機構。 When the center axis moves in the anti-yack direction, the restraining force by the collar disappears, and at the same time the collet expands in the radial direction due to the spring force, and the pull stud of the tool holder is anti-yacked. A guide body with an inclined surface is provided corresponding to the inner corner of the tip of the collet to guide the collet in the opening direction and anti-yack the collet which is not anti-yacked due to the movement of the central axis in the anti-yack direction due to breakage of the spring or the like. The forced opening mechanism of the collect chuck is characterized by:
