Abstract
In a link type variable stroke engine in which: a crankshaft and a rotary shaft having an eccentric shaft are each rotatably supported on a case main body formed integrally with a cylinder block and opened at one side to form a part of a crankcase, and a support plate fastened to an opened end of the case main body at a plurality of positions; and a piston, the crankshaft and the eccentric shaft are linked by a linking mechanism, in a projection view on a plane orthogonal to axes of the crankshaft and the rotary shaft, two of the plurality of fastening positions at which the support plate is fastened to the opened end of the case main body are disposed on a straight line passing the axes of the rotary shaft and the crankshaft. This configuration can increase the rigidity between the crankshaft and the rotary shaft enough to prevent change of the distance between the crankshaft and the rotary shaft.
