| description | There is provided a bearing apparatus of a crankshaft for an internal combustion engine. The bearing apparatus includes a crankshaft having a plurality of journal portions and a plurality of crank pin portions; a main bearing supporting the crankshaft; and a bearing housing holding the main bearing. The plurality of journal portions include a first journal portion having a lubricating oil passage and a second journal portion not having the lubricating oil passage. The first and second journal portions and are supported by the first and second main bearings and. The bearing housing includes an Al alloy upper housing and an Fe alloy lower housing. The groove depth of the oil groove of the upper half bearing of the second main bearing is one half or less than the groove depth of the oil groove of the upper half bearing of the first main bearing. |
