An electric brake apparatus includes an electric motor including a plurality of driving circuits, an electric mechanism configured to press a braking member against a braking target member based on driving of the electric motor, and a control device configured to control the driving of the electric motor. The control device detects contact between the braking member and the braking target member based on a change in a current of the electric motor when power is supplied to a part of the driving circuits among the plurality of driving circuits. More specifically, the change amount of the current between before and after the braking member and the braking target member contact each other is larger when power is supplied to a part of the driving circuit than when power is supplied to all of the plurality of driving circuits.

The at least one body includes a connection portion, an extension, and an engagement portion. The at least one rotatory arm includes a pulling segment, a coupling orifice, and a receiving orifice. The at least one brake lever includes a fixing segment connected with at least one electromagnetic clutch which includes a bolt attracted electromagnetically by the at least one electromagnetic clutch after conducting a power, and a defining orifice is defined adjacent to the at least one electromagnetic clutch. The at least one angle signal sensor is configured to sense and send a rotating angle of the rotatable column. The at least one power failure sensor has a movable sensing head.

Provided is an electric parking brake device which enables a service brake that generates a brake force in accordance with an operation input of a vehicle user and a parking brake that generates a brake force with the function of an electric actuator having operation controlled by a control unit to be obtained. The control unit (C) starts to count in response to an end of detection of the service brake by service brake detection means (66) and stops operation of the control unit (C) after an elapse of a first predetermined time from the start of the count. With this configuration, the load on a battery can be reduced by preventing the control unit from being kept activated for a period of time that is longer than necessary.
