するブレーキ作動装置。 In a brake actuation device for advancing and retracting a push rod connected to a lining pad of a disc brake via a transmission mechanism, a brake actuation mechanism is provided at the tip of the push rod via a connection mechanism, and the brake actuation mechanism comprises:
A hollow cylindrical piston and a push rod body slidably fitted into the hollow cylindrical piston are housed inside the center of the hollow cylindrical cylinder, and a pressure chamber is provided in which hydraulic pressure is supplied and discharged through the piston and the push rod body. and an operating chamber in which a spring is interposed, and the spring is interposed between the end flange of the push rod body and the side wall of the cylinder so as to constantly bias the push rod body in the direction of contraction. What is claimed is: 1. A brake actuating device, characterized in that the pressure chamber is connected to a hydraulic circuit that connects to a hydraulic pressure supply source.
