Disk brake for vehicle

Abstract

Disclosed is a disk brake for a vehicle having a power transmission device that presses a friction pad against a disk by using a worm gear. The disk brake includes a movable friction pad that makes contact with one lateral side of a disk rotating together with a vehicle wheel, thereby generating braking force, a wedge member, which is provided at one side thereof with the movable friction pad and moves toward the disk by means of a driving motor generating a driving force, a guide member for guiding the wedge member such that the wedge member moves back and force relative to the disk; and a power transmission device installed between the driving motor and the guide member so as to convert the driving force of the driving motor into a linear movement in a direction perpendicular to a rotating shaft of the driving motor.
