Abstract: An electric parking brake device includes: a “linear motion member configured to be driven by an electric motor, moved in a forward direction so as to apply a parking brake and moved in a backward direction opposite to the forward direction so as to release the parking brake”; and a “controller configured to control the electric motor”. When the parking brake is released, the controller stops energization to the electric motor at a time point when a first predetermined time elapses after a time point when an energization amount to the electric motor becomes constant.
