を設けたことを特徴とする工具クランプ装置。 A collet that is located inside the spindle and grips the pull stud of the tool with a plurality of claws arranged annularly on the tip side, and a shaft that is integrally connected to the collet and presses the pull stud to project the tool from inside the spindle. and a drive member for reciprocating the collet and the shaft within the main shaft, wherein an elastic member located between the claws of the collet and installed on the shaft is used to clamp the base end of the shaft in the radial direction. When the part is pressed, a fulcrum serving as a center of rotation is formed between the base end and the distal end, and an auxiliary collet is formed such that the distal end always grips the pull stud by the pressing force of the elastic member. A tool clamp device characterized in that it is provided with a tool clamp device.
