PROBLEM TO BE SOLVED: To provide a sub frame of a vehicle capable of ensuring the living space around feet of an occupant in a head-on collision without adversely affecting the maneuverability of the vehicle. SOLUTION: The sub frame 100 of the vehicle is provided on a bottom of an engine room 20 in front of a cabin 10 across the vehicle width direction, and has a frame body part 130 for supporting a power unit 30 to be stored in the engine room 20. The frame body part 130 has a cavity part 150 therein, and has an inclined surface part 160 at the position opposite to the power unit 30 on the upper side in the vehicle vertical direction of the cavity part 150. Since the energy during the head-on collision can be effectively absorbed by the deformation of the sub frame 100, a living space around feet of the occupant during the head-on collision can be ensured without adversely affecting the maneuverability of the vehicle caused by providing a weakened part in a floor panel.
