Abstract
A bearing cap () fastened to a bulkhead () of a cylinder block () by bolts to support a crankshaft. A pair of protruding parts () that enlarge a joint surface () between the bearing cap () and the bulkhead () in a transverse direction of the crankshaft are formed respectively in a pair of side surfaces (). A pair of reinforcing parts () are positioned between a top surface () and the pair of protruding parts (), protrude from the pair of side surfaces () in the transverse direction of the crankshaft, and have a protrusion length that is smaller than that of the pair of protruding parts (). The stress on the joint portion between the bearing cap () and the bulkhead () generated by the crankshaft during operation of the internal combustion engine is thereby reduced.
