1. An electro-mechanical brake comprising a pair of brake pads disposed on both sides of a disc, comprising:
a motor that provides a rotational driving force;
a pair of rotating screws that respectively rotates about a pair of second rotating shafts parallel to a first rotating shaft of the motor, and is arranged in parallel to each other in a direction perpendicular to an extending direction of the second rotating shafts;
a power transmission unit that transmits the rotational driving force of the motor to the pair of rotating screws;
a pair of pistons that is respectively coupled to the pair of rotating screws to be able to move forward and backward to press the disc with the brake pads and is disposed symmetrically with centers of the brake pads therebetween; and
a load adjuster that is rotatably installed between the pair of rotating screws and the power transmission unit and applies a uniform load to the pair of rotating screws by pressing the pair of rotating screws toward the disc,
wherein the power transmission unit includes a first gear coupled to the first rotating shaft of the motor, second gears coupled to the second rotating shafts of the rotating screws, and a third gear engaging with the first gear and the second gear and rotating about a third rotating shaft.
