装置。 A cylinder chamber has an inlet port connected to the hydraulic oil supply device and an outlet port connected to the brake actuating device, and the cylinder chamber is slidably fitted into the cylinder chamber under the biasing force of a return spring. In a safety device for a brake device, the piston is provided with a small hole opened in the piston so as to communicate between an inlet port side chamber and an outlet port side chamber. A safety device for a brake device, characterized in that it is interposed to allow flow to a port side chamber, but to prevent flow in the opposite direction.
