ツクの着脱機構。 A finger chuck that holds a bar, a spindle connected to this finger chuck, a cylindrical casing into which this spindle is rotatably inserted and attached to the tip of the feed pipe, and a a cap that is slidable in the axial and circumferential directions; a lock member that is provided between the cap and the casing to restrict rotation of the cap in the circumferential direction on the casing; an elastic member that urges the cap in its axial direction to engage the locking member and the cap; at least one sphere is loosely fitted and supported in a portion of the casing that is covered by the cap; The sphere engages with a ring groove formed in the spindle, and a recess is provided at a predetermined position on the inner surface of the cap so that the sphere can be moved radially outward, and the cap is rotated in the circumferential direction to move the inner surface of the cap. When the concave part of the spindle and the sphere are aligned, the spindle can be attached to and removed from the casing, and when the cap is rotated and the sphere is pressed, the sphere and the concave part of the cap are aligned with the concave groove of the spindle. 1 of the cap in the position
1. A finger chuck attaching/detaching mechanism for a bar feeder, characterized in that the cap is locked by engaging a locking member.
