Abstract:
A vibration reduction device ( 5 ) including: a counterweight ( 6 ) provided to a crankshaft ( 14 ) of a Stirling engine ( 1 ); and an electric balancer ( 7 ) being attached to a crankcase ( 15 ) and including a balance weight ( 73 ) rotated by an electric motor ( 74 ). An inertial force of the counterweight ( 6 ) is set to approximately a half of a combined inertial force of pistons ( 12, 13 ). Inertial force of balance weight×L2=½×combined inertial force of pistons×L1 is satisfied when a mass of the balance weight is set, where L1 denotes a distance between a vibration reduction target position and a rotation center (O 1 ) of the crankshaft ( 14 ), and L2 denotes a distance between the vibration reduction target position and a rotation center (O 2 ) of the balance weight ( 73 ).

Claim (Index 5):
The vibration reduction device according to  claim 1 , wherein\n a rotational power source of the balance shaft and the balance weight in the balancer is an electric motor, the crankshaft is connected to an electricity generator configured to generate electricity by making use of rotation of the crankshaft, and part of the electricity generated by the electricity generator is supplied to the electric motor.
