The invention relates to an electric brake device. An electric brake device (10) generates a braking force on a wheel (13) by applying a pressing force by a piston (19) by means of a linear motion of the piston (19) in accordance with the transmission of rotational torque from an electric motor (15) to a linear motion conversion mechanism (16) in the positive direction. The electric brake device (10) is provided with a one-way clutch (42) that cuts off the transmission of rotational torque between the electric motor (15) and the linear motion conversion mechanism (16) when a rotational torque having a magnitude equal to or greater than a predetermined value is applied to the electric brake device (10) in a direction opposite to the forward direction. 本发明涉及电动制动装置。电动制动装置(10)通过活塞(19)利用与从电动机(15)向直线运动转换机构(16)的正方向的旋转转矩的传递对应的该活塞(19)的直线运动来施加推压，从而使车轮(13)产生制动力。在这样的电动制动装置(10)设置有单向离合器(42)，在施加了既定值以上的大小的与正方向相反方向的旋转转矩时，该单向离合器(42)切断电动机(15)与直线运动转换机构(16)之间的旋转转矩的传递。
