To provide an electric parking brake device which can reduce the power consumption of an electric motor in a case where a parking brake instruction is performed.SOLUTION: An electric parking brake device comprises: a linear motion member which is driven by an electric motor, applies a parking brake by being moved in the forward direction and releases the parking brake by being moved in the retreat direction being the reverse direction to the forward direction; and a controller which controls the electric motor. The controller stops the electric conduction to the electric motor at a time point at which the first prescribed time elapses from a time point at which the electric conduction amount to the electric motor becomes constant when releasing the parking brake.SELECTED DRAWING: Figure 4

    【課題】 駐車ブレーキ指示が行われた場合において、電気モータの電力消費が低減され得る電動駐車ブレーキ装置を提供する。【解決手段】 電動駐車ブレーキ装置は、「電気モータによって駆動され、前進方向に移動されることで駐車ブレーキを効かせ、前記前進方向とは逆方向である後退方向に移動されることで前記駐車ブレーキを解除する直動部材」と、「前記電気モータを制御するコントローラ」と、を備える。そして、前記コントローラは、前記駐車ブレーキを解除する際に、前記電気モータへの通電量が一定になった時点から第1所定時間を経過した時点で前記電気モータへの通電を停止する。【選択図】 図4
