体軸を設けて構成したものである。FIG. 4 shows a conventional structure, in which three jaws 52 are provided on the chuck body 51 in a radial manner and can be slid in an inclined manner for expansion and contraction. The nut 53 is rotatably provided, and a shape retaining ring M for retaining the shape of the rotary nut 53 is attached to the rotary nut 53 by a screw 55.
Fix the male screw of the rotating nut 53 with the jaw 52.
is screwed into the male screw 57 on the outer periphery of the chuck body 51.
Screw the female thread (end) of the tightening nut 59 onto the male thread of the
The retaining ring 61 of the tightening nut 59 is screwed onto the chuck body 51, and a bearing body shaft is provided between the shape retaining ring and the tightening nut 59.
