ABSTRACT:
To reduce the size and weight and the number of parts required for a chain cover apparatus for an engine, the chain cover for covering a chain for transmitting a rotational force of a crankshaft to at least one camshaft mounted on a cylinder head comprises a chain cover formed with a cylindrical hollow projection portion extending frontward and having a hole through which the crankshaft is passed, and an oil pump accommodated within the cylindrical hollow projection portion and driven by the crankshaft. Further, the chain cover is formed with a semicircular flange portion formed at a lower wall of the cylindrical hollow projection portion so as to be joined with an oil pump, and with two flat flanges formed on both sides of the cylindrical hollow projection portion so as to be joined between the oil pan and the engine block.
