Abstract
A bearing cap () is attached to a bulkhead () of a cylinder block () made of a light metal through a pair of bolts (). The bearing cap () has a frame () made of an iron-based metal and a cast light-alloy part (). The frame () has a pair of pillar parts () through which the bolts () extend and a circular-arc-shaped arch section (). At high temperatures, the span of the pair of the bolts () increases due to thermal expansion of the light-alloy material, and the pair of the pillar parts () expand. This causes the middle part of the arch section () to shift upward, thereby suppressing an increase in bearing clearance.
