Abstract
Abstract An autobicycle wherein the cooling effect is improved without particularly increasing the wind introducing area of the autobicycle. The autobicycle comprises a partition wall located between a rear portion of an engine carried on a body frame and a body side cover for partitioning the inside of the body side cover to define front and rear sectional chambers. The body side cover continuously covers a range at least from a side portion of the engine to a location below a seat supported above the body frame and has one or more air admitting holes perforated therein. Air admitted into the inside of the body side cover thus cools the engine and some other components of the autobicycle in the front chamber and independently cools different components in the rear chamber.
