A power transfer apparatus of a clutchless compressor is provided to improve response property and accuracy of the fracture of a limiter by moving the limiter to the shaft direction and blocking power. A power transfer apparatus of a clutchless compressor comprises a pulley(10) having a rotor part(11) rotatably mounted at a front housing(41) and a combining groove(12) formed on the outer peripheral surface to be combined with a belt; a limiter(20) having a limiter hub(21) screw-combined with the end of a driving shaft(42), an outer hub(22) fixed at the pulley, and a breaking part(23) formed at the area of connecting the limiter and outer hubs; and a support ring(30) broken by predetermined pressure. The limiter hub is moved to the screw combined direction to cut the breaking part and block the power transfer by breaking the supporting ring. A notch is circumferentially formed at the breaking part on the driving shaft.
