An integrated electric brake apparatus according to the present embodiments comprises: a motor in which a first hollow portion in which a motor shaft is accommodated is formed; a housing to which the motor is coupled, and in which a second hollow portion communicating with the first hollow portion is formed; a piston coupled to the motor shaft and reciprocating between the first hollow portion and the second hollow portion by rotation of the motor shaft; and a cover member which includes an insertion portion provided in the second hollow portion and inserted into the piston, and a coupling portion formed with a larger diameter than the diameter of the insertion portion and supported by the housing, and has an accommodation space formed therein to collect oil leaked between the piston and the insertion portion. In order to prevent the leaked oil from penetrating the motor and causing a breakdown in the motor, a double sealing member is provided. The accommodation space for collecting the oil leaked from the primarily provided sealing member is provided so that the application of hydraulic pressure to the secondarily provided sealing member is deferred until the accommodation space is full, thereby ensuring safety.

    본 실시예들에 의한 일체형 전동식 브레이크 장치는, 모터축이 수용되는 제 1 중공부가 형성되는 모터, 모터가 결합되고, 제 1 중공부와 연통되는 제 2 중공부가 형성되는 하우징, 모터축에 결합되어 모터축의 회전에 의해 제 1 중공부와 제 2 중공부 사이에서 왕복운동하는 피스톤, 제 2 중공부에 구비되되 피스톤에 삽입되는 삽입부와 삽입부보다 큰 직경으로 형성되어 하우징에 지지되는 결합부를 포함하며, 피스톤과 삽입부의 사이로 누유되는 오일이 수집되는 수용공간이 내부에 형성되는 커버부재를 포함하여, 누유된 오일이 모터에 침투되어 모터에 고장이 발생하는 것을 방지하기 위해 실링부재를 이중으로 구비하되 일차적으로 구비된 실링부재에서 누유된 오일이 수집되는 수용공간을 구비함으로써 수용공간이 가득 차기 전까지 이차적으로 구비된 실링부재에 액압이 가해지는 것을 유예하여 안전성을 확보할 수 있다.
