PURPOSE: A seal assembly of a crank shaft for a vehicle compressor is provided to prevent a leakage of oil or a refrigerant in a compressor and prevent loss of a pressure by removing slip of a seal assembly. CONSTITUTION: A piston is connected with a crank shaft installed under a cylinder block by a connecting rod. A seal assembly(40) is inserted into the crank shaft to prevent a leakage of oil or a refrigerant, and to prevent loss of a pressure. The seal assembly is formed by interposing a compression spring(43), a guide ring(44), an O-ring(45), and a ring-slip(46) between a step part of the crank shaft and a shaft seal cover(42). A slip preventing element is formed at the compression spring, the guide ring, and the ring-slip to prevent slip of the compression spring, the guide ring, and the ring-slip. The slip preventing element is formed of an inner bent part(50) and a receiving groove for receiving the inner bent part.
