<p>Disclosed is an electronic disc brake. The electronic disc brake is capable of stably returning a piston after braking and improves a returning effect at the same time. According to an embodiment of the present invention, an electronic disc brake includes: a carrier where a pair of pad plates is installed to be moved forward and backward and a caliper housing installed in the carrier to be slid, including a cylinder where the piston is moved by braking oil pressure; the electronic disc brake including an adjuster installed inside the piston, preventing the pad plates from moving away from a disc, and maintaining the pad plates at constant intervals from the disc; a pushrod installed inside the cylinder and includes the front part coupled with the adjuster by a screw, and the rear part where a flange unit extended to the inner circumference of the cylinder is formed; a lamp unit wherein the rear part of the pushrod is insert-installed inside the cylinder to prevent the rotation of the pushrod, and connected to a parking cable to press the pushrod to the piston; a spring case including one end fixated to the cylinder, and a predetermined reception space between the inner circumference of the cylinder and the pushrod; first and second elastic members formed inside the reception space of the spring case in a row providing an elastic force to the pushrod; and a supporting plate including one end supported by the lamp unit interposed between the first and second elastic members is provided.</p> |
