PROBLEM TO BE SOLVED: To suppress the deterioration of a turning movement and to reduce a speed as requested by a driver when a rear-wheel slippage is excessive in a rear-wheel-drive vehicle. SOLUTION: A braking force controller OF a rear-wheel-drive vehicle is constructed in such a manner that a rear-wheel slipping rate Slipr is detected (S20), a target slipping rate Rsf for a turning outside front wheel is calculated based on the rear-shell slipping rate (S30), and a braking force for the turning outside front wheel is controlled such that the spilling rate of the turning outside front wheel is equal to the target slipping rate (S40 to 120). Especially, a turning state quantity is detected and the target slipping rate is corrected based on the turning state quantity (S40 to 120). Also, a slipping angleβf is detected for the front wheel, and the target spilling rate is corrected based on the slipping angle of the front wheel such that the target slipping rate is smaller as the slipping angle of the front wheel is larger (S40 to 120).
