Abstract
An object of the present invention is to simplify portions of an oil supply passage which portions are formed at a cylinder block. An oil supply device according to the present invention includes a cylinder block, an oil pan, an oil pump, and an oil filter. Wall portions of the oil pan are coupled to wall portions of the cylinder block. An oil filter is attached to the oil pan. An upstream oil supply passage through which the oil filtrated by the oil filter flows is formed at the oil pan. A downstream oil supply passage including a main gallery extending in a cylinder column direction is formed at the cylinder block. A first communication passage through which the main gallery and the upstream oil supply passage communicate with each other is formed at the wall portion of the cylinder block and the wall portion of the oil pan.
