タ。 A non-circular cylinder formed in a carrier body, and a membrane-like elastic bag inserted into the cylinder along its inner wall and clamped and held in the inner part of the cylinder around the entire circumference of the open end wall. , and a cup-shaped retainer that is inserted over the bag so that the peripheral wall meets the inner wall of the cylinder, and the bottom wall connected to the peripheral wall is interposed between the back plate of the friction material, and the bag is introduced into the cylinder. In a disc brake actuator configured to receive fluid pressure on its inner surface and press the friction material through a retainer to move forward and come into sliding contact with the disc rotor, there is a partition between the inner wall of the cylinder, the retainer, and the elastic bag. An actuator for a disc brake, characterized in that a back-up ring is provided in a gap in which one end side along the peripheral wall edge of the retainer has at least the same thickness as the peripheral wall of the retainer, and the inner corner edge is removed at the other end side. .
