PROBLEM TO BE SOLVED: To provide a bearing structure capable of preventing a clearance part between a shank and an inner race from being fixed.SOLUTION: An oil reservoir 19 is formed in a space that is sandwiched between a unit bearing 3 within a hub 2 and a flange part 14a of a drive shaft 14. An oil introduction groove 20, which is elongated in a radial direction of a shank 4 and in which a clearance S formed by clearance-fitting an inner race 5 and the shank 4 communicates with the oil reservoir 19, is formed on a vehicle-width-direction outside pressed surface 5b of the inner race 5. |
