ABSTRACT OF THE DISCLOSURE A compression ratio-changing device for an internal combustion engine, includes an oil passageway formed through a connecting rod of the engine and connected to a hydraulic oil source. A combustion chamber volume-changing device is provided in the piston and operable by means of hydraulic pressure supplied from the hydraulic oil source through the oil passageway for changing the volume of the combustion chamber and hence changing the compression ratio of the engine. A hydraulic pressure control valve is arranged in the connecting rod for controlling the supply of the hydraulic pressure to the combustion chamber volume-changing device. A driving device is provided at a cylinder block of the engine for driving the hydraulic pressure control valve to cause the combustion chamber volume-changing device to change the volume of the combustion chamber.
