キゾーストブレーキのバキユームシリンダ構造。 The cylinder body is divided into a variable pressure chamber and a constant pressure chamber via a diaphragm, and the diaphragm is urged by a return spring and linked to a valve in the exhaust pipe, so that the variable pressure chamber is communicatively connected to the vacuum pump and the air cleaner. In an exhaust brake vacuum cylinder structure in which a constant pressure chamber is opened to the atmosphere through a communication hole in the cylinder body, an opening/closing valve is provided on the lowest surface of the diaphragm to communicate the variable pressure chamber and the constant pressure chamber when the exhaust brake is not in operation. The vacuum cylinder structure of the exhaust brake is characterized by
