A structure for front side frames of automobile is provided in which since, among first and second bent parts to the rear of a power unit mounting part of the front side frame formed from a tubular hollow member having a constant cross-section, a first weak part is provided in the vicinity of the rear-side second bent part, and a second weak part is provided in the vicinity of a third bent part, which is bent convexly outward in the vehicle width direction in the power unit mounting part, when an automobile is involved in a frontal collision, it becomes possible for the front side frame formed from the tubular hollow member and having high strength to bend via the first weak part and also via the second weak part, thereby enabling the impact absorption stroke to be increased and the effect in absorbing collision energy to be enhanced.
