Disclosed is an electric disc brake. According to an aspect of the present invention, The electric disc brake includes: a carrier in which a pair of pad plates individually pressing both sides of a disc rotating with a wheel are installed to come in or out; a caliper housing installed in the carrier to be able to slide and having a cylinder in which a piston can come in or out by a brake oil pressure; an adjuster arranged inside the piston; a push rod installed in the cylinder and screwed with the adjuster; a lamp unit penetrating the rear part of the cylinder and pressing the push rod toward the piston by receiving a rotation force from an actuator generating a parking brake force and converting the rotation force to a linear motion; an elastic member installed in a spring case formed between the inner circumference of the cylinder and the push rod and providing an elastic force for the push rod; and a connector transferring the rotation force to a rotation lamp plate by being connected to a last output gear among gears, wherein one end is connected to the rotation lamp plate of the lamp unit to be rotated with the rotation lamp plate, and the other end decreases the rotation force from the actuator. At least one long hole is formed in the connector in an arc shape at fixed intervals from the center in the radial direction. A protrusion is formed in the last output gear to rotate along the long hole by passing through the long hole. |
