Abstract
In a variable stroke engine comprising a plurality of links () connecting a piston () with a crankshaft (), a control member () disposed on an engine main body so as to be moveable in two directions over a prescribed range relative to the engine main body, a control link () connecting one of the plurality of links with the control member and an actuator (AC) for displacing the control member, the actuator comprises a ratchet mechanism that utilizes a force transmitted from the piston to the control member as an actuating force for the control member. By providing a spring member (, SP,) that applies a biasing force to the control member, an appropriate actuating force can be applied to the control member in either direction.
