An engine lubrication structure equipped with: a crankcase formed by a pair of half-cases divided at a dividing surface; an cylinder block; and an oil supply path. The oil supply path is equipped with: a first oil passage; a second oil passage; a first bypass hole, one end of which communicates with the first oil passage and the other end of which communicates with a region of the divided surface that is separated from the joining surface between one of the half-cases and the cylinder block; and a second bypass hole, one end of which communicates with the second oil passage and the other end of which communicates with a region of the divided surface that is separated from the joining surface between the other half-case and the cylinder block. The other end of the first bypass hole and the other end of the second bypass hole are connected so as to communicate with each other in the divided surface. |
