLEM TO BE SOLVED: To provide a vehicle body frame capable of realizing light weight while ensuring rigidity of a rear frame. SOLUTION: The vehicle body frame is provided with a head pipe 3 steerably supporting a handle 10 to left and right sides; a main frame 5 extending from the head pipe 3 to a pivot part 5p for supporting a rear wheel 11; and a rear frame 7 extending from the main frame 5 to above the rear wheel 11. The rear frame 7 has left and right rear pieces (side side parts) 7a, 7b; and a rear end cross part (lateral side part) 7c for connecting both rear pieces. At plan view, it forms an annular shape with a rear edge part 5h of the main frame 5 and the left and right rear pieces 7a, 7b of the rear frame 7 and the rear end cross part 7c form a curved shape opened toward the inner side.
