Abstract
A turret tool holder, having structure capable of easily avoiding unnecessary free rotation of a turret, is provided. When a linearly movable shaft is moved toward a turret head section by driving a servomotor, an annular movable coupling element arranged in the turret begins to disengage from an annular fixed coupling element fixed to a support. While the movable coupling member is still engaged with the fixed coupling member, clutch teeth of a clutch member are engaged with other clutch teeth. Therefore, even when the annular movable coupling element is disengaged from the annular fixed coupling element, the turret is prevented from freely rotating by the engaged clutch teeth.
