To provide a circuit breaker in which, when a fixed side electrode and a movable side electrode transfer from a cut-off state (open) to a turning-on state (close), even if the movable side electrode hits (contacts) the fixed side electrode to cause an impact, repulsive stress is not applied on the movable side electrode, so that the movable side electrode is not temporarily disconnected from the fixed side electrode.SOLUTION: A circuit breaker of the present invention includes a fixed side electrode, a movable side electrode which is disposed to face the fixed side electrode and electrically contacts with the fixed side electrode, and a drive part for driving the movable side electrode. The circuit breaker includes repulsive force mitigation means for mitigating a repulsive force applied on the movable side electrode due to an impact caused when the movable side electrode contacts with the fixed side electrode.SELECTED DRAWING: Figure 3 【課題】固定側電極と可動側電極が遮断状態（開）から投入状態（閉）に移行する時、可動側電極が固定側電極にぶつかる（接触する）衝撃が発生したとしても、可動側電極に反発応力が加わることがなく、一時的に可動側電極が固定側電極との接続状態が外れることがないこと。【解決手段】本発明の遮断器は、上記課題を解決するために、固定側電極と、該固定側電極と対向配置され電気的に接触する可動側電極と、該可動側電極を駆動する駆動部とを備えた遮断器であって、前記遮断器は、前記固定側電極に前記可動側電極が接触する際に生じる衝撃による前記可動側電極に加わる反発力を緩和する反発力緩和手段を備えていることを特徴とする。【選択図】図３
