ABSTRACT:
A vehicle including a vehicle frame and a power unit suspended from the vehicle frame in a manner to reduce the amplitude of vibration generated by the power unit and also the vibration transmitted to the vehicle frame. The power unit comprises a case, an engine integrally coupled to the case, a drive wheel rotatably supported on the case, and a transmission mechanism disposed in the case for transmitted power from the engine to the drive wheel. The power unit is supported on the vehicle frame by a linkage mechanism and a cushioning unit, the engine having a center where vibratory forces are produced and an associated direction in which primary vibratory forces are produced. The linkage mechanism includes a link extending in a direction substantially normal to the engine-associated direction. The power unit is constructed such that a first straight line extending horizontally and transversely of the vehicle frame through the center of gravity of the power unit and a second straight line extending through the engine's center in the engine-associated direction substantially intersect each other.
