PROBLEM TO BE SOLVED: To reduce the number of parts by eliminating the need for a special sealing measure in a disk brake for a vehicle, comprising an electric motor having a motor shaft provided with an armature, and attached to a caliper body so as to exert power to press a friction pad against a disk rotor side, and a Hall IC for detecting a rotation angle of the electric motor. SOLUTION: The Hall IC 122 disposed in the electric motor to be positioned laterally outward of a pulsar installed in a motor shaft is retained by a motor case 56 of the electric motor and a synthetic resin-made sensor cover 127 detachably attached to the motor case 56.
