PROBLEM TO BE SOLVED: To provide a wheel support device which can prevent the intrusion of a foreign matter into the device from a clearance of engagement between both side-face splines of the end face of a hub shaft of a hub wheel and the end face of a constant velocity universal joint. SOLUTION: A rolling bearing 20 is arranged at the external peripheral face of the hub shaft 13 of the hub wheel 10 to which a wheel is attached. Both side-face splines 18, 62 for connecting the hub shaft 13 and an outer ring 60 of the constant velocity universal joint 50 are formed in such a manner that the hub shaft and the outer ring can transmit torque by being engaged with each other at the end face of the hub shaft 13 and the end face of the outer ring 60 of the constant velocity universal joint 50. A cylindrical seal member 80 for covering the external peripheries of both side-face splines 18, 62 is arranged so as to straddle a clearance between an inner ring 21 of the rolling bearing 20 and the outer ring 60 of the constant velocity universal joint 50 while keeping a sealed state.
