It may be provided on the body 4 or the attracting tool 5). That is, for example, the first projecting portion 2d and the second projecting portion 2e may be formed so as to be cut out from the base body 3 and the holding body 4, and the thread of the bolt 5a (male screw) in the attracting tool 5 may be formed. The first protrusion 2d and the second protrusion 2e may be used.

  In addition, the female screw may not be formed from the nut 5 b, but the female screw may be directly formed on the inner peripheral surface of the holes 4 b and 3 b of the holding body 4 or the base 3.

  Moreover, the attracting tool 5 may consist of a rivet, even if it does not consist of a male screw and a female screw.

  Even if the connector main body 2a does not include the base body 3 and the holding body 4, which are separate bodies, the base portion corresponding to the base body 3 and the holding portion corresponding to the holding body 4 are connected at one end side.
