Abstract

PURPOSE:To form an oil hole without damaging strength of a connecting rod itself by burying infiltrated metal bar at position corresponding to the oil hole position, compacting to compress powder and next, sintering at the time of compacting to compress the powder raw material to the connecting rod shape. CONSTITUTION:The metal powder for raw material is charged in a die to compact the powder compressed green compact 6 having the connecting rood shape. Then, after burying the infiltrated metal bar 5 of copper, etc., having almost the same diameter as the oil hole 4 arranged through from the large end part 1 to the small diameter part 2 of the connecting rod, the powder compressed green compact 6 is compacted. This green compact is sintered or after sintering this, further it is heated and forged. At the time of sintering, the infiltrated metal bar 5 is melted and this part is made to the hole and the oil hole is formed. Together with this, the melting metal is impregnated to the neighborhood thereof and the density of the base material at the position is raised, and fatigue strength near the oil hole 4 is improved.
