PROBLEM TO BE SOLVED: To provide a hub unit that can suppress the corrosion of a track member even if an inexpensive steel knuckle is adopted.SOLUTION: A hub unit includes: a vehicle body mounting flange for mounting a knuckle 60; a steel outer track member having an inner periphery track surface; an inner track member having an outer periphery track surface; a rolling element disposed between the inner periphery track surface of the outer track member and the outer periphery track surface of the inner track member; and an annular member 50 fit in an inner periphery surface of the knuckle 60, abutted to one side of an end surface of the outer track member in an axial direction, and comprised of a material of which the ionization tendency is higher than that of the outer track member. |
