Abstract: There is provided a taper coupling structure in which a taper shaft can easily be fitted in and removed from a hub. In a taper coupling structure 10, a groove 34 serving as a hollowed part is provided in a rear end surface HB of a hub 30. The groove 34 is formed continuously in the circumferential direction and uniformly in the radial direction. In the state in which the taper shaft 20 is fitted in the hub 30, the groove 34 interferes with the taper shaft 20 in the radial direction. An inner shell part 35, which is a portion on the inside of the groove 34 in the radial direction, has a low radial rigidity because of the presence of the groove 34. For this reason, if a force is applied from the hollow portion of a flange part 32 toward the outside in the radial direction, the diameter of the inner shell part 35 is liable to be increased in the radial direction by elastic displacement (deflection).
