装置。[Scope of Claim for Utility Model Registration] By providing an exhaust opening/closing valve that can open the exhaust port of the combustion chamber whose stroke phase is near the top dead center of the compression stroke, and blowing out compressed air from the compression stroke from the exhaust port. By absorbing the compression work in the combustion chamber and introducing a part of the ejected air into the combustion chamber through the exhaust valve of the combustion chamber located near the bottom dead center of the intake stroke. An engine braking device that generates braking force by increasing the intake air filling amount and increasing the compression work of the same chamber, comprising: an operating section having a hydraulic system that opens and closes the exhaust opening/closing valve; It can be set in a position in which the hydraulic input system that supplies pressure oil to the system communicates with each other, and in a position in which the hydraulic system and a pressure oil recovery system that recovers pressure oil from this hydraulic system communicate with each other. , a control section that is set in a position where the hydraulic system and the hydraulic input system communicate with each other when the engine brake is activated; and a control section that is arranged in an oil passage that communicates the hydraulic input system of the control section with the pressure oil recovery system. At the same time, an oil chamber having an oil passage between the pressure oil recovery member and the pressure oil recovery member communicating with each of the above systems is formed, and the flow direction of the pressure oil in this oil chamber is controlled so that the pressure oil flows from the pressure oil recovery system to the pressure oil recovery section. and a direction switching control unit capable of switching the pressure oil from the hydraulic input system to the pressure oil recovery system when the engine brake operation is stopped. An engine brake device characterized in that the flow direction of the pressure oil in the direction switching control section is set in the direction in which the pressure oil flows toward the pressure oil recovery system.
