Abstract

See full text

A tool holder includes a tubular body having a shank on a first axial end portion, a tool gripping portion on a second axial end portion, and an elastic segment interposed between the shank and the tool gripping portion in the axial direction of the body. The elastic segment is more elastically deformable along the axial direction and around a circumferential direction of the tubular body than the shank and the tool gripping portion owing to a plurality of voids that extend through the elastic segment from an outer peripheral side of the tubular body to an inner peripheral side of the tubular body. Each of the voids includes segments that extend around the circumferential direction and along the axial direction of the tubular body.
