Abstract: A vehicle braking device includes a first supply device that supplies brake fluid to wheel cylinders, a first supply path that connects the first supply device and the wheel cylinders, and first and second electromagnetic valves provided on the first supply path. The first electromagnetic valve is disposed on the first supply path such that a seating direction of the first electromagnetic valve and a brake fluid supply direction are opposite each other, the seating direction is a direction in which a valve body is seated on a valve seat, and the brake fluid supply direction is a direction in which the brake fluid flows from the first supply device to the wheel cylinders through the first supply path. The second electromagnetic valve is disposed on the first supply path such that a seating direction of the second electromagnetic valve and the brake fluid supply direction are the same.
