As a result, the adjustment rotor 79 c can be rotated relative to the outer case 77. Next, when the adjusting rotor 79c is rotated by a minus driver, and the locking projection 79g faces the desired locked hole 77g among the three locked holes 77g, the pushing force of the adjusting rotor 79c by the minus driver is increased. When released, the grooved shaft portion 79f is inserted into the through hole 77e of the one disc 77c of the outer case 77, and the locking projection 79f is inserted into the desired locked hole 77g. As a result, it is possible to adjust the elastic force that widens the gap between the pair of columnar bodies 73c and 73c at both ends of the separation portion 73a of the connection main body 73, that is, the pair of arm portions 73b and 73b. The load of a predetermined value or more in the direction in which the tassels 42 are pulled away from the tuft 11 in a state of loosely fitting to the 11 horizontal portions 11c can be adjusted within a range of 2 to 6 kg, for example.
