The present invention relates to a drum brake. The drum brake of the present invention comprises: a bolt screw which rotates in conjunction with driving of a first motor; a nut piston which is screwed around the bolt screw and moves in the direction to press a shoe in conjunction with rotation of the bolt screw; and a press nut which is screwed around the nut piston, moves in the axial direction in conjunction with driving of a second motor, contacts the bolt screw, and restrains the nut piston from being pushed out by a reaction force of the shoe. An objective of the present invention is to provide the drum brake, which can be implemented with a simple structure, and an electric parking braking apparatus.

    본 발명은 드럼 브레이크에 관한 것으로, 제1모터의 구동에 연동하여 회전되는 볼트스크류와, 볼트스크류의 둘레에 나사결합되고, 볼트스크류의 회전에 연동하여 슈를 가압하는 방향으로 이동되는 너트피스톤과, 너트피스톤의 둘레에 나사결합되고, 제2모터의 구동에 연동하여 축방향으로 이동되어 볼트스크류와 접하면서 너트피스톤이 슈의 반력에 의해 밀려나는 것을 구속하는 프레스너트를 포함하는 것을 특징으로 한다.
