Abstract
A two-cycle engine has a balancer shaft driven by a crankshaft of the engine through gears, and a gear cover forming a balancer gear chamber for the gears. The balancer gear chamber is communicated with the atmosphere through a breather passage formed in an upper portion thereof. A labyrinth passage is formed in the balancer gear chamber for breathing air, so as to separate oil from discharging air.
