The invention provides a vehicle brake fluid pressure control device capable of freely controlling the acting force of a piston acting on the fluid pressure chamber side of an accumulator. This accumulator for a vehicle brake fluid pressure control device is provided with: a cylinder hole (120) which is formed in a base body (51) of the vehicle brake fluid pressure control device (50) and has a bottom opening in a brake fluid communication path, plugs (130, 230) which close the opening of the cylinder hole (120), pistons (110, 310) which close the opening of the cylinder hole (120), magnets (115, 315) which close the opening of the cylinder hole (120), windings (135, 235) which are wound around the windings (135, 235), and power supply units (136, 236) which are wound around the windings (135, 235); the piston (110, 310) is provided in the cylinder hole (120) so as to be movable in the axial direction (120a) of the cylinder hole (120) and divides the cylinder hole (120) into a hydraulic pressure chamber on the communication path side and a gas chamber on the plug side, the magnet (115, 315) is disposed in the piston (110, 310) and is movable together with the piston (110, 310), and the winding (135, 235) is disposed in a space formed by the cylinder hole (120) and the plug (130, 230) and generates a magnetic field by energization. And power supply units (136, 236) that are connected to the windings (135, 235) and that supply current to the windings (135, 235).
