軸受構造。[Claims for Utility Model Registration] A reinforcing member is fixed to the cylinder block body,
A bearing cap that cooperates with the cylinder block body to constitute a crankshaft bearing is interposed between the reinforcing member and the cylinder block body, and the bearing cap has a pair of fastening member mounting portions that are connected between the two. The bearing cap is formed so as to be recessed toward the crankshaft side from the central portion of the bearing cap, and the pair of fastening member mounting portions of the bearing cap and the cylinder block body are fixed by the fastening member, and the bearing cap and the reinforcing member are fixed by the fastening member. In the cylinder block bearing structure of an engine to be fixed, a recess is formed in the center of the bearing cap with its opening side facing the reinforcing member, and an inner surface of the recess has a recess extending from the reinforcing member side to the cylinder block main body side. An inclined surface is formed that gradually moves away from the fastening member mounting portion of the bearing cap toward the bearing cap, and the reinforcing member is provided with a pressing portion that presses the inclined surface. The cylinder block bearing structure of the engine.
