PROBLEM TO BE SOLVED: To provide a highly reliable compressor, without generating fine metallic powder, when fixing an oil feeding pipe to a crankshaft. SOLUTION: The oil feeding pipe 143 is formed of a stainless steel material, and has a conical centrifugal pump part 147 forming a substantially conical shape and having the lower end opening in lubricating oil and an abutting part 142 having the upper end molded in a tapered shape, and is fixed to the crankshaft 125 by fitting a rotor 137 by shrinkage fit in a state of allowing the abutting part 142 to abut on a lower end part 128 of a shaft similarly molded in a tapered shape.
