- the first and second hinge wings 21 and 22 are formed in a plurality of radially along the circumferential direction with respect to the axis of rotation 21 and 22, so that the first and second wing-side protrusions 45a and 45b are formed in the end. is rotated to the 'folded position' or 'unfolded position' along the semi-circular grooves 21a and 22a and the semi-circular projections 31a and 31b of the rotation support configuration.
- the free stop function is performed by the tension mechanism 50 when the rotational positions of the first and second main bodies 11 and 12 are between the 'unfolded position' and the 'folded position'. do.
- the tension mechanism 50 has the tension guide projections 58b of the first and second tension blades 55 and 56 as shown in FIGS. 9 and 10 through the tension guide holes of the first and second hinge blades 21 and 22. Since it is guided by (58a), when the first and second hinge blades 21 and 22 are rotated, the first and second tension blades 55 and 56 work together to rotate together.
- the tension movable members 53 and 54 by the rotation of the first and second tension wings 55 and 56 ) of the inclined projections (53a, 53b, 54a, 54a) of the first and second tension blades (55, 56) while the inclined projections (55a, 56a, 55b, 56b) are separated from the tension movable members (53, 54) It is moved by pressing in the direction of the hinge axis (see Fig. 12b).
