To prevent interference of a vane with a housing by receiving the maximum load generated on a control shaft between a housing bearing part and a vane shaft, in a variable stroke characteristics engine varying the moving stroke of a piston by driving the control shaft to operate a variable stroke link mechanism with a vane type hydraulic actuator provided on the control shaft connected to the piston and a crankshaft through the variable stroke link mechanism.
In this variable stroke characteristics engine varying the moving stroke of the piston by driving the control shaft to operate the variable stroke link mechanism with the vane type hydraulic actuator AC provided coaxially with the control shaft 65, a clearance C1 between the bearing surface of the housing HU of the actuator AC and the peripheral surface of a vane shaft 66 is formed narrower than a clearance C2 between the inner peripheral surface of a vane hydraulic chamber 86 and the peripheral surface of a vane 87.
