ーキ装置。[Scope of Claim for Utility Model Registration] (1) An exhaust on-off valve is provided in the exhaust passage of an internal combustion engine, and an intake on-off valve is provided in the intake passage, and both the exhaust on-off valve and the intake on-off valve are closed by operating an exhaust brake switch. The exhaust brake device includes an operation control means for controlling opening and closing operations of the exhaust on-off valve and the intake on-off valve, and an operation state detection means for detecting an engine brake operation state of the engine, and the operation control means includes: An exhaust brake device characterized in that when the engine brake operating state is detected by the operating state detection means, the intake on-off valve is closed while the exhaust on-off valve is kept open. (2) The operation control means further includes a rotation speed sensor that detects the engine rotation speed, and the operation control means detects the engine braking operation state using the second operation state detection means, and detects the engine rotation speed using the rotation speed sensor. The exhaust brake according to claim 1, wherein the exhaust brake is configured to close the intake opening/closing valve while keeping the exhaust opening/closing valve open when it is detected that the number of revolutions is equal to or higher than a predetermined number of revolutions. Device.
