Abstract
A spindle structure capable of accelerating the flow of a fluid in through holes of a rotor. The spindle structure includes a rotatable rotation part. The rotation part includes a tool holding part provided at an axial direction one end of the rotation part and through holes that penetrate the rotation part and open at the end in the axial direction. Further the spindle structure includes a vane provided in the through holes. When the rotation part rotates, the vane rotates with the rotation part to allow a fluid in the interior of the through holes to flow toward the end in the axial direction.
