| Zusammenfassung: | PURPOSE:To provide an operation device having loads at both ends of an operation process like an earthing switch, which is compact and has high practicality, in which difference in operation performance produced is eliminated and smooth operation at reduced operation speed is ensured. CONSTITUTION:An operation device has an input lever 2 and an output lever 10. A crank lever 5 is arranged between the levers 2 and 10. Links 9, 10 connect the lever 2 with the lever 5 and the lever 10 with the lever 5, and the crank lever 5 rotates about 180 deg. and is set so that a lower dead point does not locate at both ends in an operation process. |
