A scroll compressor is provided. That is, in a shaft penetration scroll compressor in which an eccentric portion of the rotational shaft is overlapped with an orbiting wrap of the orbiting scroll in a radial direction, an oil hole that supplies oil inhaled through an oil passage of the rotational shaft to a thrust bearing surface of the orbiting scroll may be formed at the fixed scroll, and thus, the orbiting scroll may be supported by pressure of oil supplied to the thrust bearing surface through the oil hole to prevent tilting of the orbiting scroll due to eccentricity of a gas force, thereby enhancing reliability and performance of the compressor.
