Beschreibung
Zusammenfassung:	Provided is an electric parking brake device in which a parking lever is driven by an electric actuator. The electric actuator includes: an electric motor which can be rotationally driven in a normal/reverse direction and of which an operation is controlled by a motor control unit in accordance with rotational loads; a converting mechanism which can convert a rotational movement into a linear movement and which can move the parking lever from a returning position to an operating position in accordance with normal rotation of the electric motor and which can move the parking lever from the operating position to the returning position in accordance with reverse rotation of the electric motor; and a load applying mechanism (a stopper, a friction material) which drives components of the converting mechanism and which applies predetermined rotational loads to the electric motor, in a state where the parking lever is moved from the operating position to the returning position in accordance with reverse rotation of the electric motor.
