とができる従って機器の小型化が図れる。As described above, also in this embodiment,
As in the first embodiment, the torsion coil spring 10 can be prevented from floating by the guide plate 61, so that the shape of the torsion coil spring 10 can be simplified. Further, since the guide plate 61 is formed integrally with the mounting plate 60 of the torsion coil spring 10 by pressing or the like, the cost can be reduced. In addition, guide plate 61
By providing the taper T on the base plate, the protruding height of the guide plate 61 can be reduced, so that it is possible to cope with a thin mechanism, and the size of the device can be reduced.

る。As described above, according to the present invention, the dimensional relationship between the coil portion of the torsion coil spring and the guide shaft is reviewed and the shape of the guide shaft is changed, whereby the torsion coil spring can be easily mounted. When a torsional stress is applied, the torsion coil spring does not float. Therefore, the shape of the torsion coil spring can be simplified, and the cost can be reduced. Further, by forming the positioning guide portion of the torsion coil spring into a plate shape and forming the positioning guide portion integrally with the mounting plate of the torsion coil spring by bending, the number of processing steps can be reduced.
