Abstract
A motor-driven disk brake has a first brake pad and a second brake pad disposed at opposite sides of a disk rotor, a piston disposed so as to face the first brake pad, a claw portion extending over the disk rotor and facing the second brake pad, and an electric motor disposed in the vicinity of the piston. A ball ramp mechanism for converting rotation of the electric motor to a linear motion is disposed between the first brake pad and the electric motor. When the motor is operated, the piston is reciprocally moved by the ball ramp mechanism, to thereby enable application and removal of a braking force relative to the disk rotor by the brake pads.
