ンアツセンブリ。[Claims for Utility Model Registration] A piston body having a cylindrical shape with a bottom, an adjusting nut provided inside the piston body, and a preloaded state inserted between the adjusting nut and the piston body on the outer peripheral side of the adjusting nut. A piston assembly for a disc brake with a parking brake mechanism, comprising a compression coil spring that urges the adjustment nut toward the bottom side of the piston body and presses it against the piston body, the piston assembly being parallel to the axis of the compression coil spring. A spring seat is integrally formed on the inner circumferential surface of the piston body, and the outer diameter of a portion other than the one end of the compression coil spring is set to be smaller than the inner diameter of the spring seat. Piston assembly for disc brake with parking brake mechanism.
