A piston is pushed out towards a rotor by an electric actuator. The electric actuator has a speed reduction machine, a ball type speed reduction machine, and a feed-screw device. A preload is imparted to balls which make up the ball type speed reduction machine by a compression spring to impart a resistance against the functioning of the ball type speed reduction machine, whereby the ball type speed reduction machine does not function immediately after braking is started.
