Abstract
Disclosed is an electromechanical brake including a piston provided to advance and retreat to press a brake pad, a power conversion unit including a spindle provided to rotate by receiving a driving force from an actuator, a nut connected to the spindle to advance or retreat inside the piston depending on rotation directions of the spindle to advance or retreat the piston, and a return means provided to forcibly retreat the piston when the nut retreats, wherein the return means includes a locking protrusion provided to protrude in a radial direction from an outer surface of the nut, and a groove portion provided on an inner surface of the piston to allow the locking protrusion to be inserted.
