A link component () with an oil hole (E) is attached to a crankshaft () of an internal combustion engine (E), and the oil hole (E) allows communication from an outside to the crankshaft () side. The oil hole (E) has an inclined surface (F) along an opening rim on the crankshaft () side. A surface other than the oil hole (E) has a carbon concentration of 0.5 wt % or more. The inclined surface (F) has a carbon concentration within a range of 0.7 wt % or more and 0.9 wt % or less. Production cost is suppressed, and at the same time, damage is prevented by increasing resistance of the oil-hole part on which stress is liable to concentrate.
