A rotary ring (12) of a hub unit (10) has an annular first end face (25) on one side in the axial direction, and an outer ring (33) of a joint (30) has an annular second end face (38) on the other side in the axial direction. Outer splines (51) are formed in a radially outer-side region of the first end face and outer splines (61) are formed in a radially outer-side region of the second end face. The outer splines of the first end face and the outer splines of the second end face mesh with each other. Inner splines (52) are formed in a radially inner-side region of the first end face and inner splines (62) are formed in a radially inner-side region of the second end face. The inner splines of the first end face and the inner splines of the second end face mesh with each other. |
