PROBLEM TO BE SOLVED: To provide a wheel support apparatus capable of excellently draining muddy water entered inside from a meshing clearance of both-side face splines on an end surface of a hub shaft of a hub wheel and an end surface of a sidewall part of a constant velocity joint by the action of centrifugal force. SOLUTION: The hub shaft 13 of the hub wheel 10 attached with a wheel and an outer ring 60 of the constant velocity joint 50 are connected in a torque-transmitting manner. The both-side face splines 18 and 80 for connecting the hub shaft 13 of the hub wheel 10 and the outer ring 60 of the constant velocity joint 50 in the torque-transmitting manner by meshing with each other, are formed on the end surface of the hub shaft 13 and the end surface of the sidewall part 61 of the outer ring 60 of the constant velocity joint 50 butted against this end surface. Among a large number of respective tooth parts 18a and 80a constituting the both-side face splines 18 and 80, at least one tooth part is removed, and a drainage channel 83 is constituted in this removed part 82.
