取りはずすだけで容易に作業か行なえる。The movable closing resistance contact (3) is driven by simply opening and closing a resistance current, which is small compared to a short circuit current for a closing resistance device, so the mass of the contact (3) is small.
It is not necessary to have a large amount of operating force. Therefore,
The rod aυ can be used as a force transmitting element with a twist suitable for transmitting large loads. By rotating the rod aυ in this way and arranging it as shown in Figure 5 (cL), the shafts 03 and I are almost parallel, and the holes in the bearings are also parallel, so the respective bearings can be integrated. Since the hole machining of the bearing can also be performed from the same direction, the integrated bearing member (L7) can be manufactured at low cost without the hassle of setting it at a different machining angle. Also, rod Ql
