The present invention relates to a crash box for a vehicle, which can satisfy an RCAR corner test and a center test at the same time through optimization of a cross-sectional shape and application of a reinforcing rib and a pipe tube and further, improve fuel efficiency through reduction of weight. A crash box for a vehicle can include: a front connection portion that is connected to both ends of a back beam of the vehicle; a rear connection portion that is connected to a side member of the vehicle; an intermediate connection portion for connecting the front connection portion and the rear connection portion, which is formed as a hollow box shape and through which a cut cross-section of a heptagonal shape is formed in a vehicle width direction; and a plurality of reinforcement ribs formed in the inner space of the intermediate connection portion.
