PROBLEM TO BE SOLVED: To provide a drive force distribution device for a vehicle, which can perform the distribution control of a drive force more properly than a conventional one. SOLUTION: The drive force distribution device for the vehicle includes: a housing 5 which is rotated by the drive force of an engine 102 transmitted via a propeller shaft 106, and has an accommodation space 5a therein; left vane motors 7A, 7B having rotors 8 connected to cam rings 7 which are accommodated in the accommodation space 5a, and rotate integrally with the housing 5, a left-side rear wheel 109 and a right-side rear wheel 109; a variable capacity pump 1 which generates hydraulic pressure by the rotation of the propeller shaft 106; a first hydraulic circuit 21 which feeds hydraulic pressure generated by the relative rotation of the cam ring 7 and the rotor 8 at either of the right and left vane motors 7A, 7B to the other of the right and left vane motors 7A, 7B; and a second hydraulic circuit 22 which feeds the hydraulic pressure of the variable capacity pump 1 to the right and left vane motors 7A, 7B so as to be switchable.
