ABSTRACT:
A drive device includes a variable compression ratio internal combustion engine that moves a cylinder block relative to crankcase in a cylinder axis direction, and a transmission device. A chain case is made up of a crankcase-side chain case fixed to the crankcase, and a cylinder block-side chain case fixed to the cylinder block. An upper portion of the crankcase-side chain case is supported on a vehicle body via a support member. The transmission device is supported on the vehicle body via the support member. A support member coupling portion that fixes the support member of the crankcase-side chain case includes a rib that improves the rigidity of a front wall portion of the crankcase-side chain case.
