Separator structure of chain case

A separator structure of a chain case for partitioning the interior of said chain case in an internal combustion engine, wherein said chain case accommodates a chain-sprocket mechanism for rotating a crankshaft and camshafts in an interlocking fashion, and at least one of a tensioner shoe for applying a predetermined tension to a slack side of a chain and a guide shoe for preventing the run-out of said chain on a stretched side thereof, said separator structure comprising:

• an end face of the engine;
• an inner surface of a chain cover joined to said end face of said engine, said chain case being defined by coupling said end face and said inner surface;
• and
• a pair of ribs respectively protruded from said end face of said engine and said inner surface of said chain cover,
• wherein at least one of said tensioner shoe and said guide shoe has a surface to which a distal end edge of said rib is directed, said surface is extended in a direction perpendicular to said crankshaft, and at least one of said ribs confronts an end surface of an oscillating support shaft of said tensioner.
