Engine starting apparatus

An engine starting apparatus comprising:

• a case attachable to an engine, the case defining an inner space for accommodating a starter;
• a motor mounting seat formed in the case for mounting thereon a starter motor of a self-starter mechanism;
• a plurality of first louvers formed around a portion of the periphery of an inner wall of the case proximate the motor mounting seat and extending from the inner wall of the case toward the engine;
• and a plurality of second louvers formed on an outer wall of the case and extending from the case toward the engine, the second louvers being formed around a portion of the periphery of the outer wall of the case at portions of the periphery of the case at which the first louvers are not formed;
• wherein external air is taken in by the first and second louvers around the entire periphery of the case during operation of the engine.

An engine starting apparatus for starting an engine, comprising:

• a case comprised of an outer case and a case cover defining an interior space, the outer case having at least first, second and third bolt apertures for attaching the case to an engine;
• a motor mounting seat provided in an inner wall of the outer case for mounting thereon a starter motor for starting the engine;
• a recoil starter mechanism disposed in the interior space of the case for starting the engine, the recoil starter mechanism having a starting rope pulling port disposed adjacent to the first bolt aperture, the starter motor being selectively disposed either between the first bolt aperture and the third bolt aperture when the starting rope pulling port is positioned between the first bolt aperture and the second bolt aperture, or between the first bolt aperture and the second bolt aperture when the starting rope pulling port is positioned between the first bolt aperture and the third bolt aperture;
• a plurality of first louvers extending from an outer surface of the case cover;
• and a plurality of second louvers formed on a wall of the outer case;
• wherein external air is taken in by the first and second louvers around the entire periphery of the case during operation of the engine.
