A disk brake including friction pads disposed opposite to a brake disk, a bracket provided with support portions for movably supporting the friction pads so as to permit sliding along the axial direction of the brake disk, and retainers each interposed between the friction pad and the support portions, to restrain at least movements of the retainers relative to the support portions of the bracket. Of a pad holding force with which the retainer holds the friction pad, and a retainer supporting force for supporting the retainer on the support portion, at least the retainer supporting force is set to be not less than a received force exerted on the friction pad due to vibration. The resulting configuration prevents generation of rattling sounds due to the vibration.
