Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a sliding member excellent in wear resistance, heat resistance, seizure resistance and property to be machined by composing one sliding member of a refined aluminum alloy and composing the other of a sintered aluminum alloy contg. a specified amt. of aluminum nitride among a pair of the sliding members sliding each or the. SOLUTION: Among a pair of sliding members sliding each other, one sliding member (such as a valve case) is composed of a refined aluminum alloy and the other sliding member (such as a valve spool) is composed of a sintered aluminum alloy contg., by weight, 0.5 to 6% aluminum nitride. This sintered aluminum alloy preferably contains 0.1 to 2 wt.% nitrogen and contains >=0.05 wt.% magnesium. Moreover, the aluminum nitride preferably grows fibrously in one direction and the porosity of the sintered aluminum alloy is preferably regulated to
