A1
Abstract:
This bearing metal is for supporting a shaft, such as a piston pin, that is installed in a through hole formed in, for example, a small end portion of a connecting rod such that the connecting rod can pivot about the shaft. The bearing metal comprises a body that is installed on an internal circumferential surface of the through hole and a sliding surface that is formed on an inner circumference of the body and configured to be slidable with respect to the shaft. A flexible support section is formed in at least a portion of the interior of the body, the flexible support section having a lower rigidity than surrounding portions and supporting both end portions of the sliding surface in an elastically deformable manner.
