  As shown in FIGS. 2 and 3, the second core support portion 2 is provided on a base 24 that can be positioned with a screw 26 with respect to the shaft 3 in a state where the core support member 23 is rotatable. A stopper 24a for the core support member 23 is formed at one end of the base 24, and a screw portion 24b for attaching a nut 25 is formed at the other end. The movement of the core support member 23 in the axial direction is restricted by the stopper 24 a and the nut 25.

  The core support member 23 is provided with a flat portion 20 on a part of a cylindrical peripheral surface, and an elastic deformation body 22 is fixed to the flat portion 20 by a fixing member 21. This elastic deformable body 22 is made of an elastic body that has high durability against repeated deformation and is difficult to break, and is a string-shaped body having a circular cross section with a hardness of about Hs80 to Hs95. It is suitable from the point of hardness at the time.

  In FIG. 3, the fixing member 21 is arranged on the upper left side and the lower right side so as to form an arc that reaches the arcuate vertex of the elastic deformation body 22 near the end of the flat portion 20. Of course, an embodiment in which the elastic deformable body 22 is only one of the upper left side and the lower right side can be employed.
