The rubber dampered bearing body includes a rubber damper portion and a rubber cylindrical portion formed integrally with the rubber damper portion and extending toward the cylindrical portion. The rubber cylindrical portion and the cylindrical portion are directly connected. The rubber dampered bearing body supports the rear end of a cover for a coupler for connecting an output shaft of the engine and the drive shaft.
