To provide an electric brake device which can appropriately perform holding of a brake force by locking a brake force holding mechanism according to a situation.SOLUTION: A parking mechanism 23 holds a brake force in such a manner that a rotary shaft 22B1 of an electric motor 22B as a part of a brake mechanism 22 is locked by a ratchet gear 23B and a lever member 23C. An ECU 24 for rear electric brake constitutes a control device for controlling operations of the electric motor 22B and the parking mechanism 23 together with a main ECU 10. The main ECU 10 holds a brake force by the electric motor 22B when a parking brake switch 15 is operated in the state that a vehicle is stopped when the system is operated, and holds the braking force by the parking mechanism 23 when the vehicle transfers to a parking state from a stopped state.SELECTED DRAWING: Figure 2 【課題】制動力保持機構の係止による制動力の保持を状況に応じて適切に行うことができる電動ブレーキ装置を提供する。【解決手段】パーキング機構２３は、ブレーキ機構２２の一部となる電動モータ２２Ｂの回転軸２２Ｂ１をラチェットギヤ２３Ｂとレバー部材２３Ｃとで係止することで、制動力を保持する。リア電動ブレーキ用ＥＣＵ２４は、メインＥＣＵ１０と共に、電動モータ２２Ｂおよびパーキング機構２３の作動を制御する制御装置を構成している。メインＥＣＵ１０は、システムが稼働しているときに、車両が停車状態でパーキングブレーキスイッチ１５が操作された場合、電動モータ２２Ｂで制動力を保持し、停車状態から駐車状態へ移行したときに、パーキング機構２３により制動力を保持する。【選択図】図２
