ABSTRACT:
A bearing beam structure of an automotive internal combustion engine having a cylinder block formed with bearing sections, consists of a plurality of main bearing cap sections each of which associates with each cylinder block bearing section to rotatably support the journal of a crankshaft. First and second side wall sections are provided to be respectively connected with the opposite side portions of each bearing cap section to securely connect the bearing cap sections with each other. Additionally, the first and second side wall sections are respectively formed with first and second transmission installation sections to which a transmission housing is rigidly connected, thereby greatly improving the rigidity of the cylinder block entire while improving the connection-rigidity between the cylinder block and a transmission.
