Abstract
A vehicle body frame is formed by a head portion, a main pipe, a center pipe, a pivot frame, lower pipes and a down pipe. The head portion is a casting integrally formed with a head pipe. An oil tank is formed by a main body portion of the head portion, the down pipe, and a joint piece which is connected at a lower end thereof to the lower pipes. A tank space is formed in the main body portion, and a seal wall is integrally formed in the tank space for prohibiting the tank space from communicating with the main pipe. A number of ribs are integrally installed at an inner wall face of the tank space. The oil tank built into the frame of the present invention reduces the number and lengths of welds requiring liquid-tight performance to be as small as possible and as short as possible, and eliminates the need to hermetically seal the main pipe.
