Claim 2:
3. A vacuum circuit breaker comprising:
a tubular grounded tank;
an insulating rod disposed within the grounded tank to be movable in an axial direction of the grounded tank;
an operating device provided at one end portion of the grounded tank, the operating device applying a driving force in the axial direction of the grounded tank to one end portion of the insulating rod;
a tubular first bushing connected to a side of the grounded tank;
a tubular second bushing connected to the side of the grounded tank at a greater distance from the one end portion of the grounded tank than the first bushing in the axial direction of the grounded tank;
bushing terminals provided at end portions of the first bushing and the second bushing opposite the grounded tank;
a vacuum valve including a vacuum container, a fixed contact, and a movable contact, the vacuum container being provided within the first bushing, the fixed contact and the movable contact facing each other and being disposed within the vacuum container;
a fixed conductor connecting the fixed contact and the bushing terminal of the first bushing;
a movable conductor electrically connected at one end portion to the movable contact;
a lever rotatably provided within the grounded tank and rotatably coupled at one end portion to the insulating rod;
a link rotatably coupled at one end portion to another end portion of the movable conductor and rotatably coupled at another end portion to another end portion of the lever;
