Patent
CA 2299087
The interior of a chain case 23 accommodating therein a chain-sprocket mechanism (a sprocket 12 and a silent chain 14) provided for rotating a crankshaft 11 and camshafts 5 in an interlocking fashion and a tensioner shoe 18 for applying a predetermined tension to a slack side of a chain or a guide shoe 19 for preventing the run-out of the chain on a stretched side thereof is partitioned by providing a rib 27, 28 so as to protrude from at least either of an end face of an engine E and an inner surface of a chain cover 22 joined to the end face with distal end edges of the ribs being directed toward sides 18a, 18b of the tensioner shoe or the guide shoe that are perpendicular to the crankshaft. According to this construction, since the rib provided so as to protrude from the cylinder block or the chain cover cooperates with the tensioner shoe or the guide shoe so as to form a separator, an oil passage having a sufficient cross-sectional area can be defined without control from the chain line and necessity of enlargement of the engine.
