An actuator may include: a first gear configured to rotate by a motor; a second gear operably connected to the first gear and configured to convert a rotary movement of the first gear into a linear movement; and a footer configured to move linearly together with the second gear to move a back plate of a brake pad. A stopper protrusion may be provided at one end portion of the first gear, the footer may have a stopper groove having a shape of a substantially circular arc or a partial circle such that the stopper protrusion rotating together with the first gear can be inserted in the stopper groove, and as the footer becomes closer to the one end portion of the first gear, the stopper protrusion may be inserted into the stopper groove to prevent the first gear from rotating.
