A structure for a spring chamber is formed by connecting a chamber case and a return spring housing case and includes a piston member and a push rod. The piston member has a spring receiving section which holds a power spring inside the chamber case and a cylinder body section which is interlocked with the spring receiving section. A diaphragm is arranged inside a return spring housing case chamber in the return spring housing case, defines a pressure medium chamber, and is deformed by an advancing and retracting operation of the cylinder body section. The push rod member advance and retract with an operation of the diaphragm, and performs braking or releasing of a brake.
