A vehicle driving force control device having a device. (2) A driving wheel slip control valve is disposed in a connecting pipe connecting the driving wheel slip control pressure source and the second chamber, and the driving wheel slip control valve and the second chamber are connected. A switching valve is disposed in the connecting pipe line, allowing free communication until the output pressure of the drive wheel slip control valve reaches a predetermined pressure, and allowing only limited communication when the pressure exceeds the predetermined pressure. A vehicle driving force control device comprising the anti-skid device according to item 1 above.
