- the other member, for example, the lid is fixed to the non-circular portion 1f of the portion 1c so as not to rotate. Then, when the lid is opened and closed with respect to the main body, the movable shaft 1 rotates with respect to the case 5, and the spring washer 12, the holding washer 4 and the nut 7 also rotate. At this time, the fixed plate 3 does not rotate.
- the spring washer 2 and the fixed plate 3 are pressed by the nut 7 via the presser disc 4 and are in contact with each other.
- the pulling washer 2 rotates in contact with the fixed plate 3. Therefore, at the rotational position where the projection 2 of the spring washer 2 overlaps with the projection 3c of the fixed plate, the spring washer 2 is compressed and the urging force of contact with the projection 3c of the fixed plate becomes strong.

- FIG. 8 (a) when the position of the protrusion 3c of the fixed plate 3 is a and the intermediate point between the protrusions 3c and 3c is b, the generated rotational torque is as shown in FIG. Therefore, in order to prevent the lid from falling, for example, a large torque should be applied near the closed position of the lid (the first point a in Fig. 9), and a small torque should be applied near the standing position (point b in Fig. 9).
- a large torque is generated near the 180 ° open position (point a in the back of Fig. 9), and the required torque is generated at each position to prevent the lid from falling and to maintain the lid at an arbitrary angle. It is possible.
- Such a torque characteristic is most suitable for use in a laptop computer.
