  "textContent": "It is desired to reduce the power consumption of an electric brake device, while reducing fluctuations in braking force within a permissible range. The brake device includes a control device (3) which performs feedback control using a braking force of a linear motion mechanism (2) as a controlled variable. The control device (3) includes a computing unit (4) for computing an operating quantity (voltage applied to an electric motor (1)) for canceling out fluctuations in braking force, and a frequency detector (5) for detecting the frequency of the operating quantity. The control device (3) further includes an operating quantity limiting unit (6) which limits the operating quantity according to a predetermined parameter when the detected frequency is higher than a predetermined frequency threshold, i.e. when the detected frequency is in a high-frequency range in which the permissible value of the braking force fluctuations is high, whereby it is possible to reduce the output of the electric motor (1) within a range in which the braking force fluctuations does not exceed the permissible value, thereby reducing the power consumption.",
