PROBLEM TO BE SOLVED: To reduce power loss of a compressor and improve lubricity of the compressor with simple structure. SOLUTION: The compressor comprises: an oil conducting passage 40 formed in a rotational shaft 14 along an axial direction of the rotational shaft and communicating with the rotational shaft at the other end 14b of the rotational shaft; a rotor 42 installed near one end 14a of the rotational shaft and rotated integrally with the rotational shaft; and an oil supply passage 42b formed to the rotor, orthogonal to the axial direction of the rotational shaft, and communicating with the oil conducting passage. The lubricating oil in the oil storage chamber is supplied, by rotation of the rotor, to bearings 20, 26, 34 and the compressor unit 10 through the oil conducting passage and the oil supply passage.
