In an 8-cylinder internal combustion engine, there is a slave cylinder that is combined with the exhaust valve of each cylinder to drive and open the exhaust valve, a master cylinder that is connected to the slave cylinder through a hydraulic passage, and a brake. During operation, the drive mechanism drives the master cylinder, operates the slave cylinder, and opens the exhaust valve of each cylinder near the top dead center of the compression stroke. It is composed of a mechanism that works in conjunction with either an intake side valve opening mechanism that opens the intake valve in a predetermined cylinder selected from other cylinders, and an exhaust side valve opening mechanism that opens the exhaust valve during the exhaust stroke. An engine braking device for an internal combustion engine characterized by:
