PROBLEM TO BE SOLVED: To provide an electric parking brake actuator having a simple structure as much as possible, which enables an emergency operation of a parking brake by stored energy in the case that any failure occurs in an electric motor, which has a further compact structure, which avoids a defect related to an inversion operation of the electric motor, and which has a simple structure as much as possible.SOLUTION: An electric parking brake actuator has a transmission mechanism which is accommodated in a housing and can be rotatably driven by an electric motor. An operation rod at the time of a normal operation can be so electrically driven as to be displaced from an unblocking position to a blocking position and vice versa, and is energized in a direction toward the blocking position by a spring element. For an emergency operation, a stop surface can be released by a locking device so that the operation rod is moved to the blocking position without electrically-driven type support as a result of a force of the spring element.SELECTED DRAWING: Figure 16

    【課題】電気モータの障害の場合に蓄積エネルギーによる駐車ブレーキの緊急作動を可能にし、よりコンパクトな構造であり、電気モータの反転動作と関係がある欠点を回避する、可能な限り単純な構造である電気駐車ブレーキアクチュエータを提供する。【解決手段】電気駐車ブレーキアクチュエータは、ハウジング内に収容され、電気モータによって回転可能に駆動可能である伝動機構を有する。通常動作時の作動ロッドは、伝動機構によるアンブロッキング位置からブロッキング位置へおよび逆の電動による変位が可能であり、ブロッキング位置の方向にばね要素によって付勢される。緊急動作のために、停止面は、作動ロッドが、ばね要素の力の結果として、電動式支援なしでブロッキング位置へと移動するように、ロッキングデバイスによって解除可能である。【選択図】図16
