Abstract
PURPOSE: To control engine noise effectively, by putting elastic members in the rational direction between a crankshaft and a gear above the crankshaft for transmitting the turning moment.
CONSTITUTION: A hermetic space 60 accomodates rubbery elastic member 64, 66 between a projection 52B of inner unit 52 and a projection 20A of smaller gear 20. Provided that the crankshaft 16 is turned in the X direction, the space between the front side of the projection 52B and the projection 20A accomodates the larger elastic member 64, while the space between the rear side and the projection 20A accomodates the smaller one 66. The elastic member is of an arched shape with a nearly square cross section, which is similar to the shape of space 60, and has a stepped portion 64A on both ends each to form a flank. This construction can effectively reduce engine noise caused by fluctuation of revolution.
