Engine cover device for light vehicles

Abstract

An engine cover device for light vehicles including a cover main body for use in covering a driven wheel and a power unit from the outsides thereof, a first partition wall for separating the driven wheel and the power unit, and a second partition wall for separating a muffler and other associated equipment units for the engine such as an air cleaner, a carburetor and the like. The second partition wall is arranged such that a space for the installation of the muffler is formed at a rear part of an air discharge port of a forced air cooling device for the engine, and the front part of the cover main body is projected outwardly as it is extended from its front end toward its rear part so as to provide for formation of an air communication hole at the side surface of the cover. The engine cover device is useful for protecting the associated equipment units for the engine against mud, water, and dust, and also protecting other peripheral units of the engine from high temperatures generated by the muffler, the engine cover device being suitable for cooling an interior of the cover and in particular for providing an efficient cooling of the muffler. The engine cover device is provided with a resilient member for biasing a split-type cover member constituting a part of the cover main body toward an engaged position with its supporting member and thereby a positive holding of the split-type cover member may be made when it is to be assembled.
