That is, when the rotating member 4 is in the fully opened state, both ends of the torsion bar 8 in the free state may be simply locked to the fixed end 2 and the male screw member 9. In this case, the urging energy in the opening direction is accumulated in the torsion bar 8 by the rotation of the rotating member 4 in the closing direction. The opening and closing of the rotating member 4 are determined by the torsion direction of the torsion bar 8. Then, the other fixed end 13 is fixed to the fixing member 1 with the screw 16 and the cap 17 is put on to complete the assembly.
