A through hole 22a that causes the brake chamber B to communicate with the final chamber F of the wheel hub 30 is provided in the spindle case 20 and when an axle shaft 1 rotates, oil in the brake chamber B is supplied inside the final chamber F through the through hole 22a by action of centrifugal force due to rotation of a brake mechanism 80.",
