PURPOSE:To improve resistance to wear, by a method wherein a compressor is formed by a whiskersreinforced metal compounded by impregnating and coagulating a molten aluminum group metal in an assembly preform of Si whiskers under pressurization. CONSTITUTION:A rotor 4 is engaged with the surroundings of a cam part 3 of a cam shaft 2, and the lower end of a partition vane 6, resiliently held on a rotor 4 through the force of a spring 5, is brought into contact with the rotor 4. A compressor member, e.g. a vane 6, a rotor 4, is formed by a whiskers- reinforced metal. The whiskers-reinforced metal is compounded by impregnating and coagulating a molten an aluminum group alloy in an assembly preform of Si whiskers under pressurization and has a whiskers volume content of 25-40%.
