。 In a lathe chuck having a plurality of chuck pawls that are opened and closed by a chuck pawl drive mechanism on the front part of the chuck body, a chuck pawl mounting base that is opened and closed by the drive mechanism has a chuck that is slidable in and out directions. In addition to providing a connecting block, a recess into which the connecting block is removably fitted is provided on the rear surface of the chuck pawl, and a plurality of engaging protrusions are provided on both front sides of the connecting block and on both rear sides of the recess of the chuck pawl. , and a spring is attached to the chuck pawl mounting base to push the connecting block outward so that the engaging protrusion of the block engages with the engaging protrusion of the chuck pawl. When the outer end of the connecting block is moved inward by pushing the outer end of the chuck pawl mounting base, the engaging protrusion of the connecting block engages with the engaging protrusion of the chuck pawl. A chuck pawl for automatic replacement of a chuck for a lathe, characterized in that it is positioned so that it can be removed from the chuck.
