<p>PROBLEM TO BE SOLVED: To provide a wheel bearing device with a constant velocity joint capable of surely sealing between an outer cylindrical portion of an outer member and a bowl-like portion of the constant velocity joint at an upper portion, and making a discharge space hardly clogged.SOLUTION: A wheel bearing device 20 with a constant velocity joint includes an outer member 30, an inner member 21 disposed at an inner peripheral side of the outer member 30, and a plurality of rolling elements 40, 41 rolling between the outer member 30 and the inner member 21. The outer member 30 is provided with an outer cylindrical portion 31 projecting to one side in the axial direction with respect to the inner member 21, a mounting hole 26 is coaxially formed on an inner periphery of the inner member 21, shaft portions 76, 77 of the constant velocity joint 70 are fitted to the mounting hole 26, and a bowl-like portion 71 of the constant velocity joint 70 is disposed at an inner peripheral side of the outer cylindrical portion 31. A labyrinth seal 45 is formed between the outer cylindrical portion 31 and the bowl-like portion 71 at an upper portion, and a discharge space 46 for discharging sludge is formed at a lower portion.</p> |
