Disclosed is a disk brake. According to an embodiment of the present invention, provided is a disk brake including a carrier having a pair of pad plates installed to be able to move forward and backward; and a caliper housing installed on the carrier to be able to slide and having a cylinder in which a piston is installed to be moved forward and backward by braking hydraulic pressure. The disk brake comprises: an adjuster installed inside the piston to prevent the pad plates from becoming more distant from a disk and maintain a constant gap; a pushrod having a flange part installed in the cylinder to prevent rotation by having a front part screwed to the adjuster and having a rear part formed to expand toward the inner circumference surface of the cylinder; a lamp arranged at the front of the flange part and having a first elastic member integrally included to provide an elastic force to the pushrod; a spring case having an end at one side fixed to the cylinder and forming a predetermined receiving space between the inner circumference surface of the cylinder and the pushrod; and a second elastic member arranged in the receiving space of the spring case to provide an elastic force to the lamp and the pushrod, wherein the first and second elastic members are arranged in series. |
