1. An electric parking brake, comprising:
a pair of pressing portions provided in a caliper housing to convert rotational motion into linear motion to press a brake pad;
an actuator configured to transmit power to the pair of pressing portions; and
a load control portion provided rotatably between the pair of pressing portions and the actuator, the load control portion applying a uniform load to the pair of pressing portions by pressing any one of the pair of pressing portions that generates a less load during braking operation,
wherein the caliper housing comprises a pair of coupling parts protruding from the rear of the caliper housing, and
the load control portion is provided between the pair of coupling parts rotatably based on a pin coupled to a center of the load control portion, and opposite ends of the load control portion is provided to face the pair of pressing portions based on the center of the load control portion.
