PROBLEM TO BE SOLVED: To provide a variable compression ratio internal combustion engine whose compression ratio is changed with a change in the capacity of a combustion chamber, offering technology for developing more stable output. SOLUTION: A crank shaft 8 connected to a piston via a link member is provided separately from an output shaft 9. The rotation of the crank shaft 8 is transmitted to the output shaft via rotation transmitting means 11, 12. When the compression ratio of the internal combustion engine is changed, the crank shaft 8 is moved on a circular arc as a moving passage around the output shaft 9 so that the positions of the top dead center and the bottom dead center of the piston in a cylinder are moved.
