At least one piece of an adjusting plate (4) having at least one through-hole (41, 42) is provided on the middle of the string. The string is one piece of string consisting of an upper ring (3A) which connects the upper through-holes of the pair of fixed plates with each other, a lower ring (3B) which connects the lower through-holes of the pair of fixed plates with each other, and linear portions on the fixed plates which connect the upper ring and the lower ring.
