Abstract

PURPOSE: To automatically increase a chucking force according as a turning force becomes stronger and to facilitate the attachment and detachment of a chucked piece, by utilizing a wedge action on push balls.
CONSTITUTION: The push balls 10 are provided between a pressure reception inside surface 4 and flat surfaces 9 provided on chucking members 6. The wedge action is caused among the balls 10, the inside surface 4 and the flat surfaces 9 in the axial direction to surely chuck the piece by a small operating force. A circumferential wedge effect is also produced among the surfaces 4, 9 and the balls 10 to automatically increase the chucking force according as the turning force applied to the piece becomes stronger. The pushing force on the balls can be weakened to decrease the chucking force.
