A seal cover includes a cylindrical part which is fixed to an outer peripheral surface of an axle, a flange part which is opposed to an end surface in an axial direction of a housing, interposing a small clearance, and a deflector part which is opposed to an outer peripheral surface of the housing, interposing a small clearance. A passage through which muddy water or the like arrives at an annular clearance from an exterior of a vehicle can be formed of the small clearances, and the passage can be made long. Because an overlapping amount between the deflector part and the outer peripheral surface of the housing can be secured, the muddy water or the like which has been splashed by a wheel and flowing from an outer peripheral side of the housing to an inner peripheral side can be made difficult to intrude into a space.
