摘要：
A tool holder is attached to a spindle by the contacting of the projecting cone part and end surface of the tool holder with the recessed cone part and end surface of the spindle respectively. A toroidal cone section is provided on the inner side surface of the recessed cone part of the spindle so as to protrude inward. The diameter of the toroidal cone section is formed smaller than the diameter of the section of the projecting cone part of the tool holder that abuts the toroidal cone section.
