To provide a vehicular brake device which can inhibit increase of motor starting current when a parking brake force is generated.SOLUTION: A vehicular brake device 100 includes: a housing having a through hole; a screw shaft which is guided by an inner peripheral surface of the housing and penetrates through the through hole; an elastic member disposed at a portion where the screw shaft driven by a motor and the housing are butted; and a torque control unit which controls torque of the motor based on a motor current of the motor detected in a process in which the elastic member is compressed.SELECTED DRAWING: Figure 1
【課題】駐車ブレーキ力を発生する際のモータ始動電流の増加を抑制できる車両用ブレーキ装置を提供する。【解決手段】車両用ブレーキ装置100は、貫通孔を有するハウジングと、前記ハウジングの内周面に案内され前記貫通孔を貫通するねじ軸と、モータにより駆動される前記ねじ軸と前記ハウジングとが突き当てられる部分に配置される弾性部材と、前記弾性部材が圧縮される過程で検出される前記モータのモータ電流に基づき、前記モータのトルクを制御するトルク制御部と、を備える。【選択図】図1
