PROBLEM TO BE SOLVED: To provide a scroll compressor improving lubricity of a bearing by reducing gas refrigerant generated from lubricating oil of which pressure decrease at the bearing. SOLUTION: This compressor is provided with a fixed scroll and a rocking scroll provided in a hermetic vessel and mutually meshing to form a compression chamber between plate shape scroll teeth thereof, a frame supporting a main shaft driving the rocking scroll in a radial direction, a main bearing and an auxiliary main bearing provided in the frame and supporting the main shaft in the radial direction, and a space provided in an axial direction of the main bearing and the auxiliary main bearing, and an oil supply groove communicating to the space at an upper end thereof and provided to have a lower end thereof stop in a middle of the auxiliary main bearing and twisted in a reverse rotation direction of the main shaft toward the lower end side from the upper end on an outer circumference surface of the main shaft. Lubricating oil is pumped to the auxiliary main bearing by feeding lubricating oil to the space through an oil feeding hole provided on the main shaft in the axial direction.
