An electric brake actuator including a retracting torque applying mechanism that applies a retracting torque to a rotational shaft and including: a torsion spring; a stator including a first retaining portion retaining one end portion of the torsion spring; a rotor including a second retaining portion retaining the other end portion of the torsion spring and configured to be rotated relative to the stator so as to twist the torsion spring; and a clutch mechanism configured to selectively establish a clutch ON state and a clutch OFF state, wherein a first retaining portion prohibits the one end portion from being displaced in a forward rotational direction and includes a biasing member that biases the one end portion in the forward rotational direction, the first retaining portion being configured to allow the one end portion to be displaced in a reverse rotational direction against a biasing force of the biasing member.
