Abstract
A two-cycle engine includes a crank case, a crank shaft carried by the crank case, intake reed valves attached to the crank case, a plurality of balance weights rotating in association with the crank shaft and a plurality of balance rotating shafts bearing the balance weights. In arrangement, the balance weights and the balance rotating shafts are arranged outside the outermost intake reed valves in the axial direction of the crank shaft. In view of the axial direction of the crank shaft, the rotating axes of the balance weights and the center portions of the intake reed valves are arranged on opposing parting planes of the crank case. Thus, it is possible to miniaturize the size of the engine in view of the axial direction. Further, the balance weights can be carried by the balance rotating shafts without being lengthened.
