PROBLEM TO BE SOLVED: To prevent a jack knife phenomenon and projection to a tow tractor by a vehicle to be towed in braking during downhill traveling, in a combination vehicle for rotatably supporting the vehicle to be towed by taking a connecting point set in the tow tractor as the center. SOLUTION: This braking force control device is provided with a means 29 for detecting the downhill traveling state of a vehicle, means 1, 27 for controlling the brake timing of the vehicle to be towed in braking during downhill traveling so that it may be earlier than the brake timing of the tow tractor with the time difference corresponding to the gradient of a downhill, a means 1 for finding total braking force according to the brake operating amount, and means 1, 28 for controlling a distribution rate of total braking force to the vehicle to be towed in braking during downhill traveling so that it may be increased more than a reference value on a level road at a rate according to the gradient of a downhill.
