Abstract
The present disclosure relates to a drag reducing structure. The drag reducing structure according to an embodiment of the present disclosure includes: a piston configured to press or release a friction pad pressing at least one side of a disk; a spindle unit configured to move in frontward and backward directions in the piston to press or release the piston; and at least one stopper formed at one side of the piston to come into contact with one side of the spindle unit and move the piston in a backward direction when the spindle unit moves in the backward direction to move the piston when a braking force is released and reduce the drag phenomenon which occurs due to a restoration defect of the piston.
