。[Claims for Utility Model Registration] A friction pad disposed opposite to a disc rotor, and a piston having a cylindrical shape with a bottom and fitted into a cylinder portion of a caliper with its opening facing the friction pad. and tip portions of one or more first and second elastic arms whose center portions are fixed to the back surface of the friction pad and which extend from the center portion toward the outer and inner circumferential sides of the disc rotor, respectively. an anti-rattle spring that is brought into contact with the inner circumferential surface of the piston based on its own elastic force and thereby prevents rattling of the friction pad; and a torque plate that supports the friction pad from the inner circumference side. In the disc brake, the center of action of the reaction force of the elastic force acting on the inner circumferential surface of the piston from the tip of the first elastic arm is between the supporting force of the friction pad by the torque plate and the second elastic arm. The first part is located on or near a straight line parallel to the radial direction of the rotor, passing through the center of action of the resultant force of the reaction force of the elastic force acting on the inner circumferential surface of the piston from the tip of the first part. A disc brake characterized in that a contact position of an elastic arm portion to the inner circumferential surface of the piston is determined.
