とを特徴とする制動間隙調整装置。 A cylinder chamber, a piston that fits into the cylinder chamber and partitions it into an input chamber and an output chamber, a spring that biases the piston toward the output chamber, a spring provided in the cylinder chamber so as to communicate with the input chamber, and a brake. An inlet passage connected to the control valve, an outlet passage opened in the cylinder chamber so as to communicate with the output chamber and connected to the brake actuation device, a pilot circuit communicating the input chamber and the outlet chamber, and a pilot circuit. In the braking gap adjustment device, the pilot circuit is provided in the piston, and the poppet valve device is connected to the piston, and the poppet valve device is interposed in the circuit and is opened by pressure on the input chamber side. The poppet valve device is incorporated in the circuit, and furthermore, this poppet valve device includes a valve seat formed in the middle of the pilot circuit, a poppet valve arranged to sit on and off from this valve seat, and a poppet valve that seats the poppet valve. The poppet valve includes a spring that biases the poppet valve in the direction, a valve stem protruding from an end of the poppet valve on the output chamber side, and a stopper that abuts the valve stem when the piston moves excessively, thereby disengaging the poppet valve from its seat. A brake clearance adjustment device characterized by:
