Abstract
In a disk brake for a vehicle, an electric motor is attached to a caliper body so as to exhibit a power for urging a friction pad toward a disk rotor. The electric motor includes a brush holder for holding brushes which contact a commutator at positions at even distances in a circumferential direction of an armature. Internal feed terminals are disposed in the brush holder so as to provide connection between the brushes and feed wires respectively leading to the brushes. A rotational angle detecting sensor is disposed in the brush holder so as to detect a rotational angle of the electric motor. The rotational angle detecting sensor is disposed in the brush holder on a side opposite from the internal feed terminals with respect to the armature. Thus, it is possible to improve assemblability of the rotational angle detecting sensor to the brush holder, and facilitate operation of connecting the feed wires to the brush holder.
