A vehicle body frame structure is applied to a straddle-type vehicle (100) in which a driving power transmission mechanism (104) which transmits rotational power of a driving source (103) to a rear wheel (102) is placed on a first side in a vehicle width direction, with respect to a center line of a vehicle body in the vehicle width direction. The vehicle body frame structure comprises a head pipe (2); and a pair of main frames (3 (3R, 3L)) extending rearward and outward in the vehicle width direction from the head pipe (2) in such a manner that the main frames (3(3R, 3L)) are spaced apart from each other in the vehicle width direction. The pair of main frames (3(3R, 3L) include portions (45R, 45L), respectively, facing the driving power transmission mechanism (104) in the vehicle width direction, and the portion (45R) facing the driving power transmission mechanism and being located on a second side in the vehicle width direction has a stiffness lower than that of the portion (45L) facing the driving power transmission mechanism and being located on the first side in the vehicle width direction.
