PURPOSE: A structure for supplying oil for a compressor is provided to restrain frictional contact between a rotary shaft and upper and lower bearings by smoothly supplying oil to a space between a thrust bearing surface of the rotary shaft and bearing surfaces of the upper and lower bearings, thereby minimizing abrasion and friction loss of the rotary shaft and the upper and lower bearings. CONSTITUTION: An axial direction oil through hole(24) is formed at a rotary shaft(20) by passing through the rotary shaft in an axial direction to mount an oil feeder(26) inside. An incline direction oil through hole(27) is inclined in the axial direction to pass through a random position of an inner wall of the axial direction oil through hole and one side thrust bearing surface(T) of a bearing axial part(22). An oil communicating hole(28) is formed to make a hole of the incline direction oil through hole communicate with the other side thrust bearing surface of the bearing axial part.
