ABSTRACT:
In an engine having a propeller mounted on one end of a crankshaft, the vibrations on an end portion of the crankshaft opposite to the propeller are effectively suppressed with a pair of vibration pendulum type weights arranged outside the crankcase whereby it is possible to easily perform a change of the vibration suppression structure in conformity with the property of the propeller.
