Zusammenfassung:	PURPOSE:To provide a connecting rod made of an aluminum powder alloy preventing fretting wear so as to improve the durability of the connecting rod. CONSTITUTION:A connecting rod 1 made of an aluminum powder alloy is provided with a small end part 3 and a large end part 4 at both ends of a rod part 2. The small end part 3 is provided with a first fitting hole 6 for inserting a piston pin through rotatably, while the large end part 4 is provided with a second fitting hole 7 with a large diameter for inserting a crankshaft through rotatably. The large end part 4 can be divided vertically, and the divided members are integrally connected at lateral protruding parts 8 by bolts 9. Hard Ni-P plated layers 10, 11 of 10mum or more in thickness are formed over the whole inner peripheral surface of the first and second fitting holes 6, 7.
