A vehicle front structure of the present invention has a pair of side
members longitudinally located on right and left sides of a vehicle, and
a pair of sub side members juxtaposed to the respective side members and
adapted to receive a impact load in the event of a frontal collision
after the side members receive the impact load. In this vehicle front
structure, the side members first receive the impact load and then the
sub side members juxtaposed to the side members also receive the impact
load after a certain interval, in collaboration with the side members.
Therefore, vehicle deceleration increases in two stages. Since the
vehicle front structure has such sub side members, the magnitude of
deceleration in the second stage upon collision can be made greater than
that in the first stage, and it becomes feasible to make a decision on
activation of occupant protection apparatus well.
