Abstract
An oil pump attachment structure is provided for an engine. The oil pump attachment structure includes an oil pump 9 coaxially driven by the crankshaft 2. A pump housing 10 of the pump 9 is disposed between a front cover 7 for covering timing chains 5a, 5b and crank sprockets 3a, 3b while leaving a clearance against the front cover 7. The pump housing 10 is also fastened to a cylinder block 1 so as to straddle the timing chains 5a, 5b, through stays 11a, 11b, 11c by bolts 12. With this arrangement, pulsation produced during the operation of the oil pump 9 is not transmitted to the front cover 7 directly, so that noise radiated from a front face of the front cover 7 can be reduced.
