Abstract
An internal combustion engine 1 in which the compression ratio can be varied by moving a cylinder block and a crankcase along the axial direction of the cylinder is mounted on a vehicle body member 29 by at least two portions including a first mount portion 32 provided on a transmission apparatus to and a second mount portion 31 provided on the internal combustion engine 1, wherein said second mount portion 31 is provided on the crankcase 4. The first mount portion 32 and the second mount portion 31 are arranged in such a way that the direction of a rotation moment TD about the output shaft RC1 of the transmission apparatus acting on the internal combustion engine 1 upon combustion becomes opposite to the direction of a rotation moment M1 about the output shaft RC1 generated by a force acting on a cylinder block 3 upon changing the compression ratio.
