Connecting rod and method of producing the same

摘要

A connecting rod (1) includes a rod main body (10), a small end (20) located at one end of the rod main body (10) and a big end (30) located at another end of the rod main body (10), the big end (30) including a curved section (30R) which is curved so as to become narrower toward the rod main body (10). The big end (30) is formed of a metal material whose composition is different from that of the rod main body (10), and is bonded to the rod main body (10). A joint (W) between the big end (30) and the rod main body (10) is located closer to the small end (20) than is an end (RE) of the curved section (30R) facing the rod main body (10).
