1. A vehicle braking device comprising:
a first supply device configured to supply brake fluid to a first wheel cylinder;
a first supply path configured to connect the first supply device and the first wheel cylinder; and
a first electromagnetic valve and a second electromagnetic valve which are provided on the first supply path, wherein
each of the first electromagnetic valve and the second electromagnetic valve includes a valve body, a valve seat, and a biasing member for biasing the valve body,
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 to each other, the seating direction being a direction in which the valve body is seated on the valve seat, the brake fluid supply direction being a direction in which the brake fluid flows from the first supply device to the first wheel cylinder 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 as each other, and
the fluid path between the first electromagnetic valve and the second electromagnetic valve in the first supply path is not connected to the wheel cylinder in the vehicle.
