Summary: | PROBLEM TO BE SOLVED: To provide a sliding member for an internal combustion engine, superior in baking resistance, abrasion resistance, and coefficient of friction to an iron sintered material, while keeping an adequate sliding state which has not been realized in sliding between aluminum materials. SOLUTION: This valve timing control device 100 comprises a rotation transmission member consisting of an interior rotor 20 fixed to the top of a cam shaft 10, and an external rotor 30 fitted outward to both the cam shaft and the interior rotor so as to relatively rotate in a predetermined range; and a vane 70 integrated or attached on the interior rotor. The external rotor consists of an aluminum alloy material to which at least one element is added out of 0.05-0.20 wt.% Sb, 0.001-0.01 wt.% Na, 0.001-0.05 wt.% Sr, and 0.0005-0.01 wt.% Ca. The interior rotor or the vane consists of the material which is obtained by means of rapidly cooling and solidifying the aluminum alloy material including at least elements of Si and Fe to form powder, and compacting the powder. |
