摘要

PROBLEM TO BE SOLVED: To obtain pressing force for stably pressing a tapered outer peripheral surface of a taper sleeve onto the tapered inner peripheral surface of a tool spindle in a dihedral-constraint-type tool holder. SOLUTION: Many disc springs 82 are combined into a hole 66 having a bottom of a holder body 16, an engaging pin 90 that penetrates through the holder body in the diameter direction and engages with the taper sleeve 18 is energized via a spacer 94 and a pin holding member 92, and the taper sleeve is energized in the direction of separating from the holder body.
