The invention provides a tool holder and a tool holder attachment structure realizing two-side positioning state when a spindle is rotating. The tool holder attachment structure includes a spindle (10) and a tool holder (20). The spindle has a tip end face (12b) and a tapered hole (11). The tool holder has a tapered shank portion (21) and a flange end face (23). In a clamped state, there is a clearance (D1) of a predetermined size between the flange end face of the tool holder and the tip end face of the spindle. As the spindle is rotated, the tapered hole of the spindle is slightly expanded by a centrifugal force caused by rotation of the spindle, and the presence of this clearance allows the tapered shank portion to be further drawn into the tapered hole so that the flange end face of the tool holder closely contacts the tip end face of the spindle, and the tapered shank portion is closely fitted in the tapered hole, whereby two-face restraint is implemented.
