A switchgear includes a stationary contact, a movable contact able to be shifted between a closed position and an opened position, an electromagnetic actuator able to generate power for shifting the movable contact, the electromagnetic actuator including a stator and a movable element, and a power transmission unit able to shift the movable contact, and to press the movable contact against the stationary contact. The power transmission unit includes a drive unit-side spring bearing portion able to be shifted together with the movable element, a contact-side spring bearing portion to be opposed to the drive unit-side spring bearing portion, and able to be shifted together with the movable contact, and a spring member provided between the drive unit-side spring bearing portion and the contact-side spring bearing portion. |
