  • an outer edge portion 15 a of the base portion 15 and an outer edge portion 17 a of the circumference connection portion 17 are formed in such a way so as to form a concave shape between the adjacent bar structural members 2 and 2 .
  • the narrow side face portion Hc of the pull member H is formed in such a way so as to form a convex shape matching the concave shape of the outer edge portions 15 a and 17 a .
  • the narrow side face portion Hc can be housed with an excellent appearance between the bar structural member 2 functioning as the exit bar 2 b positioned on one side sandwiching the center axis y, and the bar structural member 2 functioning as the exit bar 2 b positioned on the other side sandwiching the center axis y ( FIG. 22 ).
  • the pull member H can be attached to the string W between the adjacent bar structural members 2 and 2 up and down on a right side sandwiching the center axis y in FIG. 22 as well, or attached to the string W between the adjacent bar structural members 2 and 2 up and down on a left side sandwiching the center axis y in FIG. 22 as well.
  • the narrow side face portion Hc can be housed between the bar structural member 2 functioning as the entrance bar 2 a and the bar structural member 2 functioning as the exit bar 2 b.
  • the present invention is not limited to the embodiment explained hereinabove, and includes all embodiments which can obtain the object of the present invention.
