PROBLEM TO BE SOLVED: To provide a brake force holding device of a vehicle which can suppress the lowering of brake forces imparted to wheels by suppressing the occurrence of such an event that a claw member is semi-engaged with a displacement member, and an electric brake device of a vehicle.SOLUTION: First lock processing for making a motor 23 generate torque which displaces a ratchet gear 31 to a release direction, or for stopping the drive of the motor 23 in a situation that a claw member 32 is pressed against the ratchet gear 31, second lock processing for setting a rotation angle of the ratchet gear 31 at an agent which is different from a semi-engagement rotation angle by driving the motor 23, and third lock processing for rotating the ratchet gear 31 to the release direction by reversely driving the motor 23 are performed in order in an electric brake device of a vehicle.SELECTED DRAWING: Figure 1
【課題】変位部材に爪部材が半係合される事象の発生を抑制することで、車輪に付与する制動力の低下を抑制することができる車両の制動力保持装置及び車両の電動制動装置を提供する。【解決手段】車両の電動制動装置では、爪部材32をラチェット歯車31に押し付けている状況下で、ラチェット歯車31を解除方向に変位させるためのトルクをモータ23に発生させる、又は、モータ23の駆動を停止させる第1のロック処理と、モータ23を駆動させることでラチェット歯車31の回転角度を半係合回転角度とは異なる角度とする第2のロック処理と、モータ23を逆駆動させることでラチェット歯車31を解除方向に回転させる第3のロック処理とが順番に実施される。【選択図】図1
